Content


Typography

Documentation and examples for Bootstrap typography, including global settings, headings, body text, lists, and more.

Headings

All HTML headings, <h1> through <h6>, are available.

H1 heading

H2 heading

H3 heading

H4 heading

H5 heading
H6 heading
<h1>H1 heading</h1>
<h2>H2 heading</h2>
<h3>H3 heading</h3>
<h4>H4 heading</h4>
<h5>H5 heading</h5>
<h6>H6 heading</h6>

.h1 through .h6 classes are also available, for when you want to match the font styling of a heading but cannot use the associated HTML element.

H1 heading

H2 heading

H3 heading

H4 heading

H5 heading
H6 heading
<h1 class="h1">H1 heading</h1>
<h2 class="h2">H2 heading</h2>
<h3 class="h3">H3 heading</h3>
<h4 class="h4">H4 heading</h4>
<h5 class="h5">H5 heading</h5>
<h6 class="h6">H6 heading</h6>

Display headings

Traditional heading elements are designed to work best in the meat of your page content. When you need a heading to stand out, consider using a display heading—a larger, slightly more opinionated heading style. Keep in mind these headings are not responsive by default, but it’s possible to enable responsive font sizes.

Display 1

Display 2

Display 3

Display 4

<h1 class="display-1">Display 1</h1>
<h1 class="display-2">Display 2</h1>
<h1 class="display-3">Display 3</h1>
<h1 class="display-4">Display 4</h1>

Lead

Make a paragraph stand out by adding .lead.

This is a lead paragraph. It stands out from regular paragraphs.

<p class="lead">This is a lead paragraph. It stands out from regular paragraphs.</p>

Inline text elements

Styling for common inline HTML5 elements.

You can use the mark tag to highlight text.

This line of text is meant to be treated as deleted text.

This line of text is meant to be treated as no longer accurate.

This line of text is meant to be treated as an addition to the document.

This line of text will render as underlined

This line of text is meant to be treated as fine print.

This line rendered as bold text.

This line rendered as italicized text.

<p>You can use the mark tag to <mark>highlight</mark> text.</p>
<p><del>This line of text is meant to be treated as deleted text.</del></p>
<p><s>This line of text is meant to be treated as no longer accurate.</s></p>
<p><ins>This line of text is meant to be treated as an addition to the document.</ins></p>
<p><u>This line of text will render as underlined</u></p>
<p><small>This line of text is meant to be treated as fine print.</small></p>
<p><strong>This line rendered as bold text.</strong></p>
<p><em>This line rendered as italicized text.</em></p>

.mark and .small classes are also available to apply the same styles as <mark> and <small> while avoiding any unwanted semantic implications that the tags would bring.

While not shown above, feel free to use <b> and <i> in HTML5. <b> is meant to highlight words or phrases without conveying additional importance while <i> is mostly for voice, technical terms, etc.

Text utilities

Change text alignment, transform, style, weight, and color with our text utilities and color utilities.

Abbreviations

Stylized implementation of HTML’s <abbr> element for abbreviations and acronyms to show the expanded version on hover. Abbreviations have a default underline and gain a help cursor to provide additional context on hover and to users of assistive technologies.

Add .initialism to an abbreviation for a slightly smaller font-size.

attr

HTML

<p><abbr title="attribute">attr</abbr></p>
<p><abbr title="HyperText Markup Language" class="initialism">HTML</abbr></p>

Blockquotes

For quoting blocks of content from another source within your document. Wrap <blockquote class="blockquote"> around any HTML as the quote.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.

<blockquote>
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
</blockquote>
Naming a source

Add a <footer class="blockquote-footer"> for identifying the source. Wrap the name of the source work in <cite>.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.

Someone famous in Source Title
<blockquote class="blockquote">
  <p class="mb-0">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
  <footer class="blockquote-footer">Someone famous in <cite title="Source Title">Source Title</cite></footer>
</blockquote>
Alignment

Use text utilities as needed to change the alignment of your blockquote.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.

Someone famous in Source Title
<blockquote class="blockquote text-center">
  <p class="mb-0">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
  <footer class="blockquote-footer">Someone famous in <cite title="Source Title">Source Title</cite></footer>
</blockquote>

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.

Someone famous in Source Title
<blockquote class="blockquote text-right">
  <p class="mb-0">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
  <footer class="blockquote-footer">Someone famous in <cite title="Source Title">Source Title</cite></footer>
</blockquote>

Lists

Display a list of items inside your content, rendered with a number, a bullet, or none.

Unordered list
  • Lorem ipsum
  • Phasellus iaculis
  • Nulla volutpat
<ul>
  <li>Lorem ipsum</li>
  <li>Phasellus iaculis</li>
  <li>Nulla volutpat</li>
</ul>
Ordered list
  1. Lorem ipsum
  2. Phasellus iaculis
  3. Nulla volutpat
<ol>
  <li>Lorem ipsum</li>
  <li>Phasellus iaculis</li>
  <li>Nulla volutpat</li>
</ol>
Unstyled list

Remove the default list-style and left margin on list items (immediate children only). This only applies to immediate children list items, meaning you will need to add the class for any nested lists as well.

  • Lorem ipsum
  • Phasellus iaculis
  • Nulla volutpat
<ul class="list-unstyled">
  <li>Lorem ipsum</li>
  <li>Phasellus iaculis</li>
  <li>Nulla volutpat</li>
</ul>
Inline list

Remove a list’s bullets and apply some light margin with a combination of two classes, .list-inline and .list-inline-item.

  • Lorem ipsum
  • Phasellus iaculis
  • Nulla volutpat
<ul class="list-inline">
  <li class="list-inline-item">Lorem ipsum</li>
  <li class="list-inline-item">Phasellus iaculis</li>
  <li class="list-inline-item">Nulla volutpat</li>
</ul>
Description list alignment

Align terms and descriptions horizontally by using our grid system’s predefined classes (or semantic mixins). For longer terms, you can optionally add a .text-truncate class to truncate the text with an ellipsis.

Description lists
A description list is perfect for defining terms.
Euismod

Vestibulum id ligula porta felis euismod semper eget lacinia odio sem nec elit.

Donec id elit non mi porta gravida at eget metus.

Malesuada porta
Etiam porta sem malesuada magna mollis euismod.
Truncated term is truncated
Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus.
Nesting
Nested definition list
Aenean posuere, tortor sed cursus feugiat, nunc augue blandit nunc.
<dl class="row">
  <dt class="col-sm-3">Description lists</dt>
  <dd class="col-sm-9">A description list is perfect for defining terms.</dd>

  <dt class="col-sm-3">Euismod</dt>

Code

Documentation and examples for displaying inline and multiline blocks of code with Bootstrap..

Inline code

Wrap inline snippets of code with <code>. Be sure to escape HTML angle brackets.

For example, <section> should be wrapped as inline
For example, <code>&lt;section&gt;</code> should be wrapped as inline.

Code blocks

Use <pre>s for multiple lines of code. Once again, be sure to escape any angle brackets in the code for proper rendering. You may optionally add the .pre-scrollable class, which will set a max-height of 340px and provide a y-axis scrollbar.

<p>Sample text here...</p>
<p>And another line of sample text here...</p>
<pre><code>&lt;p&gt;Sample text here...&lt;/p&gt;
&lt;p&gt;And another line of sample text here...&lt;/p&gt;
</code></pre>

Variables

For indicating variables use the <var> tag.

y = mx + b
<var>y</var> = <var>m</var><var>x</var> + <var>b</var>

User input

Use the <kbd> to indicate input that is typically entered via keyboard.

To switch directories, type cd followed by the name of the directory.
To edit settings, press ctrl + ,

<p>To switch directories, type <kbd>cd</kbd> followed by the name of the directory.<br> To edit settings, press <kbd><kbd>ctrl</kbd> + <kbd>,</kbd></kbd></p>

Sample output

For indicating sample output from a program use the <samp> tag.

This text is meant to be treated as sample output from a computer program.
<samp>This text is meant to be treated as sample output from a computer program.</samp>

Icons

More than 1,550 beautifully crafted icons with some helper classes.

FontAwesome

Font Awesome gives you scalable vector icons that can instantly be customized — size, color, drop shadow, and anything that can be done with the power of CSS.

<i class="fa fa-home"></i>
More examples

You can see the list of available icons online.


Images

Documentation and examples for opting images into responsive behavior (so they never become larger than their parent elements) and add lightweight styles to them—all via classes.

Responsive images

Images in Bootstrap are made responsive with .img-fluid. max-width: 100%; and height: auto; are applied to the image so that it scales with the parent element.

Responsive image Responsive image
<img src="..." class="img-fluid" alt="...">

Image thumbnails

In addition to our border-radius utilities, you can use .img-thumbnail to give an image a rounded 1px border appearance.

200x200 200x200
<img src="..." class="img-thumbnail" alt="...">

Aligning images

Align images with the helper float classes or text alignment classes. block-level images can be centered using the .mx-auto margin utility class.

200x200 200x200 200x200 200x200
<img src="..." class="rounded float-left" alt="...">
<img src="..." class="rounded float-right" alt="...">
Placeholder 200x200
<img src="..." class="rounded mx-auto d-block" alt="...">
Placeholder 200x200
<div class="text-center">
  <img src="..." class="rounded" alt="...">
</div>

Picture

If you are using the <picture> element to specify multiple <source> elements for a specific <img>, make sure to add the .img-* classes to the <img> and not to the <picture> tag.

<picture>
  <source srcset="..." type="image/svg+xml">
  <img src="..." class="img-fluid img-thumbnail" alt="...">
</picture>

Object fit image

400x400 400x400
<div class="img object-fit">
  <div class="object-fit-cover">
    <img src="..." alt="Objet fit image">
  </div>
</div>

Tables

Documentation and examples for opt-in styling of tables (given their prevalent use in JavaScript plugins) with Bootstrap.

Examples

Due to the widespread use of tables across third-party widgets like calendars and date pickers, we’ve designed our tables to be opt-in. Just add the base class .table to any <table>, then extend with custom styles or our various included modifier classes.

Using the most basic table markup, here’s how .table-based tables look in Bootstrap. All table styles are inherited in Bootstrap 4, meaning any nested tables will be styled in the same manner as the parent.

# First Last Handle
1 Mark Otto @mdo
2 Jacob Thornton @fat
3 Larry the Bird @twitter
<table class="table">
  <thead>
    <tr>
      <th scope="col">#</th>
      <th scope="col">First</th>
      <th scope="col">Last</th>
      <th scope="col">Handle</th>
    </tr>
  </thead>
  <tbody>
    <tr>

      <th scope="row">3</th>
      <td>Larry</td>
      <td>the Bird</td>
      <td>@twitter</td>
    </tr>
  </tbody>
</table>

You can also invert the colors—with light text on dark backgrounds—with .table-dark.

Create responsive tables by wrapping any .table with .table-responsive{-sm|-md|-lg|-xl}, making the table scroll horizontally at each max-width breakpoint of up to (but not including) 576px, 768px, 992px, and 1120px, respectively.

Captions

A <caption> functions like a heading for a table. It helps users with screen readers to find a table and understand what it’s about and decide if they want to read it.

Responsive tables

Responsive tables allow tables to be scrolled horizontally with ease. Make any table responsive across all viewports by wrapping a .table with .table-responsive. Or, pick a maximum breakpoint with which to have a responsive table up to by using .table-responsive{-sm|-md|-lg|-xl}.

Always responsive

Across every breakpoint, use .table-responsive for horizontally scrolling tables.

# Heading Heading Heading Heading Heading Heading Heading Heading Heading
1 Cell Cell Cell Cell Cell Cell Cell Cell Cell
2 Cell Cell Cell Cell Cell Cell Cell Cell Cell
3 Cell Cell Cell Cell Cell Cell Cell Cell Cell
<div class="table-responsive">
  <table class="table">
    ...
  </table>
</div>
Breakpoint specific

Use .table-responsive{-sm|-md|-lg|-xl} as needed to create responsive tables up to a particular breakpoint. From that breakpoint and up, the table will behave normally and not scroll horizontally.

These tables may appear broken until their responsive styles apply at specific viewport widths.

# Heading Heading Heading Heading Heading Heading Heading Heading

Figures

Documentation and examples for displaying related images and text with the figure component in Bootstrap.

Anytime you need to display a piece of content—like an image with an optional caption, consider using a <figure>.

Use the included .figure , .figure-img and .figure-caption classes to provide some baseline styles for the HTML5 <figure> and <figcaption> elements. Images in figures have no explicit size, so be sure to add the .img-fluid class to your <img> to make it responsive.

400x300 400x300
A caption for the above image.
<figure class="figure">
  <img src="..." class="figure-img img-fluid rounded" alt="...">
  <figcaption class="figure-caption">A caption for the above image.</figcaption>
</figure>

Aligning the figure’s caption is easy with our text utilities.

Components


Alerts

Provide contextual feedback messages for typical user actions with the handful of available and flexible alert messages.

Examples

Alerts are available for any length of text, as well as an optional dismiss button. For proper styling, use one of the eight required contextual classes (e.g., .alert-success).

<div class="alert alert-primary" role="alert">A simple primary alert—check it out!</div>
<div class="alert alert-secondary" role="alert">A simple secondary alert—check it out!</div>
<div class="alert alert-success" role="alert">A simple success alert—check it out!</div>
<div class="alert alert-danger" role="alert">A simple danger alert—check it out!</div>
<div class="alert alert-warning" role="alert">A simple warning alert—check it out!</div>
<div class="alert alert-info" role="alert">A simple info alert—check it out!</div>
<div class="alert alert-light" role="alert">A simple light alert—check it out!</div>
<div class="alert alert-dark" role="alert">A simple dark alert—check it out!</div>

Additional content

Alerts can also contain additional HTML elements like headings, paragraphs and dividers.

<div class="alert alert-success" role="alert">
  <h4 class="alert-heading">Well done!</h4>
  <p>Aww yeah, you successfully read this important alert message. This example text is going to run a bit longer so that you can see how spacing within an alert works with this kind of content.</p>
  <hr>
  <p class="mb-0">Whenever you need to, be sure to use margin utilities to keep things nice and tidy.</p>
</div>

Dismissing

Using the alert JavaScript plugin, it’s possible to dismiss any alert inline.

You can see this in action with a live demo:

<div class="alert alert-warning alert-dismissible fade show" role="alert">
  <strong>Holy guacamole!</strong> You should check in on some of those fields below.
  <button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span></button>
</div>

Badges

Documentation and examples for badges, our small count and labeling component.

Example

Badges scale to match the size of the immediate parent element by using relative font sizing and em units.

Heading New

Heading New

Heading New

Heading New

Heading New
Heading New
<h1>Heading <span class="badge badge-primary">New</span></h1>
<h2>Heading <span class="badge badge-primary">New</span></h2>
<h3>Heading <span class="badge badge-primary">New</span></h3>
<h4>Heading <span class="badge badge-primary">New</span></h4>
<h5>Heading <span class="badge badge-primary">New</span></h5>
<h6>Heading <span class="badge badge-primary">New</span></h6>

Badges can be used as part of links or buttons to provide a counter.

<button type="button" class="btn btn-primary">Notifications <span class="badge badge-light">4</span></button>

Note that depending on how they are used, badges may be confusing for users of screen readers and similar assistive technologies. While the styling of badges provides a visual cue as to their purpose, these users will simply be presented with the content of the badge. Depending on the specific situation, these badges may seem like random additional words or numbers at the end of a sentence, link, or button.

Unless the context is clear (as with the “Notifications” example, where it is understood that the “4” is the number of notifications), consider including additional context with a visually hidden piece of additional text.

<button type="button" class="btn btn-primary">Profile <span class="badge badge-light">9</span><span class="sr-only">unread messages</span></button>

Contextual variations

Add any of the below mentioned modifier classes to change the appearance of a badge.

Primary Secondary Success Danger Warning Info Light Dark
<span class="badge badge-primary">Primary</span>
<span class="badge badge-secondary">Secondary</span>
<span class="badge badge-success">Success</span>
<span class="badge badge-danger">Danger</span>
<span class="badge badge-warning">Warning</span>
<span class="badge badge-info">Info</span>
<span class="badge badge-light">Light</span>
<span class="badge badge-dark">Dark</span>

Pill badges

Use the .badge-pill modifier class to make badges more rounded (with a larger border-radius and additional horizontal padding). Useful if you miss the badges from v3.

Primary Secondary Success Danger Warning Info Light Dark
<span class="badge badge-pill badge-primary">Primary</span>
<span class="badge badge-pill badge-secondary">Secondary</span>
<span class="badge badge-pill badge-success">Success</span>
<span class="badge badge-pill badge-danger">Danger</span>
<span class="badge badge-pill badge-warning">Warning</span>
<span class="badge badge-pill badge-info">Info</span>
<span class="badge badge-pill badge-light">Light</span>
<span class="badge badge-pill badge-dark">Dark</span>

Buttons

Use Bootstrap’s custom button styles for actions in forms, dialogs, and more with support for multiple sizes, states, and more.

Examples

Bootstrap includes several predefined button styles, each serving its own semantic purpose, with a few extras thrown in for more control.

<button type="button" class="btn btn-primary">Primary</button>
<button type="button" class="btn btn-secondary">Secondary</button>
<button type="button" class="btn btn-success">Success</button>
<button type="button" class="btn btn-danger">Danger</button>
<button type="button" class="btn btn-warning">Warning</button>
<button type="button" class="btn btn-info">Info</button>
<button type="button" class="btn btn-light">Light</button>
<button type="button" class="btn btn-dark">Dark</button>

<button type="button" class="btn btn-link">Link</button>

Disable text wrapping

If you don’t want the button text to wrap, you can add the .text-nowrap class to the button. In Sass, you can set $btn-white-space: nowrap to disable text wrapping for each button.

Button tags

The .btn classes are designed to be used with the <button> element. However, you can also use these classes on <a> or <input> elements (though some browsers may apply a slightly different rendering).

When using button classes on <a> elements that are used to trigger in-page functionality (like collapsing content), rather than linking to new pages or sections within the current page, these links should be given a role="button" to appropriately convey their purpose to assistive technologies such as screen readers.

Link
<a class="btn btn-primary" href="#" role="button">Link</a>
<button class="btn btn-primary" type="submit">Button</button>
<input class="btn btn-primary" type="button" value="Input">
<input class="btn btn-primary" type="submit" value="Submit">
<input class="btn btn-primary" type="reset" value="Reset">

Outline buttons

In need of a button, but not the hefty background colors they bring? Replace the default modifier classes with the .btn-outline-* ones to remove all background images and colors on any button.

<button type="button" class="btn btn-outline-primary">Primary</button>
<button type="button" class="btn btn-outline-secondary">Secondary</button>
<button type="button" class="btn btn-outline-success">Success</button>
<button type="button" class="btn btn-outline-danger">Danger</button>
<button type="button" class="btn btn-outline-warning">Warning</button>
<button type="button" class="btn btn-outline-info">Info</button>
<button type="button" class="btn btn-outline-light">Light</button>
<button type="button" class="btn btn-outline-dark">Dark</button>

Sizes

Fancy larger or smaller buttons? Add .btn-lg or .btn-sm for additional sizes.

<button type="button" class="btn btn-primary btn-sm">Small</button>
<button type="button" class="btn btn-primary">Default</button>
<button type="button" class="btn btn-primary btn-lg">Large</button>

Create block level buttons—those that span the full width of a parent—by adding .btn-block.

<button type="button" class="btn btn-primary btn-block">Block level button</button>

Button active

Buttons will appear pressed (with a darker background, darker border, and inset shadow) when active. There’s no need to add a class to <button>s as they use a pseudo-class. However, you can still force the same active appearance with .active (and include the aria-pressed="true" attribute) should you need to replicate the state programmatically.

<a href="#" class="btn btn-primary active" role="button" aria-pressed="true">Link</a>

Button disabled

Make buttons look inactive by adding the disabled boolean attribute to any <button> element.

<button type="button" class="btn btn-primary" disabled>Button</button>

Disabled buttons using the <a> element behave a bit different:

  • <a>s don’t support the disabled attribute, so you must add the .disabled class to make it visually appear disabled.
  • Some future-friendly styles are included to disable all pointer-events on anchor buttons. In browsers which support that property, you won’t see the disabled cursor at all.
  • Disabled buttons should include the aria-disabled="true" attribute to indicate the state of the element to assistive technologies.
<a href="#" class="btn btn-primary disabled" tabindex="-1" role="button" aria-disabled="true">Link</a>

Button plugin

Do more with buttons. Control button states or create groups of buttons for more components like toolbars.

Toggle states

Add data-toggle="button" to toggle a button’s active state. If you’re pre-toggling a button, you must manually add the .active class and aria-pressed="true" to the <button>.

<button type="button" class="btn btn-primary" data-toggle="button" aria-pressed="false">Single toggle</button>
Checkbox and radio buttons

Bootstrap’s .button styles can be applied to other elements, such as <label>s, to provide checkbox or radio style button toggling. Add data-toggle="buttons" to a .btn-group containing those modified buttons to enable their toggling behavior via JavaScript and add .btn-group-toggle to style the <input>s within your buttons. Note that you can create single input-powered buttons or groups of them.

The checked state for these buttons is only updated via click event on the button. If you use another method to update the input—e.g., with <input type="reset"> or by manually applying the input’s checked property—you’ll need to toggle .active on the <label> manually.

Note that pre-checked buttons require you to manually add the .active class to the input’s <label>.

<div class="btn-group-toggle" data-toggle="buttons">
  <label class="btn btn-primary active">
    <input type="checkbox" checked> Checked
  </label>
</div>
<div class="btn-group btn-group-toggle" data-toggle="buttons">
  <label class="btn btn-primary active">
    <input type="radio" name="options" id="option1" checked> Active
  </label>
  <label class="btn btn-primary">
    <input type="radio" name="options" id="option2"> Radio
  </label>
  <label class="btn btn-primary">
    <input type="radio" name="options" id="option3"> Radio
  </label>
</div>

Button group

Group a series of buttons together on a single line with the button group, and super-power them with JavaScript.

Basic example

Wrap a series of buttons with .btn in .btn-group. Add on optional JavaScript radio and checkbox style behavior with our buttons plugin.

<div class="btn-group" role="group" aria-label="Basic example">
  <button type="button" class="btn btn-primary">Left</button>
  <button type="button" class="btn btn-primary">Middle</button>
  <button type="button" class="btn btn-primary">Right</button>
</div>

Button toolbar

Combine sets of button groups into button toolbars for more complex components. Use utility classes as needed to space out groups, buttons, and more.

<div class="btn-toolbar" role="toolbar" aria-label="Toolbar with button groups">
  <div class="btn-group mr-2" role="group" aria-label="First group">
    <button type="button" class="btn btn-primary">1</button>
    <button type="button" class="btn btn-primary">2</button>
    <button type="button" class="btn btn-primary">3</button>
    <button type="button" class="btn btn-primary">4</button>
  </div>
  <div class="btn-group mr-2" role="group" aria-label="Second group">
    <button type="button" class="btn btn-primary">5</button>
    <button type="button" class="btn btn-primary">6</button>
    <button type="button" class="btn btn-primary">7</button>
  </div>
  <div class="btn-group" role="group" aria-label="Third group">
    <button type="button" class="btn btn-primary">8</button>
  </div>
</div>

Sizing

Instead of applying button sizing classes to every button in a group, just add .btn-group-* to each .btn-group, including each one when nesting multiple groups.



<div class="btn-group btn-group-lg" role="group" aria-label="...">...</div>
<div class="btn-group" role="group" aria-label="...">...</div>
<div class="btn-group btn-group-sm" role="group" aria-label="...">...</div>

Nesting

Place a .btn-group within another .btn-group when you want dropdown menus mixed with a series of buttons.

<div class="btn-group" role="group" aria-label="Button group with nested dropdown">
  <button type="button" class="btn btn-primary">1</button>
  <button type="button" class="btn btn-primary">2</button>
  <div class="btn-group" role="group">
    <button id="btnGroupDrop1" type="button" class="btn btn-primary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Dropdown</button>
    <div class="dropdown-menu" aria-labelledby="btnGroupDrop1">
      <a class="dropdown-item" href="#">Dropdown link</a>
      <a class="dropdown-item" href="#">Dropdown link</a>
    </div>
  </div>
</div>

Vertical variation

Make a set of buttons appear vertically stacked rather than horizontally. Split button dropdowns are not supported here.

<div class="btn-group-vertical">
  ...
</div>

Card

Bootstrap’s cards provide a flexible and extensible content container with multiple variants and options.

About

A card is a flexible and extensible content container. It includes options for headers and footers, a wide variety of content, contextual background colors, and powerful display options. If you’re familiar with Bootstrap 3, cards replace our old panels, wells, and thumbnails. Similar functionality to those components is available as modifier classes for cards.

Example

Cards are built with as little markup and styles as possible, but still manage to deliver a ton of control and customization. Built with flexbox, they offer easy alignment and mix well with other Bootstrap components. They have no margin by default, so use spacing utilities as needed.

Below is an example of a basic card with mixed content and a fixed width. Cards have no fixed width to start, so they’ll naturally fill the full width of its parent element. This is easily customized with our various sizing options.

Image cap Image cap
Card title

Some quick example text to build on the card title and make up the bulk of the card's content.

Go somewhere
<div class="card" style="width: 18rem;">
  <img src="..." class="card-img-top" alt="...">
  <div class="card-body">
    <h5 class="card-title">Card title</h5>
    <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
    <a href="#" class="btn btn-primary">Go somewhere</a>
  </div>
</div>

Content types

Cards support a wide variety of content, including images, text, list groups, links, and more. Below are examples of what’s supported.

Body

The building block of a card is the .card-body. Use it whenever you need a padded section within a card.

This is some text within a card body.
<div class="card">
  <div class="card-body">This is some text within a card body.</div>
</div>
Images

.card-img-top places an image to the top of the card. With .card-text, text can be added to the card. Text within .card-text can also be styled with the standard HTML tags.

Placeholder Image cap

  <div class="card-body">
    <a href="#" class="card-link">Card link</a>
    <a href="#" class="card-link">Another link</a>
  </div>
</div>

Sizing

Cards assume no specific width to start, so they’ll be 100% wide unless otherwise stated. You can change this as needed with custom CSS, grid classes, grid Sass mixins, or utilities.

Using grid markup

Using the grid, wrap cards in columns and rows as needed.

Card images

Cards include a few options for working with images. Choose from appending “image caps” at either end of a card, overlaying images with card content, or simply embedding the image in a card.

Image caps

Similar to headers and footers, cards can include top and bottom “image caps”—images at the top or bottom of a card.

Horizontal

Using a combination of grid and utility classes, cards can be made horizontal in a mobile-friendly and responsive way. In the example below, we remove the grid gutters with .no-gutters and use .col-md-* classes to make the card horizontal at the md breakpoint. Further adjustments may be needed depending on your card content.

Card layout

In addition to styling the content within cards, Bootstrap includes a few options for laying out series of cards. For the time being, these layout options are not yet responsive.

Card groups

Use card groups to render cards as a single, attached element with equal width and height columns. Card groups start off stacked and use display: flex; to become attached with uniform dimensions starting at the sm breakpoint.

Grid cards

Use the Bootstrap grid system and its .row-cols classes to control how many grid columns (wrapped around your cards) you show per row. For example, here’s .row-cols-1 laying out the cards on one column, and .row-cols-md-2 splitting four cards to equal width across multiple rows, from the medium breakpoint up.

Card columns

Cards can be organized into Masonry-like columns with just CSS by wrapping them in .card-columns. Cards are built with CSS column properties instead of flexbox for easier alignment. Cards are ordered from top to bottom and left to right.

Heads up! Your mileage with card columns may vary. To prevent cards breaking across columns, we must set them to display: inline-block as column-break-inside: avoid isn’t a bulletproof solution yet.

Collapse

Toggle the visibility of content across your project with a few classes and our JavaScript plugins.

How it works

The collapse JavaScript plugin is used to show and hide content. Buttons or anchors are used as triggers that are mapped to specific elements you toggle. Collapsing an element will animate the height from its current value to 0. Given how CSS handles animations, you cannot use padding on a .collapse element. Instead, use the class as an independent wrapping element.

Example

Click the buttons below to show and hide another element via class changes:

  • .collapse hides content
  • .collapsing is applied during transitions
  • .collapse.show shows content

Generally, we recommend using a button with the data-target attribute. While not recommended from a semantic point of view, you can also use a link with the href attribute (and a role="button"). In both cases, the data-toggle="collapse" is required.

<a class="btn btn-primary" data-toggle="collapse" href="#collapseExample" role="button" aria-expanded="false" aria-controls="collapseExample">Link with href</a>
<button class="btn btn-primary" type="button" data-toggle="collapse" data-target="#collapseExample" aria-expanded="false" aria-controls="collapseExample">Button with data-target</button>

  </div>
</div>

Multiple targets

A <button> or <a> can show and hide multiple elements by referencing them with a JQuery selector in its href or data-target attribute. Multiple <button> or <a> can show and hide an element if they each reference it with their href or data-target attribute

  </div>

Accordion example

Using the card component, you can extend the default collapse behavior to create an accordion. To properly achieve the accordion style, be sure to use .accordion as a wrapper.

Forms

Examples and usage guidelines for form control styles, layout options, and custom components for creating a wide variety of forms.

Form controls

Textual form controls—like <input>s, <select>s, and <textarea>s—are styled with the .form-control class. Included are styles for general appearance, focus state, sizing, and more.

Be sure to explore our custom forms to further style <select>s.

<form>
  <div class="form-group">
    <label for="exampleFormControlInput1">Email address</label>
    <input type="email" class="form-control" id="exampleFormControlInput1" placeholder="name@example.com">
  </div>
  <div class="form-group">
    <label for="exampleFormControlSelect1">Example select</label>
    <select class="form-control" id="exampleFormControlSelect1">
      <option>1</option>
      <option>2</option>
      <option>3</option>
      <option>4</option>
      <option>5</option>
    </select>
  </div>
  <div class="form-group">
    <label for="exampleFormControlSelect2">Example multiple select</label>
    <select multiple class="form-control" id="exampleFormControlSelect2">
      <option>1</option>
      <option>2</option>
      <option>3</option>
      <option>4</option>
      <option>5</option>
    </select>
  </div>
  <div class="form-group">
    <label for="exampleFormControlTextarea1">Example textarea</label>
    <textarea class="form-control" id="exampleFormControlTextarea1" rows="3"></textarea>
  </div>
</form>

For file inputs, swap the .form-control for .form-control-file.

<form>
  <div class="form-group">
    <label for="exampleFormControlFile1">Example file input</label>
    <input type="file" class="form-control-file" id="exampleFormControlFile1">
  </div>
</form>
Sizing

Set heights using classes like .form-control-lg and .form-control-sm.

<input class="form-control form-control-lg" type="text" placeholder=".form-control-lg">
<input class="form-control" type="text" placeholder="Default input">
<input class="form-control form-control-sm" type="text" placeholder=".form-control-sm">
<select class="form-control form-control-lg">
  <option>Large select</option>
</select>

<select class="form-control">
  <option>Default select</option>
</select>

<select class="form-control form-control-sm">
  <option>Small select</option>
</select>
Readonly

Add the readonly boolean attribute on an input to prevent modification of the input’s value. Read-only inputs appear lighter (just like disabled inputs), but retain the standard cursor.

<input class="form-control" type="text" placeholder="Readonly input here..." readonly>
Readonly plain text

If you want to have <input readonly> elements in your form styled as plain text, use the .form-control-plaintext class to remove the default form field styling and preserve the correct margin and padding.

<form>
  <div class="form-group row">
    <label for="staticEmail" class="col-sm-2 col-form-label">Email</label>
    <div class="col-sm-10">
      <input type="text" readonly class="form-control-plaintext" id="staticEmail" value="email@example.com">
    </div>
  </div>
  <div class="form-group row">
    <label for="inputPassword" class="col-sm-2 col-form-label">Password</label>
    <div class="col-sm-10">
      <input type="password" class="form-control" id="inputPassword">
    </div>
  </div>
</form>
<form class="form-inline">
  <div class="form-group mb-2">
    <label for="staticEmail2" class="sr-only">Email</label>
    <input type="text" readonly class="form-control-plaintext" id="staticEmail2" value="email@example.com">
  </div>
  <div class="form-group mx-sm-3 mb-2">
    <label for="inputPassword2" class="sr-only">Password</label>
    <input type="password" class="form-control" id="inputPassword2" placeholder="Password">
  </div>
  <button type="submit" class="btn btn-primary mb-2">Confirm identity</button>
</form>

Range input

Set horizontally scrollable range inputs using .form-control-range.

<form>
  <div class="form-group">
    <label for="formControlRange">Example Range input</label>
    <input type="range" class="form-control-range" id="formControlRange">
  </div>
</form>

Checkboxes and radios

Default checkboxes and radios are improved upon with the help of .form-check, a single class for both input types that improves the layout and behavior of their HTML elements. Checkboxes are for selecting one or several options in a list, while radios are for selecting one option from many.

Disabled checkboxes and radios are supported. The disabled attribute will apply a lighter color to help indicate the input’s state.

Checkboxes and radio buttons support HTML-based form validation and provide concise, accessible labels. As such, our <input>s and <label>s are sibling elements as opposed to an <input> within a <label>. This is slightly more verbose as you must specify id and for attributes to relate the <input> and <label>.

Default (stacked)

By default, any number of checkboxes and radios that are immediate sibling will be vertically stacked and appropriately spaced with .form-check.

<div class="form-check">
  <input class="form-check-input" type="checkbox" value="" id="defaultCheck1">
  <label class="form-check-label" for="defaultCheck1">Default checkbox</label>
</div>

<div class="form-check">
  <input class="form-check-input" type="checkbox" value="" id="defaultCheck2" disabled>
  <label class="form-check-label" for="defaultCheck2">Disabled checkbox</label>
</div>
<div class="form-check">
  <input class="form-check-input" type="radio" name="exampleRadios" id="exampleRadios1" value="option1" checked>
  <label class="form-check-label" for="exampleRadios1">Default radio</label>
</div>

<div class="form-check">
  <input class="form-check-input" type="radio" name="exampleRadios" id="exampleRadios2" value="option2">
  <label class="form-check-label" for="exampleRadios2">Second default radio</label>
</div>

<div class="form-check">
  <input class="form-check-input" type="radio" name="exampleRadios" id="exampleRadios3" value="option3" disabled>
  <label class="form-check-label" for="exampleRadios3">Disabled radio</label>
</div>
Inline

Group checkboxes or radios on the same horizontal row by adding .form-check-inline to any .form-check.

<div class="form-check form-check-inline">
  <input class="form-check-input" type="checkbox" id="inlineCheckbox1" value="option1">
  <label class="form-check-label" for="inlineCheckbox1">1</label>
</div>

<div class="form-check form-check-inline">
  <input class="form-check-input" type="checkbox" id="inlineCheckbox2" value="option2">
  <label class="form-check-label" for="inlineCheckbox2">2</label>
</div>

<div class="form-check form-check-inline">
  <input class="form-check-input" type="checkbox" id="inlineCheckbox3" value="option3" disabled>
  <label class="form-check-label" for="inlineCheckbox3">3 (disabled)</label>
</div>
<div class="form-check form-check-inline">
  <input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio1" value="option1">
  <label class="form-check-label" for="inlineRadio1">1</label>
</div>

<div class="form-check form-check-inline">
  <input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio2" value="option2">
  <label class="form-check-label" for="inlineRadio2">2</label>
</div>

<div class="form-check form-check-inline">
  <input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio3" value="option3" disabled>
  <label class="form-check-label" for="inlineRadio3">3 (disabled)</label>
</div>
Without labels

Add .position-static to inputs within .form-check that don’t have any label text. Remember to still provide some form of accessible name for assistive technologies (for instance, using aria-label).

<div class="form-check">
  <input class="form-check-input position-static" type="checkbox" id="blankCheckbox" value="option1" aria-label="...">
</div>

<div class="form-check">
  <input class="form-check-input position-static" type="radio" name="blankRadio" id="blankRadio1" value="option1" aria-label="...">
</div>

Layout

Since Bootstrap applies display: block and width: 100% to almost all our form controls, forms will by default stack vertically. Additional classes can be used to vary this layout on a per-form basis.

Form groups

The .form-group class is the easiest way to add some structure to forms. It provides a flexible class that encourages proper grouping of labels, controls, optional help text, and form validation messaging. By default it only applies margin-bottom, but it picks up additional styles in .form-inline as needed. Use it with <fieldset>s, <div>s, or nearly any other element.

<form>
  <div class="form-group">
    <label for="formGroupExampleInput">Example label</label>
    <input type="text" class="form-control" id="formGroupExampleInput" placeholder="Example input placeholder">
  </div>
  <div class="form-group">
    <label for="formGroupExampleInput2">Another label</label>
    <input type="text" class="form-control" id="formGroupExampleInput2" placeholder="Another input placeholder">
  </div>
</form>
Form grid

More complex forms can be built using our grid classes. Use these for form layouts that require multiple columns, varied widths, and additional alignment options.

<form>
  <div class="row">
    <div class="col">
      <input type="text" class="form-control" placeholder="First name">
    </div>
    <div class="col">
      <input type="text" class="form-control" placeholder="Last name">
    </div>
  </div>
</form>
Form row

You may also swap .row for .form-row, a variation of our standard grid row that overrides the default column gutters for tighter and more compact layouts.

<form>
  <div class="form-row">
    <div class="col">
      <input type="text" class="form-control" placeholder="First name">
    </div>
    <div class="col">
      <input type="text" class="form-control" placeholder="Last name">
    </div>
  </div>
</form>

More complex layouts can also be created with the grid system.

<form>
  <div class="form-row">
    <div class="form-group col-md-6">
      <label for="inputEmail4">Email</label>
      <input type="email" class="form-control" id="inputEmail4">
    </div>
    <div class="form-group col-md-6">
      <label for="inputPassword4">Password</label>
      <input type="password" class="form-control" id="inputPassword4">
    </div>
  </div>
  <div class="form-group">
    <label for="inputAddress">Address</label>
    <input type="text" class="form-control" id="inputAddress" placeholder="1234 Main St">
  </div>
  <div class="form-group">
    <label for="inputAddress2">Address 2</label>
    <input type="text" class="form-control" id="inputAddress2" placeholder="Apartment, studio, or floor">
  </div>
  <div class="form-row">
    <div class="form-group col-md-6">
      <label for="inputCity">City</label>
      <input type="text" class="form-control" id="inputCity">
    </div>
    <div class="form-group col-md-4">
      <label for="inputState">State</label>
      <select id="inputState" class="form-control">
        <option selected>Choose...</option>
        <option>...</option>
      </select>
    </div>
    <div class="form-group col-md-2">
      <label for="inputZip">Zip</label>
      <input type="text" class="form-control" id="inputZip">
    </div>
  </div>
  <div class="form-group">
    <div class="form-check">
      <input class="form-check-input" type="checkbox" id="gridCheck">
      <label class="form-check-label" for="gridCheck">Check me out</label>
    </div>
  </div>
  <button type="submit" class="btn btn-primary">Sign in</button>
</form>
Horizontal form

Create horizontal forms with the grid by adding the .row class to form groups and using the .col-*-* classes to specify the width of your labels and controls. Be sure to add .col-form-label to your <label>s as well so they’re vertically centered with their associated form controls.

At times, you maybe need to use margin or padding utilities to create that perfect alignment you need. For example, we’ve removed the padding-top on our stacked radio inputs label to better align the text baseline.

Horizontal form label sizing

Be sure to use .col-form-label-sm or .col-form-label-lg to your <label>s or <legend>s to correctly follow the size of .form-control-lg and .form-control-sm.

    <div class="col-sm-10">

Column sizing

As shown in the previous examples, our grid system allows you to place any number of .cols within a .row or .form-row. They’ll split the available width equally between them. You may also pick a subset of your columns to take up more or less space, while the remaining .cols equally split the rest, with specific column classes like .col-7.

<form>
  <div class="form-row">
    <div class="col-7">
      <input type="text" class="form-control" placeholder="City">
    </div>
    <div class="col">
      <input type="text" class="form-control" placeholder="State">
    </div>
    <div class="col">
      <input type="text" class="form-control" placeholder="Zip">
    </div>
  </div>
</form>
Auto-sizing

The example below uses a flexbox utility to vertically center the contents and changes .col to .col-auto so that your columns only take up as much space as needed. Put another way, the column sizes itself based on the contents.

@
<form>
  <div class="form-row align-items-center">
    <div class="col-auto">
      <label class="sr-only" for="inlineFormInput">Name</label>
      <input type="text" class="form-control mb-2" id="inlineFormInput" placeholder="Jane Doe">
    </div>
    <div class="col-auto">
      <label class="sr-only" for="inlineFormInputGroup">Username</label>
      <div class="input-group mb-2">
        <div class="input-group-prepend">
          <div class="input-group-text">@</div>
        </div>
        <input type="text" class="form-control" id="inlineFormInputGroup" placeholder="Username">
      </div>
    </div>
    <div class="col-auto">
      <div class="form-check mb-2">
        <input class="form-check-input" type="checkbox" id="autoSizingCheck">
        <label class="form-check-label" for="autoSizingCheck">Remember me</label>
      </div>
    </div>
    <div class="col-auto">
      <button type="submit" class="btn btn-primary mb-2">Submit</button>
    </div>
  </div>
</form>

You can then remix that once again with size-specific column classes.

@
<form>
  <div class="form-row align-items-center">
    <div class="col-sm-3 my-1">
      <label class="sr-only" for="inlineFormInputName">Name</label>
      <input type="text" class="form-control" id="inlineFormInputName" placeholder="Jane Doe">
    </div>
    <div class="col-sm-3 my-1">
      <label class="sr-only" for="inlineFormInputGroupUsername">Username</label>
      <div class="input-group">
        <div class="input-group-prepend">
          <div class="input-group-text">@</div>
        </div>
        <input type="text" class="form-control" id="inlineFormInputGroupUsername" placeholder="Username">
      </div>
    </div>
    <div class="col-auto my-1">
      <div class="form-check">
        <input class="form-check-input" type="checkbox" id="autoSizingCheck2">
        <label class="form-check-label" for="autoSizingCheck2">Remember me</label>
      </div>
    </div>
    <div class="col-auto my-1">
      <button type="submit" class="btn btn-primary">Submit</button>
    </div>
  </div>
</form>

And of course custom form controls are supported.

<form>
  <div class="form-row align-items-center">
    <div class="col-auto my-1">
      <label class="mr-sm-2 sr-only" for="inlineFormCustomSelect">Preference</label>
      <select class="custom-select mr-sm-2" id="inlineFormCustomSelect">
        <option selected>Choose...</option>
        <option value="1">One</option>
        <option value="2">Two</option>
        <option value="3">Three</option>
      </select>
    </div>
    <div class="col-auto my-1">
      <div class="custom-control custom-checkbox mr-sm-2">
        <input type="checkbox" class="custom-control-input" id="customControlAutosizing">
        <label class="custom-control-label" for="customControlAutosizing">Remember my preference</label>
      </div>
    </div>
    <div class="col-auto my-1">
      <button type="submit" class="btn btn-primary">Submit</button>
    </div>
  </div>
</form>
Inline forms

Use the .form-inline class to display a series of labels, form controls, and buttons on a single horizontal row. Form controls within inline forms vary slightly from their default states.

  • Controls are display: flex, collapsing any HTML white space and allowing you to provide alignment control with spacing and flexbox utilities.
  • Controls and input groups receive width: auto to override the Bootstrap default width: 100%.
  • Controls only appear inline in viewports that are at least 576px wide to account for narrow viewports on mobile devices.

You may need to manually address the width and alignment of individual form controls with spacing utilities (as shown below). Lastly, be sure to always include a <label> with each form control, even if you need to hide it from non-screenreader visitors with .sr-only.

@
<form class="form-inline">
  <label class="sr-only" for="inlineFormInputName2">Name</label>
  <input type="text" class="form-control mb-2 mr-sm-2" id="inlineFormInputName2" placeholder="Jane Doe">

  <label class="sr-only" for="inlineFormInputGroupUsername2">Username</label>
  <div class="input-group mb-2 mr-sm-2">
    <div class="input-group-prepend">
      <div class="input-group-text">@</div>
    </div>
    <input type="text" class="form-control" id="inlineFormInputGroupUsername2" placeholder="Username">
  </div>

  <div class="form-check mb-2 mr-sm-2">
    <input class="form-check-input" type="checkbox" id="inlineFormCheck">
    <label class="form-check-label" for="inlineFormCheck">Remember me</label>
  </div>

  <button type="submit" class="btn btn-primary mb-2">Submit</button>
</form>

Custom form controls and selects are also supported.

<form class="form-inline">
  <label class="my-1 mr-2" for="inlineFormCustomSelectPref">Preference</label>
  <select class="custom-select my-1 mr-sm-2" id="inlineFormCustomSelectPref">
    <option selected>Choose...</option>
    <option value="1">One</option>
    <option value="2">Two</option>
    <option value="3">Three</option>
  </select>

  <div class="custom-control custom-checkbox my-1 mr-sm-2">
    <input type="checkbox" class="custom-control-input" id="customControlInline">
    <label class="custom-control-label" for="customControlInline">Remember my preference</label>
  </div>

  <button type="submit" class="btn btn-primary my-1">Submit</button>
</form>

Help text

Block-level help text in forms can be created using .form-text (previously known as .help-block in v3). Inline help text can be flexibly implemented using any inline HTML element and utility classes like .text-muted.

Help text below inputs can be styled with .form-text. This class includes display: block and adds some top margin for easy spacing from the inputs above.

Your password must be 8-20 characters long, contain letters and numbers, and must not contain spaces, special characters, or emoji.
<label for="inputPassword5">Password</label>
<input type="password" id="inputPassword5" class="form-control" aria-describedby="passwordHelpBlock">
<small id="passwordHelpBlock" class="form-text text-muted">Your password must be 8-20 characters long, contain letters and numbers, and must not contain spaces, special characters, or emoji.</small>

Inline text can use any typical inline HTML element (be it a <small>, <span>, or something else) with nothing more than a utility class.

Must be 8-20 characters long.
<form class="form-inline">
  <div class="form-group">
    <label for="inputPassword6">Password</label>
    <input type="password" id="inputPassword6" class="form-control mx-sm-3" aria-describedby="passwordHelpInline">
    <small id="passwordHelpInline" class="text-muted">Must be 8-20 characters long.</small>
  </div>
</form>

Disabled forms

Add the disabled boolean attribute on an input to prevent user interactions and make it appear lighter.

<input class="form-control" id="disabledInput" type="text" placeholder="Disabled input here..." disabled>

Add the disabled attribute to a <fieldset> to disable all the controls within.

Disabled fieldset example
<form>
  <fieldset disabled>
    <legend>Disabled fieldset example</legend>
    <div class="form-group">
      <label for="disabledTextInput">Disabled input</label>
      <input type="text" id="disabledTextInput" class="form-control" placeholder="Disabled input">
    </div>
    <div class="form-group">
      <label for="disabledSelect">Disabled select menu</label>
      <select id="disabledSelect" class="form-control">
        <option>Disabled select</option>
      </select>
    </div>
    <div class="form-group">
      <div class="form-check">
        <input class="form-check-input" type="checkbox" id="disabledFieldsetCheck" disabled>
        <label class="form-check-label" for="disabledFieldsetCheck">Can't check this</label>
      </div>
    </div>
    <button type="submit" class="btn btn-primary">Submit</button>
  </fieldset>
</form>

Validation

Provide valuable, actionable feedback to your users with HTML5 form validation–available in all our supported browsers. Choose from the browser default validation feedback, or implement custom messages with our built-in classes and starter JavaScript.

How it works

Here’s how form validation works with Bootstrap:

  • HTML form validation is applied via CSS’s two pseudo-classes, :invalid and :valid. It applies to <input>, <select>, and <textarea> elements.
  • Bootstrap scopes the :invalid and :valid styles to parent .was-validated class, usually applied to the <form>. Otherwise, any required field without a value shows up as invalid on page load. This way, you may choose when to activate them (typically after form submission is attempted).
  • To reset the appearance of the form (for instance, in the case of dynamic form submissions using AJAX), remove the .was-validated class from the <form> again after submission.
  • As a fallback, .is-invalid and .is-valid classes may be used instead of the pseudo-classes for server side validation. They do not require a .was-validated parent class.
  • Due to constraints in how CSS works, we cannot (at present) apply styles to a <label> that comes before a form control in the DOM without the help of custom JavaScript.
  • All modern browsers support the constraint validation API, a series of JavaScript methods for validating form controls.
  • Feedback messages may utilize the browser defaults (different for each browser, and unstylable via CSS) or our custom feedback styles with additional HTML and CSS.
  • You may provide custom validity messages with setCustomValidity in JavaScript.

With that in mind, consider the following demos for our custom form validation styles, optional server side classes, and browser defaults.

Custom style

For custom Bootstrap form validation messages, you’ll need to add the novalidate boolean attribute to your <form>. This disables the browser default feedback tooltips, but still provides access to the form validation APIs in JavaScript. Try to submit the form below; our JavaScript will intercept the submit button and relay feedback to you. When attempting to submit, you’ll see the :invalid and :valid styles applied to your form controls.

Custom feedback styles apply custom colors, borders, focus styles, and background icons to better communicate feedback. Background icons for <select>s are only available with .custom-select, and not .form-control.

</script>
Browser defaults

Not interested in custom validation feedback messages or writing JavaScript to change form behaviors? All good, you can use the browser defaults. Try submitting the form below. Depending on your browser and OS, you’ll see a slightly different style of feedback.

While these feedback styles cannot be styled with CSS, you can still customize the feedback text through JavaScript.

<form>
  <div class="form-row">
    <div class="col-md-6 mb-3">
      <label for="validationDefault01">First name</label>
      <input type="text" class="form-control" id="validationDefault01" value="Mark" required>
    </div>
    <div class="col-md-6 mb-3">
      <label for="validationDefault02">Last name</label>

    <div class="form-check">
      <input class="form-check-input" type="checkbox" value="" id="invalidCheck2" required>
      <label class="form-check-label" for="invalidCheck2">Agree to terms and conditions</label>
    </div>
  </div>
  <button class="btn btn-primary" type="submit">Submit form</button>
</form>
Server side

We recommend using client-side validation, but in case you require server-side validation, you can indicate invalid and valid form fields with .is-invalid and .is-valid. Note that .invalid-feedback is also supported with these classes.

For invalid fields, ensure that the invalid feedback/error message is associated with the relevant form field using aria-describedby. This attribute allows more than one id to be referenced, in case the field already points to additional form text.

Tooltips

If your form layout allows it, you can swap the .{valid|invalid}-feedback classes for .{valid|invalid}-tooltip classes to display validation feedback in a styled tooltip. Be sure to have a parent with position: relative on it for tooltip positioning. In the example below, our column classes have this already, but your project may require an alternative setup.

    </div>
  </div>
  <button class="btn btn-primary" type="submit">Submit form</button>
</form>
Input group validation

To detect what elements need rounded corners inside an input group with validation, an input group requires an additional .has-validation class.

<div class="input-group has-validation">
  <div class="input-group-prepend">
    <span class="input-group-text">@</span>
  </div>
  <input type="text" class="form-control" required>
  <div class="invalid-feedback">Please choose a username.</div>
</div>
@
Please choose a username.

Custom forms

For even more customization and cross browser consistency, use our completely custom form elements to replace the browser defaults. They’re built on top of semantic and accessible markup, so they’re solid replacements for any default form control.

Checkboxes and radios

Each checkbox and radio <input> and <label> pairing is wrapped in a <div> to create our custom control. Structurally, this is the same approach as our default .form-check.

We use the sibling selector (~) for all our <input> states—like :checked—to properly style our custom form indicator. When combined with the .custom-control-label class, we can also style the text for each item based on the <input>’s state.

We hide the default <input> with opacity and use the .custom-control-label to build a new custom form indicator in its place with ::before and ::after. Unfortunately we can’t build a custom one from just the <input> because CSS’s content doesn’t work on that element.

In the checked states, we use base64 embedded SVG icons from Open Iconic. This provides us the best control for styling and positioning across browsers and devices.

Checkboxes
<div class="custom-control custom-checkbox">
  <input type="checkbox" class="custom-control-input" id="customCheck1">
  <label class="custom-control-label" for="customCheck1">Check this custom checkbox</label>
</div>

Custom checkboxes can also utilize the :indeterminate pseudo class when manually set via JavaScript (there is no available HTML attribute for specifying it).

<script>
  (function() {
    'use strict';

    $('.your-checkbox').prop('indeterminate', true);
  })();
</script>
Radios
<div class="custom-control custom-radio">
  <input type="radio" id="customRadio1" name="customRadio" class="custom-control-input">
  <label class="custom-control-label" for="customRadio1">Toggle this custom radio</label>
</div>

<div class="custom-control custom-radio">
  <input type="radio" id="customRadio2" name="customRadio" class="custom-control-input">
  <label class="custom-control-label" for="customRadio2">Or toggle this other custom radio</label>
</div>
Inline
<div class="custom-control custom-radio custom-control-inline">
  <input type="radio" id="customRadioInline1" name="customRadioInline" class="custom-control-input">
  <label class="custom-control-label" for="customRadioInline1">Toggle this custom radio</label>
</div>

<div class="custom-control custom-radio custom-control-inline">
  <input type="radio" id="customRadioInline2" name="customRadioInline" class="custom-control-input">
  <label class="custom-control-label" for="customRadioInline2">Or toggle this other custom radio</label>
</div>
Disabled

Custom checkboxes and radios can also be disabled. Add the disabled boolean attribute to the <input> and the custom indicator and label description will be automatically styled.

<div class="custom-control custom-checkbox">
  <input type="checkbox" class="custom-control-input" id="customCheckDisabled1" disabled>
  <label class="custom-control-label" for="customCheckDisabled1">Check this custom checkbox</label>
</div>

<div class="custom-control custom-radio">
  <input type="radio" name="radioDisabled" id="customRadioDisabled2" class="custom-control-input" disabled>
  <label class="custom-control-label" for="customRadioDisabled2">Toggle this custom radio</label>
</div>
Switches

A switch has the markup of a custom checkbox but uses the .custom-switch class to render a toggle switch. Switches also support the disabled attribute.

<div class="custom-control custom-switch">
  <input type="checkbox" class="custom-control-input" id="customSwitch1">
  <label class="custom-control-label" for="customSwitch1">Toggle this switch element</label>
</div>

<div class="custom-control custom-switch">
  <input type="checkbox" class="custom-control-input" disabled id="customSwitch2">
  <label class="custom-control-label" for="customSwitch2">Disabled switch element</label>
</div>
Select menu

Custom <select> menus need only a custom class, .custom-select to trigger the custom styles. Custom styles are limited to the <select>’s initial appearance and cannot modify the <option>s due to browser limitations.

<select class="custom-select">
  <option selected>Open this select menu</option>
  <option value="1">One</option>
  <option value="2">Two</option>
  <option value="3">Three</option>
</select>

You may also choose from small and large custom selects to match our similarly sized text inputs.

<select class="custom-select custom-select-lg mb-3">
  <option selected>Open this select menu</option>
  <option value="1">One</option>
  <option value="2">Two</option>
  <option value="3">Three</option>
</select>

<select class="custom-select custom-select-sm">
  <option selected>Open this select menu</option>
  <option value="1">One</option>
  <option value="2">Two</option>
  <option value="3">Three</option>
</select>

The multiple attribute is also supported:

<select class="custom-select" multiple>
  <option selected>Open this select menu</option>
  <option value="1">One</option>
  <option value="2">Two</option>
  <option value="3">Three</option>
</select>

As is the size attribute:

<select class="custom-select" size="3">
  <option selected>Open this select menu</option>
  <option value="1">One</option>
  <option value="2">Two</option>
  <option value="3">Three</option>
</select>
Range

Create custom <input type="range"> controls with .custom-range. The track (the background) and thumb (the value) are both styled to appear the same across browsers. As only IE and Firefox support “filling” their track from the left or right of the thumb as a means to visually indicate progress, we do not currently support it.

<label for="customRange1">Example range</label>
<input type="range" class="custom-range" id="customRange1">

Range inputs have implicit values for min and max0 and 100, respectively. You may specify new values for those using the min and max attributes.

<label for="customRange2">Example range</label>
<input type="range" class="custom-range" min="0" max="5" id="customRange2">

By default, range inputs “snap” to integer values. To change this, you can specify a step value. In the example below, we double the number of steps by using step="0.5".

<label for="customRange3">Example range</label>
<input type="range" class="custom-range" min="0" max="5" step="0.5" id="customRange3">
File browser

The file input is the most gnarly of the bunch and requires additional JavaScript if you’d like to hook them up with functional Choose file… and selected file name text.

<div class="custom-file">
  <input type="file" class="custom-file-input" id="customFile">
  <label class="custom-file-label" for="customFile">Choose file</label>
</div>

We hide the default file <input> via opacity and instead style the <label>. The button is generated and positioned with ::after. Lastly, we declare a width and height on the <input> for proper spacing for surrounding content.

Translating or customizing the strings with HTML

Bootstrap also provides a way to translate the “Browse” text in HTML with the data-browse attribute which can be added to the custom input label (example in Dutch):

<div class="custom-file">
  <input type="file" class="custom-file-input" id="customFileLangHTML">
  <label class="custom-file-label" for="customFileLangHTML" data-browse="Bestand kiezen">Voeg je document toe</label>
</div>

Input group

Easily extend form controls by adding text, buttons, or button groups on either side of textual inputs, custom selects, and custom file inputs.

Basic examples

Place one add-on or button on either side of an input. You may also place one on both sides of an input. Remember to place <label>s outside the input group.

@
@example.com
https://example.com/users/
$
.00
With textarea
<div class="input-group mb-3">
  <div class="input-group-prepend">
    <span class="input-group-text" id="basic-addon1">@</span>
  </div>
  <input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="basic-addon1">
</div>

<div class="input-group mb-3">
  <input type="text" class="form-control" placeholder="Recipient's username" aria-label="Recipient's username" aria-describedby="basic-addon2">
  <div class="input-group-append">
    <span class="input-group-text" id="basic-addon2">@example.com</span>
  </div>
</div>

<label for="basic-url">Your vanity URL</label>
<div class="input-group mb-3">
  <div class="input-group-prepend">
    <span class="input-group-text" id="basic-addon3">https://example.com/users/</span>
  </div>
  <input type="text" class="form-control" id="basic-url" aria-describedby="basic-addon3">
</div>

<div class="input-group mb-3">
  <div class="input-group-prepend">
    <span class="input-group-text">$</span>
  </div>
  <input type="text" class="form-control" aria-label="Amount (to the nearest dollar)">
  <div class="input-group-append">
    <span class="input-group-text">.00</span>
  </div>
</div>

<div class="input-group">
  <div class="input-group-prepend">
    <span class="input-group-text">With textarea</span>
  </div>
  <textarea class="form-control" aria-label="With textarea"></textarea>
</div>

Wrapping

Input groups wrap by default via flex-wrap: wrap in order to accommodate custom form field validation within an input group. You may disable this with .flex-nowrap.

@
<div class="input-group flex-nowrap">
  <div class="input-group-prepend">
    <span class="input-group-text" id="addon-wrapping">@</span>
  </div>
  <input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="addon-wrapping">
</div>

Sizing

Add the relative form sizing classes to the .input-group itself and contents within will automatically resize—no need for repeating the form control size classes on each element.

Sizing on the individual input group elements isn’t supported.

Small
Default
Large
<div class="input-group input-group-sm mb-3">
  <div class="input-group-prepend">
    <span class="input-group-text" id="inputGroup-sizing-sm">Small</span>
  </div>
  <input type="text" class="form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-sm">
</div>

<div class="input-group mb-3">
  <div class="input-group-prepend">
    <span class="input-group-text" id="inputGroup-sizing-default">Default</span>
  </div>
  <input type="text" class="form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-default">
</div>

<div class="input-group input-group-lg">
  <div class="input-group-prepend">
    <span class="input-group-text" id="inputGroup-sizing-lg">Large</span>
  </div>
  <input type="text" class="form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-lg">
</div>

Checkboxes and radios

Place any checkbox or radio option within an input group’s addon instead of text.

<div class="input-group mb-3">
  <div class="input-group-prepend">
    <div class="input-group-text">
      <input type="checkbox" aria-label="Checkbox for following text input">
    </div>
  </div>
  <input type="text" class="form-control" aria-label="Text input with checkbox">
</div>

<div class="input-group">
  <div class="input-group-prepend">
    <div class="input-group-text">
      <input type="radio" aria-label="Radio button for following text input">
    </div>
  </div>
  <input type="text" class="form-control" aria-label="Text input with radio button">
</div>

Multiple inputs

While multiple <input>s are supported visually, validation styles are only available for input groups with a single <input>.

First and last name
<div class="input-group">
  <div class="input-group-prepend">
    <span class="input-group-text">First and last name</span>
  </div>
  <input type="text" aria-label="First name" class="form-control">
  <input type="text" aria-label="Last name" class="form-control">
</div>

Multiple addons

Multiple add-ons are supported and can be mixed with checkbox and radio input versions.

Jumbotron

Lightweight, flexible component for showcasing hero unit style content.

A lightweight, flexible component that can optionally extend the entire viewport to showcase key marketing messages on your site.

Hello, world!

This is a simple hero unit, a simple jumbotron-style component for calling extra attention to featured content or information.


It uses utility classes for typography and spacing to space content out within the larger container.

<div class="jumbotron">
  <h1 class="display-4">Hello, world!</h1>
  <p class="lead">This is a simple hero unit, a simple jumbotron-style component for calling extra attention to featured content or information.</p>
  <hr class="my-4">
  <p>It uses utility classes for typography and spacing to space content out within the larger container.</p>
  <a class="btn btn-primary btn-lg" href="#" role="button">Learn more</a>
</div>

To make the jumbotron full width, and without rounded corners, add the .jumbotron-fluid modifier class and add a .container or .container-fluid within.

Fluid jumbotron

This is a modified jumbotron that occupies the entire horizontal space of its parent.

<div class="jumbotron jumbotron-fluid">

List group

List groups are a flexible and powerful component for displaying a series of content. Modify and extend them to support just about any content within.

Basic examples

The most basic list group is an unordered list with list items and the proper classes. Build upon it with the options that follow, or with your own CSS as needed.

  • Cras justo odio
  • Dapibus ac facilisis in
  • Morbi leo risus
  • Porta ac consectetur ac
  • Vestibulum at eros
<ul class="list-group">
  <li class="list-group-item">Cras justo odio</li>
  <li class="list-group-item">Dapibus ac facilisis in</li>
  <li class="list-group-item">Morbi leo risus</li>
  <li class="list-group-item">Porta ac consectetur ac</li>
  <li class="list-group-item">Vestibulum at eros</li>
</ul>

Active items

Add .active to a .list-group-item to indicate the current active selection.

  • Cras justo odio
  • Dapibus ac facilisis in
  • Morbi leo risus
  • Porta ac consectetur ac
  • Vestibulum at eros
<ul class="list-group">
  <li class="list-group-item active">Cras justo odio</li>
  <li class="list-group-item">Dapibus ac facilisis in</li>
  <li class="list-group-item">Morbi leo risus</li>
  <li class="list-group-item">Porta ac consectetur ac</li>
  <li class="list-group-item">Vestibulum at eros</li>
</ul>

Disabled items

Add .disabled to a .list-group-item to make it appear disabled. Note that some elements with .disabled will also require custom JavaScript to fully disable their click events (e.g., links).

  • Cras justo odio
  • Dapibus ac facilisis in
  • Morbi leo risus
  • Porta ac consectetur ac
  • Vestibulum at eros
<ul class="list-group">
  <li class="list-group-item disabled" aria-disabled="true">Cras justo odio</li>
  <li class="list-group-item">Dapibus ac facilisis in</li>
  <li class="list-group-item">Morbi leo risus</li>
  <li class="list-group-item">Porta ac consectetur ac</li>
  <li class="list-group-item">Vestibulum at eros</li>
</ul>

Flush

Add .list-group-flush to remove some borders and rounded corners to render list group items edge-to-edge in a parent container (e.g., cards).

  • Cras justo odio
  • Dapibus ac facilisis in
  • Morbi leo risus
  • Porta ac consectetur ac
  • Vestibulum at eros
<ul class="list-group list-group-flush">
  <li class="list-group-item">Cras justo odio</li>
  <li class="list-group-item">Dapibus ac facilisis in</li>
  <li class="list-group-item">Morbi leo risus</li>
  <li class="list-group-item">Porta ac consectetur ac</li>
  <li class="list-group-item">Vestibulum at eros</li>
</ul>

Horizontal

Add .list-group-horizontal to change the layout of list group items from vertical to horizontal across all breakpoints. Alternatively, choose a responsive variant .list-group-horizontal-{sm|md|lg|xl} to make a list group horizontal starting at that breakpoint’s min-width. Currently horizontal list groups cannot be combined with flush list groups.

ProTip: Want equal-width list group items when horizontal? Add .flex-fill to each list group item.

</ul>

Contextual classes

Use contextual classes to style list items with a stateful background and color.

  • Dapibus ac facilisis in
  • A simple primary list group item
  • A simple secondary list group item
  • A simple success list group item
  • A simple danger list group item
  • A simple warning list group item
  • A simple info list group item
  • A simple light list group item
  • A simple dark list group item
<ul class="list-group">
  <li class="list-group-item">Dapibus ac facilisis in</li>

  <li class="list-group-item list-group-item-primary">A simple primary list group item</li>
  <li class="list-group-item list-group-item-secondary">A simple secondary list group item</li>
  <li class="list-group-item list-group-item-success">A simple success list group item</li>
  <li class="list-group-item list-group-item-danger">A simple danger list group item</li>
  <li class="list-group-item list-group-item-warning">A simple warning list group item</li>
  <li class="list-group-item list-group-item-info">A simple info list group item</li>
  <li class="list-group-item list-group-item-light">A simple light list group item</li>
  <li class="list-group-item list-group-item-dark">A simple dark list group item</li>
</ul>

Contextual classes also work with .list-group-item-action. Note the addition of the hover styles here not present in the previous example. Also supported is the .active state; apply it to indicate an active selection on a contextual list group item.

<div class="list-group">
  <a href="#" class="list-group-item list-group-item-action">Dapibus ac facilisis in</a>

  <a href="#" class="list-group-item list-group-item-action list-group-item-primary">A simple primary list group item</a>
  <a href="#" class="list-group-item list-group-item-action list-group-item-secondary">A simple secondary list group item</a>
  <a href="#" class="list-group-item list-group-item-action list-group-item-success">A simple success list group item</a>
  <a href="#" class="list-group-item list-group-item-action list-group-item-danger">A simple danger list group item</a>
  <a href="#" class="list-group-item list-group-item-action list-group-item-warning">A simple warning list group item</a>
  <a href="#" class="list-group-item list-group-item-action list-group-item-info">A simple info list group item</a>
  <a href="#" class="list-group-item list-group-item-action list-group-item-light">A simple light list group item</a>
  <a href="#" class="list-group-item list-group-item-action list-group-item-dark">A simple dark list group item</a>
</div>

With badges

Add badges to any list group item to show unread counts, activity, and more with the help of some utilities.

  • Cras justo odio14
  • Dapibus ac facilisis in2
  • Morbi leo risus1
<ul class="list-group">
  <li class="list-group-item d-flex justify-content-between align-items-center">Cras justo odio<span class="badge badge-primary badge-pill">14</span></li>
  <li class="list-group-item d-flex justify-content-between align-items-center">Dapibus ac facilisis in<span class="badge badge-primary badge-pill">2</span></li>
  <li class="list-group-item d-flex justify-content-between align-items-center">Morbi leo risus<span class="badge badge-primary badge-pill">1</span></li>
</ul>

Custom content

Add nearly any HTML within, even for linked list groups like the one below, with the help of flexbox utilities.

<div class="list-group">
  <a href="#" class="list-group-item list-group-item-action active">
    <div class="d-flex w-100 justify-content-between">
      <h5>List group item heading</h5>
      <small>3 days ago</small>
    </div>
    <p>Donec id elit non mi porta gravida at eget metus. Maecenas sed diam eget risus varius blandit.</p>
    <small>Donec id elit non mi porta.</small>
  </a>
  <a href="#" class="list-group-item list-group-item-action">
    <div class="d-flex w-100 justify-content-between">
      <h5>List group item heading</h5>
      <small>3 days ago</small>
    </div>
    <p>Donec id elit non mi porta gravida at eget metus. Maecenas sed diam eget risus varius blandit.</p>
    <small>Donec id elit non mi porta.</small>
  </a>
  <a href="#" class="list-group-item list-group-item-action">
    <div class="d-flex w-100 justify-content-between">
      <h5>List group item heading</h5>
      <small>3 days ago</small>
    </div>
    <p>Donec id elit non mi porta gravida at eget metus. Maecenas sed diam eget risus varius blandit.</p>
    <small>Donec id elit non mi porta.</small>
  </a>
</div>

JavaScript behavior

Use the tab JavaScript plugin—include it individually or through the compiled bootstrap.js file—to extend our list group to create tabbable panes of local content.

<div class="row">
  <div class="col-4">
    <div class="list-group" id="list-tab" role="tablist">
      <a class="list-group-item list-group-item-action active" id="list-home-list" data-toggle="list" href="#list-home" role="tab" aria-controls="home">Home</a>
      <a class="list-group-item list-group-item-action" id="list-profile-list" data-toggle="list" href="#list-profile" role="tab" aria-controls="profile">Profile</a>
      <a class="list-group-item list-group-item-action" id="list-messages-list" data-toggle="list" href="#list-messages" role="tab" aria-controls="messages">Messages</a>
      <a class="list-group-item list-group-item-action" id="list-settings-list" data-toggle="list" href="#list-settings" role="tab" aria-controls="settings">Settings</a>
    </div>
  </div>
  <div class="col-8">
    <div class="tab-content" id="nav-tabContent">

Media object

Documentation and examples for Bootstrap’s media object to construct highly repetitive components like blog comments, tweets, and the like.

Example

The media object helps build complex and repetitive components where some media is positioned alongside content that doesn’t wrap around said media. Plus, it does this with only two required classes thanks to flexbox.

Below is an example of a single media object. Only two classes are required—the wrapping .media and the .media-body around your content. Optional padding and margin can be controlled through spacing utilities.

Media heading

Will you do the same for me? It's time to face the music I'm no longer your muse. Heard it's beautiful, be the judge and my girls gonna take a vote. I can feel a phoenix inside of me. Heaven is jealous of our love, angels are crying from up above. Yeah, you take me to utopia.

<div class="media">
  <img src="..." class="mr-3" alt="...">
  <div class="media-body">
    <h5>Media heading</h5>

  </div>
</div>

Nesting

Media objects can be infinitely nested, though we suggest you stop at some point. Place nested .media within the .media-body of a parent media object.

Standing on the frontline when the bombs start to fall. Heaven is jealous of our love, angels are crying from up above. Can't replace you with a million rings. Boy, when you're with me I'll give you a taste. There’s no going back. Before you met me I was alright but things were kinda heavy. Heavy is the head that wears the crown.

Greetings loved ones let's take a journey. Yes, we make angels cry, raining down on earth from up above. Give you something good to celebrate. I used to bite my tongue and hold my breath. I'm ma get your heart racing in my skin-tight jeans. As I march alone to a different beat. Summer after high school when we first met. You're so hypnotizing, could you be the devil? Could you be an angel? It's time to bring out the big balloons. Thought that I was the exception. Bikinis, zucchinis, Martinis, no weenies.

Alignment

Media in a media object can be aligned with flexbox utilities to the top (default), middle, or end of your .media-body content.

I’m gon’ put her in a coma. You give a hundred reasons why, and you say you're really gonna try. So I sat quietly, agreed politely. Suiting up for my crowning battle. And on my 18th Birthday we got matching tattoos. So très chic, yeah, she's a classic. I am ready for the road less traveled.

I'm walking on air (tonight). But down to earth. You're original, cannot be replaced. But in another life I would be your girl. We drove to Cali and got drunk on the beach. We can dance, until we die, you and I, will be young forever. Saw you downtown singing the Blues.

Order

Change the order of content in media objects by modifying the HTML itself, or by adding some custom flexbox CSS to set the order property (to an integer of your choosing).

I know there will be sacrifice but that's the price. Are you brave enough to let me see your peacock? Be your teenage dream tonight. Uh-huh, I see you. There’s no going back. Yeah, we maxed our credit cards and got kicked out of the bar. So let me get you in your birthday suit. You may fall in love when you meet her. Had the world in the palm of your hands. Don't let the greatness get you down, oh, oh yeah. Now we talking astrology, getting our nails did, all Japanese-y. Make me your Aphrodite.

Media list

Because the media object has so few structural requirements, you can also use these classes on list HTML elements. On your <ul> or <ol>, add the .list-unstyled to remove any browser default list styles, and then apply .media to your <li>s. As always, use spacing utilities wherever needed to fine tune.

Popovers

Documentation and examples for adding Bootstrap popovers, like those found in iOS, to any element on your site.

Example

<button type="button" class="btn btn-lg btn-primary" data-toggle="popover" title="Popover title" data-content="And here's some amazing content. It's very engaging. Right?">Click to toggle popover</button>
Four directions

Four options are available: top, right, bottom, and left aligned.

<button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="top" data-content="Top popover">Popover on top</button>
<button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="right" data-content="Right popover">Popover on right</button>
<button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="bottom" data-content="Bottom popover">Popover on bottom</button>
<button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="left" data-content="Left popover">Popover on left</button>
Dismiss on next click

Use the focus trigger to dismiss popovers on the user’s next click of a different element than the toggle element.

<a tabindex="0" class="btn btn-lg btn-danger" role="button" data-toggle="popover" data-trigger="focus" title="Dismissible popover" data-content="And here's some amazing content. It's very engaging. Right?">Dismissible popover</a>
<script>
  (function() {
    'use strict';

    $('.popover-dismiss').popover({
      trigger: 'focus'
    });
  })();
</script>
Disabled elements

Elements with the disabled attribute aren’t interactive, meaning users cannot hover or click them to trigger a popover (or tooltip). As a workaround, you’ll want to trigger the popover from a wrapper <div> or <span> and override the pointer-events on the disabled element.

For disabled popover triggers, you may also prefer data-trigger="hover" so that the popover appears as immediate visual feedback to your users as they may not expect to click on a disabled element.

<span class="d-inline-block" data-toggle="popover" data-content="Disabled popover">
  <button class="btn btn-primary" style="pointer-events: none;" type="button" disabled>Disabled button</button>
</span>

Progress

Documentation and examples for using Bootstrap custom progress bars featuring support for stacked bars, animated backgrounds, and text labels.

How it works

Progress components are built with two HTML elements, some CSS to set the width, and a few attributes. We don’t use the HTML5 <progress> element, ensuring you can stack progress bars, animate them, and place text labels over them.

  • We use the .progress as a wrapper to indicate the max value of the progress bar.
  • We use the inner .progress-bar to indicate the progress so far.
  • The .progress-bar requires an inline style, utility class, or custom CSS to set their width.
  • The .progress-bar also requires some role and aria attributes to make it accessible.

Put that all together, and you have the following examples.

<div class="progress">
  <div class="progress-bar" role="progressbar" aria-valuenow="0" aria-valuemin="0" aria-valuemax="100"></div>
</div>

<div class="progress">
  <div class="progress-bar" role="progressbar" style="width: 25%" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
</div>

<div class="progress">
  <div class="progress-bar" role="progressbar" style="width: 50%" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100"></div>
</div>

<div class="progress">
  <div class="progress-bar" role="progressbar" style="width: 75%" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100"></div>
</div>

<div class="progress">
  <div class="progress-bar" role="progressbar" style="width: 100%" aria-valuenow="100" aria-valuemin="0" aria-valuemax="100"></div>
</div>

Bootstrap provides a handful of utilities for setting width. Depending on your needs, these may help with quickly configuring progress.

<div class="progress">
  <div class="progress-bar w-75" role="progressbar" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100"></div>
</div>

Labels

Add labels to your progress bars by placing text within the .progress-bar.

25%
<div class="progress">
  <div class="progress-bar" role="progressbar" style="width: 25%;" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100">25%</div>
</div>

Height

We only set a height value on the .progress, so if you change that value the inner .progress-bar will automatically resize accordingly.

<div class="progress" style="height: 1px;">
  <div class="progress-bar" role="progressbar" style="width: 25%;" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
</div>

<div class="progress" style="height: 20px;">
  <div class="progress-bar" role="progressbar" style="width: 25%;" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
</div>

Backgrounds

Use background utility classes to change the appearance of individual progress bars.

<div class="progress">
  <div class="progress-bar bg-success" role="progressbar" style="width: 25%" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
</div>

<div class="progress">
  <div class="progress-bar bg-info" role="progressbar" style="width: 50%" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100"></div>
</div>

<div class="progress">
  <div class="progress-bar bg-warning" role="progressbar" style="width: 75%" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100"></div>
</div>

<div class="progress">
  <div class="progress-bar bg-danger" role="progressbar" style="width: 100%" aria-valuenow="100" aria-valuemin="0" aria-valuemax="100"></div>
</div>

Multiple bars

Include multiple progress bars in a progress component if you need.

<div class="progress">
  <div class="progress-bar" role="progressbar" style="width: 15%" aria-valuenow="15" aria-valuemin="0" aria-valuemax="100"></div>
  <div class="progress-bar bg-success" role="progressbar" style="width: 30%" aria-valuenow="30" aria-valuemin="0" aria-valuemax="100"></div>
  <div class="progress-bar bg-info" role="progressbar" style="width: 20%" aria-valuenow="20" aria-valuemin="0" aria-valuemax="100"></div>
</div>

Striped

Add .progress-bar-striped to any .progress-bar to apply a stripe via CSS gradient over the progress bar’s background color.

<div class="progress">
  <div class="progress-bar progress-bar-striped" role="progressbar" style="width: 10%" aria-valuenow="10" aria-valuemin="0" aria-valuemax="100"></div>
</div>

<div class="progress">
  <div class="progress-bar progress-bar-striped bg-success" role="progressbar" style="width: 25%" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"></div>
</div>

<div class="progress">
  <div class="progress-bar progress-bar-striped bg-info" role="progressbar" style="width: 50%" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100"></div>
</div>

<div class="progress">
  <div class="progress-bar progress-bar-striped bg-warning" role="progressbar" style="width: 75%" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100"></div>
</div>

<div class="progress">
  <div class="progress-bar progress-bar-striped bg-danger" role="progressbar" style="width: 100%" aria-valuenow="100" aria-valuemin="0" aria-valuemax="100"></div>
</div>

Animated stripes

The striped gradient can also be animated. Add .progress-bar-animated to .progress-bar to animate the stripes right to left via CSS3 animations.

<div class="progress">
  <div class="progress-bar progress-bar-striped progress-bar-animated" role="progressbar" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100" style="width: 75%"></div>
</div>

Scrollspy

Automatically update Bootstrap navigation or list group components based on scroll position to indicate which link is currently active in the viewport.

How it works

Scrollspy has a few requirements to function properly:

  • If you’re building our JavaScript from source, it requires util.js.
  • It must be used on a Bootstrap nav component or list group.
  • Scrollspy requires position: relative; on the element you’re spying on, usually the <body>.
  • When spying on elements other than the <body>, be sure to have a height set and overflow-y: scroll; applied.
  • Anchors (<a>) are required and must point to an element with that id.

When successfully implemented, your nav or list group will update accordingly, moving the .active class from one item to the next based on their associated targets.

Example in navbar

Scroll the area below the navbar and watch the active class change. The dropdown items will be highlighted as well.

@fat

Placeholder content for the scrollspy example. You got the finest architecture. Passport stamps, she's cosmopolitan. Fine, fresh, fierce, we got it on lock. Never planned that one day I'd be losing you. She eats your heart out. Your kiss is cosmic, every move is magic. I mean the ones, I mean like she's the one. Greetings loved ones let's take a journey. Just own the night like the 4th of July! But you'd rather get wasted.

@mdo

Placeholder content for the scrollspy example. 'Cause she's the muse and the artist. (This is how we do) So you wanna play with magic. So just be sure before you give it all to me. I'm walking, I'm walking on air (tonight). Skip the talk, heard it all, time to walk the walk.

one

Placeholder content for the scrollspy example. Takes you miles high, so high, 'cause she’s got that one international smile. There's a stranger in my bed, there's a pounding in my head. Oh, no. In another life I would make you stay. ‘Cause I, I’m capable of anything. Suiting up for my crowning battle. Used to steal your parents' liquor and climb to the roof. Tone, tan fit and ready, turn it up cause its gettin' heavy. Her love is like a drug. I guess that I forgot I had a choice.

two

Placeholder content for the scrollspy example. It's time to bring out the big balloons. I'm walking, I'm walking on air (tonight). Yeah, we maxed our credit cards and got kicked out of the bar. Yo, shout out to all you kids, buying bottle service, with your rent money. I'm ma get your heart racing in my skin-tight jeans. If you get the chance you better keep her. Yo, shout out to all you kids, buying bottle service, with your rent money.

three

Placeholder content for the scrollspy example. If you wanna dance, if you want it all, you know that I'm the girl that you should call. Walk through the storm I would. So let me get you in your birthday suit. The one that got away. Last Friday night, yeah I think we broke the law, always say we're gonna stop. 'Cause she's a little bit of Yoko, And she's a little bit of 'Oh no'. I want the jaw droppin', eye poppin', head turnin', body shockin'. Yeah, we maxed our credit cards and got kicked out of the bar.

And some more placeholder content, for good measure.

<nav id="navbar-example2" class="navbar navbar-light bg-light">
  <a class="navbar-brand" href="#">Navbar</a>
  <ul class="nav nav-pills">
    <li class="nav-item"><a class="nav-link" href="#fat">@fat</a></li>
    <li class="nav-item"><a class="nav-link" href="#mdo">@mdo</a></li>
    <li class="nav-item dropdown">
      <a class="nav-link dropdown-toggle" data-toggle="dropdown" href="#" role="button" aria-haspopup="true" aria-expanded="false">Dropdown</a>
      <div class="dropdown-menu">
        <a class="dropdown-item" href="#one">one</a>
        <a class="dropdown-item" href="#two">two</a>
        <div role="separator" class="dropdown-divider"></div>
        <a class="dropdown-item" href="#three">three</a>
      </div>
    </li>
  </ul>
</nav>

<div data-spy="scroll" data-target="#navbar-example2" data-offset="0">

  <h4 id="two">two</h4>
  <p>...</p>
  <h4 id="three">three</h4>
  <p>...</p>
</div>

Example with nested nav

Scrollspy also works with nested .navs. If a nested .nav is .active, its parents will also be .active. Scroll the area next to the navbar and watch the active class change.

Spinners

Indicate the loading state of a component or page with Bootstrap spinners, built entirely with HTML, CSS, and no JavaScript.

About

Bootstrap “spinners” can be used to show the loading state in your projects. They’re built only with HTML and CSS, meaning you don’t need any JavaScript to create them. You will, however, need some custom JavaScript to toggle their visibility. Their appearance, alignment, and sizing can be easily customized with our amazing utility classes.

For accessibility purposes, each loader here includes role="status" and a nested <span class="sr-only">Loading...</span>.

Border spinner

Use the border spinners for a lightweight loading indicator.

Loading...
<div class="spinner-border" role="status">
  <span class="sr-only">Loading...</span>
</div>
Colors

The border spinner uses currentColor for its border-color, meaning you can customize the color with text color utilities. You can use any of our text color utilities on the standard spinner.

Loading...
Loading...
Loading...
Loading...
Loading...
Loading...
Loading...
Loading...
<div class="spinner-border text-primary" role="status">
  <span class="sr-only">Loading...</span>
</div>

<div class="spinner-border text-secondary" role="status">
  <span class="sr-only">Loading...</span>
</div>

<div class="spinner-border text-success" role="status">
  <span class="sr-only">Loading...</span>
</div>

<div class="spinner-border text-danger" role="status">
  <span class="sr-only">Loading...</span>
</div>

<div class="spinner-border text-warning" role="status">
  <span class="sr-only">Loading...</span>
</div>

<div class="spinner-border text-info" role="status">
  <span class="sr-only">Loading...</span>
</div>

<div class="spinner-border text-light" role="status">
  <span class="sr-only">Loading...</span>
</div>

<div class="spinner-border text-dark" role="status">
  <span class="sr-only">Loading...</span>
</div>

Growing spinner

If you don’t fancy a border spinner, switch to the grow spinner. While it doesn’t technically spin, it does repeatedly grow!

Loading...
<div class="spinner-grow" role="status">
  <span class="sr-only">Loading...</span>
</div>

Once again, this spinner is built with currentColor, so you can easily change its appearance with text color utilities. Here it is in blue, along with the supported variants.

<div class="spinner-grow text-primary" role="status">

  <span class="sr-only">Loading...</span>
</div>

<div class="spinner-grow text-success" role="status">
  <span class="sr-only">Loading...</span>
</div>

<div class="spinner-grow text-danger" role="status">
  <span class="sr-only">Loading...</span>
</div>

<div class="spinner-grow text-warning" role="status">
  <span class="sr-only">Loading...</span>
</div>

<div class="spinner-grow text-info" role="status">
  <span class="sr-only">Loading...</span>
</div>

<div class="spinner-grow text-light" role="status">
  <span class="sr-only">Loading...</span>
</div>

<div class="spinner-grow text-dark" role="status">
  <span class="sr-only">Loading...</span>
</div>

Alignment

Spinners in Bootstrap are built with rems, currentColor, and display: inline-flex. This means they can easily be resized, recolored, and quickly aligned.

Margin

Use margin utilities like .m-5 for easy spacing.

Loading...
<div class="spinner-border m-5" role="status">
  <span class="sr-only">Loading...</span>
</div>
Placement

Use flexbox utilities, float utilities, or text alignment utilities to place spinners exactly where you need them in any situation.

Flex
Loading...
<div class="d-flex justify-content-center">
  <div class="spinner-border" role="status">
    <span class="sr-only">Loading...</span>
  </div>
</div>
Loading...
<div class="d-flex align-items-center">
  <strong>Loading...</strong>
  <div class="spinner-border ml-auto" role="status" aria-hidden="true"></div>
</div>
Floats
Loading...
<div class="clearfix">
  <div class="spinner-border float-right" role="status">
    <span class="sr-only">Loading...</span>
  </div>
</div>
Text align
Loading...
<div class="text-center">
  <div class="spinner-border" role="status">
    <span class="sr-only">Loading...</span>
  </div>
</div>
Size

Add .spinner-border-sm and .spinner-grow-sm to make a smaller spinner that can quickly be used within other components.

Loading...
Loading...
<div class="spinner-border spinner-border-sm" role="status">
  <span class="sr-only">Loading...</span>
</div>

<div class="spinner-grow spinner-grow-sm" role="status">
  <span class="sr-only">Loading...</span>
</div>

Or, use custom CSS or inline styles to change the dimensions as needed.

Loading...
Loading...
<div class="spinner-border" style="width: 3rem; height: 3rem;" role="status">
  <span class="sr-only">Loading...</span>
</div>

<div class="spinner-grow" style="width: 3rem; height: 3rem;" role="status">
  <span class="sr-only">Loading...</span>
</div>
Buttons

Use spinners within buttons to indicate an action is currently processing or taking place. You may also swap the text out of the spinner element and utilize button text as needed.

<button class="btn btn-primary" type="button" disabled>
  <span class="spinner-border spinner-border-sm" role="status" aria-hidden="true"></span>
  <span class="sr-only">Loading...</span>
</button>

<button class="btn btn-primary" type="button" disabled>
  <span class="spinner-border spinner-border-sm" role="status" aria-hidden="true"></span>
  Loading...
</button>
<button class="btn btn-primary" type="button" disabled>
  <span class="spinner-grow spinner-grow-sm" role="status" aria-hidden="true"></span>
  <span class="sr-only">Loading...</span>
</button>

<button class="btn btn-primary" type="button" disabled>
  <span class="spinner-grow spinner-grow-sm" role="status" aria-hidden="true"></span>
  Loading...
</button>

Toasts

Push notifications to your visitors with a toast, a lightweight and easily customizable alert message.

Toasts are lightweight notifications designed to mimic the push notifications that have been popularized by mobile and desktop operating systems. They’re built with flexbox, so they’re easy to align and position.

Examples

Basic

To encourage extensible and predictable toasts, we recommend a header and body. Toast headers use display: flex, allowing easy alignment of content thanks to our margin and flexbox utilities.

Toasts are as flexible as you need and have very little required markup. At a minimum, we require a single element to contain your “toasted” content and strongly encourage a dismiss button.

<div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
  <div class="toast-header">
    <img src="..." class="rounded mr-2" alt="...">
    <strong class="mr-auto">Bootstrap</strong>
    <small class="mt-2">11 mins ago</small>
    <button type="button" class="ml-2 mt-1 close" data-dismiss="toast" aria-label="Close"><span aria-hidden="true">&times;</span></button>
  </div>
  <div class="toast-body">Hello, world! This is a toast message.</div>
</div>
Live

Click the button the below to show as toast (positioning with our utilities in the lower right corner) that has been hidden by default with .hide.

<button type="button" class="btn btn-primary" id="liveToastBtn">Show live toast</button>

<div class="position-fixed bottom-0 right-0 p-3" style="z-index: 5; right: 0; bottom: 0;">
  <div id="liveToast" class="toast hide" role="alert" aria-live="assertive" aria-atomic="true" data-delay="2000">
    <div class="toast-header">
      <img src="..." class="rounded mr-2" alt="...">
      <strong class="mr-auto">Bootstrap</strong>
      <small class="mt-2">11 mins ago</small>
      <button type="button" class="ml-2 mt-1 close" data-dismiss="toast" aria-label="Close"><span aria-hidden="true">&times;</span></button>
    </div>
    <div class="toast-body">Hello, world! This is a toast message.</div>
  </div>
</div>
Translucent

Toasts are slightly translucent, too, so they blend over whatever they might appear over. For browsers that support the backdrop-filter CSS property, we’ll also attempt to blur the elements under a toast.

<div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
  <div class="toast-header">
    <img src="..." class="rounded mr-2" alt="...">
    <strong class="mr-auto">Bootstrap</strong>
    <small class="mt-2">11 mins ago</small>
    <button type="button" class="ml-2 mt-1 close" data-dismiss="toast" aria-label="Close"><span aria-hidden="true">&times;</span></button>
  </div>
  <div class="toast-body">Hello, world! This is a toast message.</div>
</div>
Stacking

When you have multiple toasts, we default to vertically stacking them in a readable manner.

<div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
  <div class="toast-header">
    <img src="..." class="rounded mr-2" alt="...">
    <strong class="mr-auto">Bootstrap</strong>
    <small class="mt-2">just now</small>
    <button type="button" class="ml-2 mt-1 close" data-dismiss="toast" aria-label="Close"><span aria-hidden="true">&times;</span></button>
  </div>
  <div class="toast-body">See? Just like this.</div>
</div>

<div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
  <div class="toast-header">
    <img src="..." class="rounded mr-2" alt="...">
    <strong class="mr-auto">Bootstrap</strong>
    <small class="mt-2">2 seconds ago</small>
    <button type="button" class="ml-2 mt-1 close" data-dismiss="toast" aria-label="Close"><span aria-hidden="true">&times;</span></button>
  </div>
  <div class="toast-body">Heads up, toasts will stack automatically</div>
</div>

Placement

Place toasts with custom CSS as you need them. The top right is often used for notifications, as is the top middle. If you’re only ever going to show one toast at a time, put the positioning styles right on the .toast.

Bootstrap 11 mins ago
Hello, world! This is a toast message.
<div aria-live="polite" aria-atomic="true" style="position: relative; min-height: 200px;">
  <div class="toast" style="position: absolute; top: 0; right: 0;">
    <div class="toast-header">
      <img src="..." class="rounded mr-2" alt="...">
      <strong class="mr-auto">Bootstrap</strong>
      <small class="mt-2">11 mins ago</small>
      <button type="button" class="ml-2 mt-1 close" data-dismiss="toast" aria-label="Close"><span aria-hidden="true">&times;</span></button>
    </div>
    <div class="toast-body">Hello, world! This is a toast message.</div>
  </div>
</div>

For systems that generate more notifications, consider using a wrapping element so they can easily stack.

<div aria-live="polite" aria-atomic="true" style="position: relative; min-height: 200px;">
  <!-- Position it -->
  <div style="position: absolute; top: 0; right: 0;">

    <!-- Then put toasts within -->
    <div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
      <div class="toast-header">
        <img src="..." class="rounded mr-2" alt="...">
        <strong class="mr-auto">Bootstrap</strong>
        <small class="mt-2">just now</small>
        <button type="button" class="ml-2 mt-1 close" data-dismiss="toast" aria-label="Close"><span aria-hidden="true">&times;</span></button>
      </div>
      <div class="toast-body">See? Just like this.</div>
    </div>

    <div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
      <div class="toast-header">
        <img src="..." class="rounded mr-2" alt="...">
        <strong class="mr-auto">Bootstrap</strong>
        <small class="mt-2">2 seconds ago</small>
        <button type="button" class="ml-2 mt-1 close" data-dismiss="toast" aria-label="Close"><span aria-hidden="true">&times;</span></button>
      </div>
      <div class="toast-body">Heads up, toasts will stack automatically</div>
    </div>
  </div>
</div>

You can also get fancy with flexbox utilities to align toasts horizontally and/or vertically.

<!-- Flexbox container for aligning the toasts -->
<div aria-live="polite" aria-atomic="true" class="d-flex justify-content-center align-items-center" style="height: 200px;">

  <!-- Then put toasts within -->
  <div class="toast" role="alert" aria-live="assertive" aria-atomic="true">
    <div class="toast-header">
      <img src="..." class="rounded mr-2" alt="...">
      <strong class="mr-auto">Bootstrap</strong>
      <small class="mt-2">11 mins ago</small>
      <button type="button" class="ml-2 mt-1 close" data-dismiss="toast" aria-label="Close"><span aria-hidden="true">&times;</span></button>
    </div>
    <div class="toast-body">Hello, world! This is a toast message.</div>
  </div>
</div>

Accessibility

Toasts are intended to be small interruptions to your visitors or users, so to help those with screen readers and similar assistive technologies, you should wrap your toasts in an aria-live region. Changes to live regions (such as injecting/updating a toast component) are automatically announced by screen readers without needing to move the user’s focus or otherwise interrupt the user. Additionally, include aria-atomic="true" to ensure that the entire toast is always announced as a single (atomic) unit, rather than announcing what was changed (which could lead to problems if you only update part of the toast’s content, or if displaying the same toast content at a later point in time). If the information needed is important for the process, e.g. for a list of errors in a form, then use the alert component instead of toast.

Note that the live region needs to be present in the markup before the toast is generated or updated. If you dynamically generate both at the same time and inject them into the page, they will generally not be announced by assistive technologies.

You also need to adapt the role and aria-live level depending on the content. If it’s an important message like an error, use role="alert" aria-live="assertive", otherwise use role="status" aria-live="polite" attributes.

As the content you’re displaying changes, be sure to update the delay timeout to ensure people have enough time to read the toast.

<div class="toast" role="alert" aria-live="polite" aria-atomic="true" data-delay="10000">
  <div role="alert" aria-live="assertive" aria-atomic="true">...</div>
</div>

When using autohide: false, you must add a close button to allow users to dismiss the toast.

<div role="alert" aria-live="assertive" aria-atomic="true" class="toast" data-autohide="false">
  <div class="toast-header">
    <img src="..." class="rounded mr-2" alt="...">
    <strong class="mr-auto">Bootstrap</strong>
    <small class="mt-2">11 mins ago</small>
    <button type="button" class="ml-2 mt-1 close" data-dismiss="toast" aria-label="Close"><span aria-hidden="true">&times;</span></button>
  </div>
  <div class="toast-body">Hello, world! This is a toast message.</div>
</div>

JavaScript behavior

Usage

Initialize toasts via JavaScript:

<script>
  (function() {
    'use strict';

    $('.toast').toast(option);
  })();
</script>

Tooltips

Documentation and examples for adding custom Bootstrap tooltips with CSS and JavaScript using CSS3 for animations and data-attributes for local title storage.

Examples

Hover over the links below to see tooltips:

Placeholder text to demonstrate some inline links with tooltips. This is now just filler, no killer. Content placed here just to mimic the presence of real text. And all that just to give you an idea of how tooltips would look when used in real-world situations. So hopefully you've now seen how these tooltips on links can work in practice, once you use them on your own site or project.

<p>Placeholder text to demonstrate some <a href="#" data-toggle="tooltip" title="" data-original-title="Default tooltip">inline links</a> with tooltips. This is now just filler, no killer. Content placed here just to mimic the presence of <a href="#" data-toggle="tooltip" title="" data-original-title="Another tooltip">real text</a>. And all that just to give you an idea of how tooltips would look when used in real-world situations. So hopefully you've now seen how <a href="#" data-toggle="tooltip" title="" data-original-title="Another one here too">these tooltips on links</a> can work in practice, once you use them on <a href="#" data-toggle="tooltip" title="" data-original-title="The last tip!">your own</a> site or project.</p>

Hover over the buttons below to see the four tooltips directions: top, right, bottom, and left.

<button type="button" class="btn btn-primary" data-toggle="tooltip" data-placement="top" title="Tooltip on top">Tooltip on top</button>
<button type="button" class="btn btn-primary" data-toggle="tooltip" data-placement="right" title="Tooltip on right">Tooltip on right</button>
<button type="button" class="btn btn-primary" data-toggle="tooltip" data-placement="bottom" title="Tooltip on bottom">Tooltip on bottom</button>
<button type="button" class="btn btn-primary" data-toggle="tooltip" data-placement="left" title="Tooltip on left">Tooltip on left</button>

And with custom HTML added:

<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-html="true" title="<em>Tooltip</em> <u>with</u> <b>HTML</b>">Tooltip with HTML</button>

Disabled elements

Elements with the disabled attribute aren’t interactive, meaning users cannot focus, hover, or click them to trigger a tooltip (or popover). As a workaround, you’ll want to trigger the tooltip from a wrapper <div> or <span>, ideally made keyboard-focusable using tabindex="0", and override the pointer-events on the disabled element.

<span class="d-inline-block" tabindex="0" data-toggle="tooltip" title="Disabled tooltip">
  <button class="btn btn-primary" style="pointer-events: none;" type="button" disabled>Disabled button</button>
</span>

Utilities


Borders

Use border utilities to quickly style the border and border-radius of an element. Great for images, buttons, or any other element.

Border

Use border utilities to add or remove an element’s borders. Choose from all borders or one at a time.

Additive
<span class="border"></span>
<span class="border-top"></span>
<span class="border-right"></span>
<span class="border-bottom"></span>
<span class="border-left"></span>
Subtractive
<span class="border-0"></span>
<span class="border-top-0"></span>
<span class="border-right-0"></span>
<span class="border-bottom-0"></span>
<span class="border-left-0"></span>

Border color

Change the border color using utilities built on our theme colors.

<span class="border border-primary"></span>
<span class="border border-secondary"></span>
<span class="border border-success"></span>
<span class="border border-danger"></span>
<span class="border border-warning"></span>
<span class="border border-info"></span>
<span class="border border-light"></span>
<span class="border border-dark"></span>
<span class="border border-white"></span>

Border-radius

Add classes to an element to easily round its corners.

Example rounded image75x75 Example top rounded image75x75 Example right rounded image75x75 Example bottom rounded image75x75 Example left rounded image75x75 Completely round image75x75 Rounded pill image150x75 Example non-rounded image (overrides rounding applied elsewhere)75x75
<img src="..." alt="..." class="rounded">
<img src="..." alt="..." class="rounded-top">
<img src="..." alt="..." class="rounded-right">
<img src="..." alt="..." class="rounded-bottom">
<img src="..." alt="..." class="rounded-left">
<img src="..." alt="..." class="rounded-circle">
<img src="..." alt="..." class="rounded-pill">
<img src="..." alt="..." class="rounded-0">

Border-radius size

Use .rounded-lg or .rounded-sm for larger or smaller border-radius.

Example small rounded image75x75 Example large rounded image75x75

Clearfix

Quickly and easily clear floated content within a container by adding a clearfix utility.

Easily clear floats by adding .clearfix to the parent element. Can also be used as a mixin.

<div class="clearfix">...</div>

The following example shows how the clearfix can be used. Without the clearfix the wrapping div would not span around the buttons which would cause a broken layout.

<div class="bg-light clearfix">
  <button type="button" class="btn btn-primary float-left">Example Button floated left</button>
  <button type="button" class="btn btn-primary float-right">Example Button floated right</button>
</div>
More examples

Close icon

Use a generic close icon for dismissing content like modals and alerts.

Be sure to include text for screen readers, as we’ve done with aria-label.

<button type="button" class="close" aria-label="Close">
  <span aria-hidden="true">&times;</span>
</button>
More examples

Colors

Convey meaning through color with a handful of color utility classes. Includes support for styling links with hover states, too.

Color

.text-primary

.text-secondary

.text-success

.text-danger

.text-warning

.text-info

.text-light

.text-dark

.text-body

.text-muted

.text-white

.text-black-50

.text-white-50

<p class="text-primary">.text-primary</p>
<p class="text-secondary">.text-secondary</p>
<p class="text-success">.text-success</p>
<p class="text-danger">.text-danger</p>
<p class="text-warning">.text-warning</p>
<p class="text-info">.text-info</p>
<p class="text-light bg-dark">.text-light</p>
<p class="text-dark">.text-dark</p>
<p class="text-body">.text-body</p>
<p class="text-muted">.text-muted</p>
<p class="text-white bg-dark">.text-white</p>
<p class="text-black-50">.text-black-50</p>
<p class="text-white-50 bg-dark">.text-white-50</p>

Contextual text classes also work well on anchors with the provided hover and focus states. Note that the .text-white and .text-muted class has no additional link styling beyond underline.

<p><a href="#" class="text-primary">Primary link</a></p>
<p><a href="#" class="text-secondary">Secondary link</a></p>
<p><a href="#" class="text-success">Success link</a></p>
<p><a href="#" class="text-danger">Danger link</a></p>
<p><a href="#" class="text-warning">Warning link</a></p>
<p><a href="#" class="text-info">Info link</a></p>
<p><a href="#" class="text-light bg-dark">Light link</a></p>
<p><a href="#" class="text-dark">Dark link</a></p>
<p><a href="#" class="text-muted">Muted link</a></p>
<p><a href="#" class="text-white bg-dark">White link</a></p>

Background color

Similar to the contextual text color classes, easily set the background of an element to any contextual class. Anchor components will darken on hover, just like the text classes. Background utilities do not set color, so in some cases you’ll want to use .text-* utilities.

.bg-primary
.bg-secondary
.bg-success
.bg-danger
.bg-warning
.bg-info
.bg-light
.bg-dark
.bg-white
.bg-transparent
<div class="p-3 mb-2 bg-primary text-white">.bg-primary</div>
<div class="p-3 mb-2 bg-secondary text-white">.bg-secondary</div>
<div class="p-3 mb-2 bg-success text-white">.bg-success</div>
<div class="p-3 mb-2 bg-danger text-white">.bg-danger</div>
<div class="p-3 mb-2 bg-warning text-dark">.bg-warning</div>
<div class="p-3 mb-2 bg-info text-white">.bg-info</div>
<div class="p-3 mb-2 bg-light text-dark">.bg-light</div>
<div class="p-3 mb-2 bg-dark text-white">.bg-dark</div>
<div class="p-3 mb-2 bg-white text-dark">.bg-white</div>
<div class="p-3 mb-2 bg-transparent text-dark">.bg-transparent</div>

Display

Quickly and responsively toggle the display value of components and more with our display utilities. Includes support for some of the more common values, as well as some extras for controlling display when printing.

How it works

Change the value of the display property with our responsive display utility classes. We purposely support only a subset of all possible values for display. Classes can be combined for various effects as you need.

Notation

Display utility classes that apply to all breakpoints, from xs to xl, have no breakpoint abbreviation in them. This is because those classes are applied from min-width: 0; and up, and thus are not bound by a media query. The remaining breakpoints, however, do include a breakpoint abbreviation.

As such, the classes are named using the format:

  • .d-{value} for xs
  • .d-{breakpoint}-{value} for sm, md, lg, and xl.

Where value is one of:

  • none
  • inline
  • inline-block
  • block
  • table
  • table-cell
  • table-row
  • flex
  • inline-flex

The display values can be altered by changing the $displays variable and recompiling the SCSS.

The media queries affect screen widths with the given breakpoint or larger. For example, .d-lg-none sets display: none; on both lg and xl screens.

Examples

d-inline
d-inline
<div class="d-inline p-2 bg-primary text-white">d-inline</div>
<div class="d-inline p-2 bg-primary text-white">d-inline</div>
d-block d-block
<span class="d-block p-2 bg-primary text-white">d-block</span>
<span class="d-block p-2 bg-primary text-white">d-block</span>

Hiding elements

For faster mobile-friendly development, use responsive display classes for showing and hiding elements by device. Avoid creating entirely different versions of the same site, instead hide elements responsively for each screen size.

To hide elements simply use the .d-none class or one of the .d-{sm,md,lg,xl}-none classes for any responsive screen variation.

To show an element only on a given interval of screen sizes you can combine one .d-*-none class with a .d-*-* class, for example .d-none .d-md-block .d-xl-none will hide the element for all screen sizes except on medium and large devices.

Screen Size Class
Hidden on all .d-none
Hidden only on xs .d-none .d-sm-block
Hidden only on sm .d-sm-none .d-md-block
Hidden only on md .d-md-none .d-lg-block
Hidden only on lg .d-lg-none .d-xl-block
Hidden only on xl .d-xl-none
Visible on all .d-block
Visible only on xs .d-block .d-sm-none
Visible only on sm .d-none .d-sm-block .d-md-none
Visible only on md .d-none .d-md-block .d-lg-none
Visible only on lg .d-none .d-lg-block .d-xl-none
Visible only on xl .d-none .d-xl-block
hide on lg and wider screens
hide on screens smaller than lg
<div class="d-lg-none">hide on lg and wider screens</div>
<div class="d-none d-lg-block">hide on screens smaller than lg</div>

Display in print

Change the display value of elements when printing with our print display utility classes. Includes support for the same display values as our responsive .d-* utilities.

  • .d-print-none
  • .d-print-inline
  • .d-print-inline-block
  • .d-print-block
  • .d-print-table
  • .d-print-table-row
  • .d-print-table-cell
  • .d-print-flex
  • .d-print-inline-flex

The print and display classes can be combined.

Screen Only (Hide on print only)
Print Only (Hide on screen only)
Hide up to large on screen, but always show on print
<div class="d-print-none">Screen Only (Hide on print only)</div>
<div class="d-none d-print-block">Print Only (Hide on screen only)</div>
<div class="d-none d-lg-block d-print-block">Hide up to large on screen, but always show on print</div>

Embed

Create responsive video or slideshow embeds based on the width of the parent by creating an intrinsic ratio that scales on any device.

About

Rules are directly applied to <iframe>, <embed>, <video>, and <object> elements; optionally use an explicit descendant class .embed-responsive-item when you want to match the styling for other attributes.

Pro-Tip! You don’t need to include frameborder="0" in your <iframe>s as we override that for you.

Example

Wrap any embed like an <iframe> in a parent element with .embed-responsive and an aspect ratio. The .embed-responsive-item isn’t strictly required, but we encourage it.

<div class="embed-responsive embed-responsive-16by9">
  <iframe class="embed-responsive-item" src="https://www.youtube.com/embed/lSNmfy_KOJg" allowfullscreen></iframe>
</div>

Aspect ratios

Aspect ratios can be customized with modifier classes. By default the following ratio classes are provided:

<!-- 21:9 aspect ratio -->
<div class="embed-responsive embed-responsive-21by9">
  <iframe class="embed-responsive-item" src="..."></iframe>
</div>

<!-- 16:9 aspect ratio -->
<div class="embed-responsive embed-responsive-16by9">
  <iframe class="embed-responsive-item" src="..."></iframe>
</div>

<!-- 4:3 aspect ratio -->
<div class="embed-responsive embed-responsive-4by3">
  <iframe class="embed-responsive-item" src="..."></iframe>
</div>

<!-- 1:1 aspect ratio -->
<div class="embed-responsive embed-responsive-1by1">
  <iframe class="embed-responsive-item" src="..."></iframe>
</div>

Flex

Quickly manage the layout, alignment, and sizing of grid columns, navigation, components, and more with a full suite of responsive flexbox utilities. For more complex implementations, custom CSS may be necessary.

Enable flex behaviors

Apply display utilities to create a flexbox container and transform direct children elements into flex items. Flex containers and items are able to be modified further with additional flex properties.

I'm a flexbox container!
<div class="d-flex p-2 bd-highlight">I'm a flexbox container!</div>
I'm an inline flexbox container!
<div class="d-inline-flex p-2 bd-highlight">I'm an inline flexbox container!</div>

Responsive variations also exist for .d-flex and .d-inline-flex.

  • .d-flex
  • .d-inline-flex
  • .d-sm-flex
  • .d-sm-inline-flex
  • .d-md-flex
  • .d-md-inline-flex
  • .d-lg-flex
  • .d-lg-inline-flex
  • .d-xl-flex
  • .d-xl-inline-flex

Direction

Set the direction of flex items in a flex container with direction utilities. In most cases you can omit the horizontal class here as the browser default is row. However, you may encounter situations where you needed to explicitly set this value (like responsive layouts).

Use .flex-row to set a horizontal direction (the browser default), or .flex-row-reverse to start the horizontal direction from the opposite side.

Flex item 1
Flex item 2
Flex item 3
Flex item 1
Flex item 2
Flex item 3
<div class="d-flex flex-row bd-highlight mb-3">
  <div class="p-2 bd-highlight">Flex item 1</div>
  <div class="p-2 bd-highlight">Flex item 2</div>
  <div class="p-2 bd-highlight">Flex item 3</div>
</div>
<div class="d-flex flex-row-reverse bd-highlight">
  <div class="p-2 bd-highlight">Flex item 1</div>
  <div class="p-2 bd-highlight">Flex item 2</div>
  <div class="p-2 bd-highlight">Flex item 3</div>
</div>

Use .flex-column to set a vertical direction, or .flex-column-reverse to start the vertical direction from the opposite side.

Flex item 1
Flex item 2
Flex item 3
Flex item 1
Flex item 2
Flex item 3
<div class="d-flex flex-column bd-highlight mb-3">
  <div class="p-2 bd-highlight">Flex item 1</div>
  <div class="p-2 bd-highlight">Flex item 2</div>
  <div class="p-2 bd-highlight">Flex item 3</div>
</div>
<div class="d-flex flex-column-reverse bd-highlight">
  <div class="p-2 bd-highlight">Flex item 1</div>
  <div class="p-2 bd-highlight">Flex item 2</div>
  <div class="p-2 bd-highlight">Flex item 3</div>
</div>

Use .flex-grow-* utilities to toggle a flex item’s ability to grow to fill available space. In the example below, the .flex-grow-1 elements uses all available space it can, while allowing the remaining two flex items their necessary space.

Flex item
Flex item
Third flex item
<div class="d-flex bd-highlight">
  <div class="p-2 flex-grow-1 bd-highlight">Flex item</div>
  <div class="p-2 bd-highlight">Flex item</div>
  <div class="p-2 bd-highlight">Third flex item</div>
</div>

Use .flex-shrink-* utilities to toggle a flex item’s ability to shrink if necessary. In the example below, the second flex item with .flex-shrink-1 is forced to wrap its contents to a new line, “shrinking” to allow more space for the previous flex item with .w-100.

Flex item
Flex item
<div class="d-flex bd-highlight">
  <div class="p-2 w-100 bd-highlight">Flex item</div>
  <div class="p-2 flex-shrink-1 bd-highlight">Flex item</div>
</div>

Responsive variations also exist for flex-grow and flex-shrink.

  • .flex-{grow|shrink}-0
  • .flex-{grow|shrink}-1
  • .flex-sm-{grow|shrink}-0
  • .flex-sm-{grow|shrink}-1
  • .flex-md-{grow|shrink}-0
  • .flex-md-{grow|shrink}-1
  • .flex-lg-{grow|shrink}-0
  • .flex-lg-{grow|shrink}-1
  • .flex-xl-{grow|shrink}-0
  • .flex-xl-{grow|shrink}-1

Auto margins

Flexbox can do some pretty awesome things when you mix flex alignments with auto margins. Shown below are three examples of controlling flex items via auto margins: default (no auto margin), pushing two items to the right (.mr-auto), and pushing two items to the left (.ml-auto).

Unfortunately, IE10 and IE11 do not properly support auto margins on flex items whose parent has a non-default justify-content value. See this StackOverflow answer for more details.

<div class="d-flex align-items-start flex-column bd-highlight mb-3" style="height: 200px;">
  <div class="mb-auto p-2 bd-highlight">Flex item</div>
  <div class="p-2 bd-highlight">Flex item</div>
  <div class="p-2 bd-highlight">Flex item</div>
</div>

<div class="d-flex align-items-end flex-column bd-highlight mb-3" style="height: 200px;">
  <div class="p-2 bd-highlight">Flex item</div>
  <div class="p-2 bd-highlight">Flex item</div>
  <div class="mt-auto p-2 bd-highlight">Flex item</div>
</div>

Wrap

Change how flex items wrap in a flex container. Choose from no wrapping at all (the browser default) with .flex-nowrap, wrapping with .flex-wrap, or reverse wrapping with .flex-wrap-reverse.

Order

Change the visual order of specific flex items with a handful of order utilities. We only provide options for making an item first or last, as well as a reset to use the DOM order. As order takes any integer value (e.g., 5), add custom CSS for any additional values needed.

First flex item
Second flex item
Third flex item
<div class="d-flex flex-nowrap bd-highlight">
  <div class="order-3 p-2 bd-highlight">First flex item</div>
  <div class="order-2 p-2 bd-highlight">Second flex item</div>
  <div class="order-1 p-2 bd-highlight">Third flex item</div>

Align content

Use align-content utilities on flexbox containers to align flex items together on the cross axis. Choose from start (browser default), end, center, between, around, or stretch. To demonstrate these utilities, we’ve enforced flex-wrap: wrap and increased the number of flex items.

Heads up! This property has no effect on single rows of flex items.

Float

Toggle floats on any element, across any breakpoint, using our responsive float utilities.

Classes

Toggle a float with a class:

Float left on all viewport sizes

Float right on all viewport sizes

Don't float on all viewport sizes
<div class="float-left">Float left on all viewport sizes</div><br>
<div class="float-right">Float right on all viewport sizes</div><br>
<div class="float-none">Don't float on all viewport sizes</div>

Mixins

Or by Sass mixin:

.element {
  @include float-left;
}

.another-element {
  @include float-right;
}

.one-more {
  @include float-none;
}

Responsive

Responsive variations also exist for each float value.

Float left on viewports sized SM (small) or wider

Float left on viewports sized MD (medium) or wider

Float left on viewports sized LG (large) or wider

Float left on viewports sized XL (extra-large) or wider

Image replacement

Swap text for background images with the image replacement class.

Utilize the .text-hide class or mixin to help replace an element’s text content with a background image.

<h1 class="text-hide">Custom heading</h1>
// Usage as a mixin
.heading {
  @include text-hide;
}

Use the .text-hide class to maintain the accessibility and SEO benefits of heading tags, but want to utilize a background-image instead of text.

Logo

<h1 class="text-hide" style="background-image: url('...');">Logo</h1>

Interactions

Utility classes that change how users interact with the contents of a website.

Text selection

Change how the content is selected when the user interacts with it. Note that Internet Explorer and Legacy Edge have no support for the all value for user-select, and as such, .user-select-all is not supported by either browser.

This paragraph will be entirely selected when clicked by the user.

This paragraph has the default select behavior.

This paragraph will not be selectable when clicked by the user.

<p class="user-select-all">This paragraph will be entirely selected when clicked by the user.</p>
<p class="user-select-auto">This paragraph has the default select behavior.</p>
<p class="user-select-none">This paragraph will not be selectable when clicked by the user.</p>

Overflow

Use these shorthand utilities for quickly configuring how content overflows an element.

Barebones overflow functionality is provided for two values by default, and they are not responsive.

This is an example of using .overflow-auto on an element with set width and height dimensions. By design, this content will vertically scroll.

This is an example of using .overflow-hidden on an element with set width and height dimensions.

<div class="overflow-auto">...</div>
<div class="overflow-hidden">...</div>
More examples

Position

Use these shorthand utilities for quickly configuring the position of an element.

Common values

Quick positioning classes are available, though they are not responsive.

<div class="position-static">...</div>
<div class="position-relative">...</div>
<div class="position-absolute">...</div>
<div class="position-fixed">...</div>
<div class="position-sticky">...</div>

Fixed top

Position an element at the top of the viewport, from edge to edge. Be sure you understand the ramifications of fixed position in your project; you may need to add additional CSS.

<div class="fixed-top">...</div>

Fixed bottom

Position an element at the bottom of the viewport, from edge to edge. Be sure you understand the ramifications of fixed position in your project; you may need to add additional CSS.

<div class="fixed-bottom">...</div>

Sticky top

Position an element at the top of the viewport, from edge to edge, but only after you scroll past it. The .sticky-top utility uses CSS’s position: sticky, which isn’t fully supported in all browsers.

IE11 and IE10 will render position: sticky as position: relative. As such, we wrap the styles in a @supports query, limiting the stickiness to only browsers that can render it properly.

<div class="sticky-top">...</div>
More examples

Screen readers

Use screen reader utilities to hide elements on all devices except screen readers.

Hide an element to all devices except screen readers with .sr-only. Combine .sr-only with .sr-only-focusable to show the element again when it’s focused (e.g. by a keyboard-only user). Can also be used as mixins.

<a class="sr-only sr-only-focusable" href="#content">Skip to main content</a>
// Usage as a mixin
.skip-navigation {
  @include sr-only;
  @include sr-only-focusable;
}
More examples

Shadows

Add or remove shadows to elements with box-shadow utilities.

Examples

While shadows on components are disabled by default in Bootstrap and can be enabled via $enable-shadows, you can also quickly add or remove a shadow with our box-shadow utility classes. Includes support for .shadow-none and three default sizes (which have associated variables to match).

No shadow
Small shadow
Regular shadow
Larger shadow
<div class="shadow-none p-3 mb-5 bg-light rounded">No shadow</div>
<div class="shadow-sm p-3 mb-4 bg-white rounded">Small shadow</div>
<div class="shadow p-3 mb-4 bg-white rounded">Regular shadow</div>
<div class="shadow-lg p-3 bg-white rounded">Larger shadow</div>
More examples

Sizing

Easily make an element as wide or as tall with our width and height utilities.

Relative to the parent

Includes support for 25%, 50%, 75%, 100%, and auto by default. Modify those values as you need to generate different utilities here.

Width 25%
Width 50%
Width 75%
Width 100%
Width auto
<div class="w-25 p-3 bd-highlight">Width 25%</div>
<div class="w-50 p-3 bd-highlight">Width 50%</div>
<div class="w-75 p-3 bd-highlight">Width 75%</div>
<div class="w-100 p-3 bd-highlight">Width 100%</div>
<div class="w-auto p-3 bd-highlight">Width auto</div>
Height 25%
Height 50%
Height 75%
Height 100%
Height auto
<div class="bd-highlight" style="height: 100px;">
    <div class="h-25 d-inline-block bd-highlight" style="width: 120px">Height 25%</div>
    <div class="h-50 d-inline-block bd-highlight" style="width: 120px">Height 50%</div>
    <div class="h-75 d-inline-block bd-highlight" style="width: 120px">Height 75%</div>
    <div class="h-100 d-inline-block bd-highlight" style="width: 120px">Height 100%</div>
    <div class="h-auto d-inline-block bd-highlight" style="width: 120px">Height auto</div>
</div>

You can also use min-width: 100%; max-width: 100%; and max-height: 100%; utilities as needed.

PlaceholderMax-width 100%
<img src="..." class="mw-100" alt="...">
Max-height 100%
<div class="bd-highlight" style="height: 100px;">
    <div class="mh-100 bd-highlight" style="width: 100px; height: 200px;">Max-height 100%</div>
</div>

Relative to the viewport

You can also use utilities to set the width and height relative to the viewport.

<div class="min-vw-100">Min-width 100vw</div>
<div class="min-vh-100">Min-height 100vh</div>
<div class="vw-100">Width 100vw</div>
<div class="vh-100">Height 100vh</div>

Spacing

Bootstrap includes a wide range of shorthand responsive margin and padding utility classes to modify an element’s appearance.

How it works

Assign responsive-friendly margin or padding values to an element or a subset of its sides with shorthand classes. Includes support for individual properties, all properties, and vertical and horizontal properties. Classes are built from a default Sass map ranging from .25rem to 3rem.

Notation

Spacing utilities that apply to all breakpoints, from xs to xl, have no breakpoint abbreviation in them. This is because those classes are applied from min-width: 0 and up, and thus are not bound by a media query. The remaining breakpoints, however, do include a breakpoint abbreviation.

The classes are named using the format {property}{sides}-{size} for xs and {property}{sides}-{breakpoint}-{size} for sm, md, lg, and xl.

Where property is one of:

  • m - for classes that set margin
  • p - for classes that set padding

Where sides is one of:

  • t - for classes that set margin-top or padding-top
  • b - for classes that set margin-bottom or padding-bottom
  • l - for classes that set margin-left or padding-left
  • r - for classes that set margin-right or padding-right
  • x - for classes that set both *-left and *-right
  • y - for classes that set both *-top and *-bottom
  • blank - for classes that set a margin or padding on all 4 sides of the element

Where size is one of:

  • 0 - for classes that eliminate the margin or padding by setting it to 0
  • 1 - (by default) for classes that set the margin or padding to $spacer * .25
  • 2 - (by default) for classes that set the margin or padding to $spacer * .5
  • 3 - (by default) for classes that set the margin or padding to $spacer
  • 4 - (by default) for classes that set the margin or padding to $spacer * 1.5
  • 5 - (by default) for classes that set the margin or padding to $spacer * 3
  • auto - for classes that set the margin to auto

(You can add more sizes by adding entries to the $spacers Sass map variable.)

Horizontal centering

Additionally, Bootstrap also includes an .mx-auto class for horizontally centering fixed-width block level content—that is, content that has display: block and a width set—by setting the horizontal margins to auto.

Centered element
<div class="mx-auto" style="width: 200px;">Centered element</div>

Negative margin

In CSS, margin properties can utilize negative values (padding cannot). As of 4.2, we’ve added negative margin utilities for every non-zero integer size listed above (e.g., 1, 2, 3, 4, 5). These utilities are ideal for customizing grid column gutters across breakpoints.

The syntax is nearly the same as the default, positive margin utilities, but with the addition of n before the requested size. Here’s an example class that’s the opposite of .mt-1:

.mt-n1 {
  margin-top: -0.25rem !important;
}

Here’s an example of customizing the Bootstrap grid at the medium (md) breakpoint and above. We’ve increased the .col padding with .px-md-5 and then counteracted that with .mx-md-n5 on the parent .row.

Custom column padding
Custom column padding
<div class="row mx-md-n5">
  <div class="col px-md-5"><div class="p-3 border bg-light">Custom column padding</div></div>
  <div class="col px-md-5"><div class="p-3 border bg-light">Custom column padding</div></div>
</div>

Text

Documentation and examples for common text utilities to control alignment, wrapping, weight, and more.

Text alignment

Easily realign text to components with text alignment classes.

Some placeholder text to demonstrate justified text alignment. Will you do the same for me? It's time to face the music I'm no longer your muse. Heard it's beautiful, be the judge and my girls gonna take a vote. I can feel a phoenix inside of me. Heaven is jealous of our love, angels are crying from up above. Yeah, you take me to utopia.

<p class="text-justify">Some placeholder text to demonstrate justified text alignment. Will you do the same for me? It's time to face the music I'm no longer your muse. Heard it's beautiful, be the judge and my girls gonna take a vote. I can feel a phoenix inside of me. Heaven is jealous of our love, angels are crying from up above. Yeah, you take me to utopia.</p>

For left, right, and center alignment, responsive classes are available that use the same viewport width breakpoints as the grid system.

Left aligned text on all viewport sizes.

Center aligned text on all viewport sizes.

Right aligned text on all viewport sizes.

Left aligned text on viewports sized SM (small) or wider.

Left aligned text on viewports sized MD (medium) or wider.

Left aligned text on viewports sized LG (large) or wider.

Left aligned text on viewports sized XL (extra-large) or wider.

<p class="text-left">Left aligned text on all viewport sizes.</p>
<p class="text-center">Center aligned text on all viewport sizes.</p>
<p class="text-right">Right aligned text on all viewport sizes.</p>

<p class="text-sm-left">Left aligned text on viewports sized SM (small) or wider.</p>
<p class="text-md-left">Left aligned text on viewports sized MD (medium) or wider.</p>
<p class="text-lg-left">Left aligned text on viewports sized LG (large) or wider.</p>
<p class="text-xl-left">Left aligned text on viewports sized XL (extra-large) or wider.</p></p>

Text wrapping and overflow

Wrap text with a .text-wrap class.

This text should wrap.
<div class="badge badge-primary text-wrap" style="width: 6rem;">This text should wrap.</div>

Prevent text from wrapping with a .text-nowrap class.

This text should overflow the parent.
<div class="text-nowrap bd-highlight" style="width: 8rem;">This text should overflow the parent.</div>

For longer content, you can add a .text-truncate class to truncate the text with an ellipsis. Requires display: inline-block or display: block.

Praeterea iter est quasdam res quas ex communi.
Praeterea iter est quasdam res quas ex communi.
<!-- Block level -->
<div class="row">
  <div class="col-2 text-truncate">Praeterea iter est quasdam res quas ex communi.</div>
</div>

<!-- Inline level -->
<span class="d-inline-block text-truncate" style="max-width: 150px;">Praeterea iter est quasdam res quas ex communi.</span>

Word break

Prevent long strings of text from breaking your components' layout by using .text-break to set word-wrap: break-word and word-break: break-word. We use word-wrap instead of the more common overflow-wrap for wider browser support, and add the deprecated word-break: break-word to avoid issues with flex containers.

mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm

<p class="text-break">mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm</p>

Text transform

Transform text in components with text capitalization classes.

Lowercased text.

Uppercased text.

CapiTaliZed text.

<p class="text-lowercase">Lowercased text.</p>
<p class="text-uppercase">Uppercased text.</p>
<p class="text-capitalize">CapiTaliZed text.</p>

Note how .text-capitalize only changes the first letter of each word, leaving the case of any other letters unaffected.

Font weight and italics

Quickly change the weight (boldness) of text or italicize text.

Bold text.

Bolder weight text (relative to the parent element).

Normal weight text.

Light weight text.

Lighter weight text (relative to the parent element).

Italic text.

<p class="font-weight-bold">Bold text.</p>
<p class="font-weight-bolder">Bolder weight text (relative to the parent element).</p>
<p class="font-weight-normal">Normal weight text.</p>
<p class="font-weight-light">Light weight text.</p>
<p class="font-weight-lighter">Lighter weight text (relative to the parent element).</p>
<p class="font-italic">Italic text.</p>

Monospace

Change a selection to our monospace font stack with .text-monospace.

This is in monospace

<p class="text-monospace">This is in monospace</p>

Reset color

Reset a text or link’s color with .text-reset, so that it inherits the color from its parent.

Muted text with a reset link.

<p class="text-muted">Muted text with a <a href="#" class="text-reset">reset link</a>.</p>

Text decoration

Remove a text decoration with a .text-decoration-none class.

<a href="#" class="text-decoration-none">Non-underlined link</a>

Vertical alignment

Easily change the vertical alignment of inline, inline-block, inline-table, and table cell elements.

Change the alignment of elements with the vertical-alignment utilities. Please note that vertical-align only affects inline, inline-block, inline-table, and table cell elements.

Choose from .align-baseline, .align-top, .align-middle, .align-bottom, .align-text-bottom, and .align-text-top as needed.

With inline elements:

baseline top middle bottom text-top text-bottom
<span class="align-baseline">baseline</span>
<span class="align-top">top</span>
<span class="align-middle">middle</span>
<span class="align-bottom">bottom</span>
<span class="align-text-top">text-top</span>
<span class="align-text-bottom">text-bottom</span>

With table cells:

baseline top middle bottom text-top text-bottom
<table style="height: 100px;">
  <tbody>
    <tr>
      <td class="align-baseline">baseline</td>
      <td class="align-top">top</td>
      <td class="align-middle">middle</td>
      <td class="align-bottom">bottom</td>
      <td class="align-text-top">text-top</td>
      <td class="align-text-bottom">text-bottom</td>
    </tr>
  </tbody>
</table>

Visibility

Control the visibility, without modifying the display, of elements with visibility utilities.

Set the visibility of elements with our visibility utilities. These utility classes do not modify the display value at all and do not affect layout – .invisible elements still take up space in the page. Content will be hidden both visually and for assistive technology/screen reader users.

Apply .visible or .invisible as needed.

<div class="visible">...</div>
<div class="invisible">...</div>
