Example

Toggleable, contextual menu for displaying lists of links. Made interactive with the dropdown JavaScript plugin.

<ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu">
  <li><a tabindex="-1" href="#">Action</a></li>
  <li><a tabindex="-1" href="#">Another action</a></li>
  <li><a tabindex="-1" href="#">Something else here</a></li>
  <li class="divider"></li>
  <li><a tabindex="-1" href="#">Separated link</a></li>
</ul>

Markup

Looking at just the dropdown menu, here's the required HTML. You need to wrap the dropdown's trigger and the dropdown menu within .dropdown, or another element that declares position: relative;. Then just create the menu.

<div class="dropdown">
  <!-- Link or button to toggle dropdown -->
  <ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
    <li><a tabindex="-1" href="#">Action</a></li>
    <li><a tabindex="-1" href="#">Another action</a></li>
    <li><a tabindex="-1" href="#">Something else here</a></li>
    <li class="divider"></li>
    <li><a tabindex="-1" href="#">Separated link</a></li>
  </ul>
</div>

Options

Align menus to the right and add include additional levels of dropdowns.

Aligning the menus

Add .pull-right to a .dropdown-menu to right align the dropdown menu.

<ul class="dropdown-menu pull-right" role="menu" aria-labelledby="dLabel">
  ...
</ul>

Sub menus on dropdowns

Add an extra level of dropdown menus, appearing on hover like those of OS X, with some simple markup additions. Add .dropdown-submenu to any li in an existing dropdown menu for automatic styling.

Default

Dropup

Left submenu

<ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
  ...
  <li class="dropdown-submenu">
    <a tabindex="-1" href="#">More options</a>
    <ul class="dropdown-menu">
      ...
    </ul>
  </li>
</ul>

Examples

Two basic options, along with two more specific variations.

Single button group

Wrap a series of buttons with .btn in .btn-group.

<div class="btn-group">
  <button class="btn">1</button>
  <button class="btn">2</button>
  <button class="btn">3</button>
</div>

Multiple button groups

Combine sets of <div class="btn-group"> into a <div class="btn-toolbar"> for more complex components.

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

Vertical button groups

Make a set of buttons appear vertically stacked rather than horizontally.

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

Checkbox and radio flavors

Button groups can also function as radios, where only one button may be active, or checkboxes, where any number of buttons may be active. View the JavaScript docs for that.

Dropdowns in button groups

Heads up! Buttons with dropdowns must be individually wrapped in their own .btn-group within a .btn-toolbar for proper rendering.

Overview and examples

Use any button to trigger a dropdown menu by placing it within a .btn-group and providing the proper menu markup.

<div class="btn-group">
  <a class="btn dropdown-toggle" data-toggle="dropdown" href="#">
    Action
    <span class="caret"></span>
  </a>
  <ul class="dropdown-menu">
    <!-- dropdown menu links -->
  </ul>
</div>

Works with all button sizes

Button dropdowns work at any size: .btn-large, .btn-small, or .btn-mini.

Requires JavaScript

Button dropdowns require the Bootstrap dropdown plugin to function.

In some cases—like mobile—dropdown menus will extend outside the viewport. You need to resolve the alignment manually or with custom JavaScript.

Split button dropdowns

Building on the button group styles and markup, we can easily create a split button. Split buttons feature a standard action on the left and a dropdown toggle on the right with contextual links.

<div class="btn-group">
  <button class="btn">Action</button>
  <button class="btn dropdown-toggle" data-toggle="dropdown">
    <span class="caret"></span>
  </button>
  <ul class="dropdown-menu">
    <!-- dropdown menu links -->
  </ul>
</div>

Sizes

Utilize the extra button classes .btn-mini, .btn-small, or .btn-large for sizing.

<div class="btn-group">
  <button class="btn btn-mini">Action</button>
  <button class="btn btn-mini dropdown-toggle" data-toggle="dropdown">
    <span class="caret"></span>
  </button>
  <ul class="dropdown-menu">
    <!-- dropdown menu links -->
  </ul>
</div>

Dropup menus

Dropdown menus can also be toggled from the bottom up by adding a single class to the immediate parent of .dropdown-menu. It will flip the direction of the .caret and reposition the menu itself to move from the bottom up instead of top down.

<div class="btn-group dropup">
  <button class="btn">Dropup</button>
  <button class="btn dropdown-toggle" data-toggle="dropdown">
    <span class="caret"></span>
  </button>
  <ul class="dropdown-menu">
    <!-- dropdown menu links -->
  </ul>
</div>

Navs available in Bootstrap have shared markup, starting with the base .nav class, as well as shared states. Swap modifier classes to switch between each style.

Tabs

Note the .nav-tabs class requires the .nav base class.

<ul class="nav nav-tabs">
  <li class="active">
    <a href="#">Home</a>
  </li>
  <li><a href="#">...</a></li>
  <li><a href="#">...</a></li>
</ul>

List

Swap the tabs class for .nav-list.

<ul class="nav nav-list">
  <li class="active">
    <a href="#">Home</a>
  </li>
  <li><a href="#">...</a></li>
  <li><a href="#">...</a></li>
</ul>

Pills

Take that same HTML, but use .nav-pills instead:

<ul class="nav nav-pills">
  <li class="active">
    <a href="#">Home</a>
  </li>
  <li><a href="#">...</a></li>
  <li><a href="#">...</a></li>
</ul>

Pills are also vertically stackable. Just add .nav-stacked.

<ul class="nav nav-pills nav-stacked">
  ...
</ul>

Options

Justified links

Easily make tabs or pills equal widths of their parent with .nav-justified.

<ul class="nav nav-tabs nav-justified">
  ...
</ul>

<ul class="nav nav-pills nav-justified">
  ...
</ul>

Disabled state

For any nav component (tabs, pills, or list), add .disabled for gray links and no hover effects. Links will remain clickable, however, unless you remove the href attribute. Alternatively, you could implement custom JavaScript to prevent those clicks.

<ul class="nav nav-pills">
  ...
  <li class="disabled"><a href="#">Home</a></li>
  ...
</ul>

Component alignment

To align nav links, use the .pull-left or .pull-right utility classes. Both classes will add a CSS float in the specified direction.

Dropdowns

Add dropdown menus with a little extra HTML and the dropdowns JavaScript plugin.

Tabs with dropdowns

<ul class="nav nav-tabs">
  <li class="dropdown">
    <a class="dropdown-toggle"
       data-toggle="dropdown"
       href="#">
        Dropdown
        <b class="caret"></b>
      </a>
    <ul class="dropdown-menu">
      <!-- links -->
    </ul>
  </li>
</ul>

Pills with dropdowns

<ul class="nav nav-pills">
  <li class="dropdown">
    <a class="dropdown-toggle"
       data-toggle="dropdown"
       href="#">
        Dropdown
        <b class="caret"></b>
      </a>
    <ul class="dropdown-menu">
      <!-- links -->
    </ul>
  </li>
</ul>

Basic navbar

To start, navbars are static (not fixed to the top) and include support for a project name and basic navigation. Place one anywhere within a .container, which sets the width of your site and content.

<div class="navbar">
  <a class="brand" href="#">Title</a>
  <ul class="nav">
    <li class="active"><a href="#">Home</a></li>
    <li><a href="#">Link</a></li>
    <li><a href="#">Link</a></li>
  </ul>
</div>

Navbar components

Brand

A simple link to show your brand or project name only requires an anchor tag.

<a class="brand" href="#">Project name</a>

Nav links

Nav items are simple to add via unordered lists.

<ul class="nav">
  <li class="active">
    <a href="#">Home</a>
  </li>
  <li><a href="#">Link</a></li>
  <li><a href="#">Link</a></li>
</ul>

You can easily add dividers to your nav links with an empty list item and a simple class. Just add this between links:

<ul class="nav">
  ...
  <li class="divider-vertical"></li>
  ...
</ul>

Forms

To properly style and position a form within the navbar, add the appropriate classes as shown below. For a default form, include .navbar-form and either .pull-left or .pull-right to properly align it.

<form class="navbar-form pull-left">
  <input type="text" class="span2">
  <button type="submit" class="btn">Submit</button>
</form>

Search form

For a more customized search form, add .navbar-search to the form and .search-query to the input for specialized styles in the navbar.

<form class="navbar-search pull-left">
  <input type="text" class="search-query" placeholder="Search">
</form>

Component alignment

Align nav links, search form, or text, use the .pull-left or .pull-right utility classes. Both classes will add a CSS float in the specified direction.

Using dropdowns

Add dropdowns and dropups to the nav with a bit of markup and the dropdowns JavaScript plugin.

<ul class="nav">
  <li class="dropdown">
    <a href="#" class="dropdown-toggle" data-toggle="dropdown">
      Account
      <b class="caret"></b>
    </a>
    <ul class="dropdown-menu">
      ...
    </ul>
  </li>
</ul>

Visit the JavaScript dropdowns documentation for more markup and information on calling dropdowns.

Text

Wrap strings of text in an element with .navbar-text, usually on a <p> tag for proper leading and color.

Optional display variations

Fix the navbar to the top or bottom of the viewport with an additional class on the outermost div, .navbar.

Fixed to top

Add .navbar-fixed-top and remember to account for the hidden area underneath it by adding at least 40px padding to the <body>. Be sure to add this after the core Bootstrap CSS and before the optional responsive CSS.

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

Fixed to bottom

Add .navbar-fixed-bottom instead.

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

Static top navbar

Create a full-width navbar that scrolls away with the page by adding .navbar-static-top. Unlike the .navbar-fixed-top class, you do not need to change any padding on the body.

<div class="navbar navbar-static-top">
  ...
</div>

Responsive navbar

To implement a collapsing responsive navbar, wrap your navbar content in a containing div, .nav-collapse.collapse, and add the navbar toggle button, .btn-navbar.

<div class="navbar">
  <div class="container">

    <!-- .btn-navbar is used as the toggle for collapsed navbar content -->
    <a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
    </a>

    <!-- Be sure to leave the brand out there if you want it shown -->
    <a class="brand" href="#">Project name</a>

    <!-- Everything you want hidden at 940px or less, place within here -->
    <div class="nav-collapse collapse">
      <!-- .nav, .navbar-search, .navbar-form, etc -->
    </div>

  </div>
</div>

Heads up! The responsive navbar requires the collapse plugin and responsive Bootstrap CSS file.

Inverted variation

Modify the look of the navbar by adding .navbar-inverse.

<div class="navbar navbar-inverse">
  ...
</div>

Examples

A single example shown as it might be displayed across multiple pages.

<ul class="breadcrumb">
  <li><a href="#">Home</a></li>
  <li><a href="#">Library</a></li>
  <li class="active">Data</li>
</ul>

Standard pagination

Simple pagination inspired by Rdio, great for apps and search results. The large block is hard to miss, easily scalable, and provides large click areas.

<div class="pagination">
  <ul>
    <li><a href="#">Prev</a></li>
    <li><a href="#">1</a></li>
    <li><a href="#">2</a></li>
    <li><a href="#">3</a></li>
    <li><a href="#">4</a></li>
    <li><a href="#">Next</a></li>
  </ul>
</div>

Options

Disabled and active states

Links are customizable for different circumstances. Use .disabled for unclickable links and .active to indicate the current page.

<div class="pagination">
  <ul>
    <li class="disabled"><a href="#">Prev</a></li>
    <li class="active"><a href="#">1</a></li>
    ...
  </ul>
</div>

You can optionally swap out active or disabled anchors for spans to remove click functionality while retaining intended styles.

<div class="pagination">
  <ul>
    <li class="disabled"><span>Prev</span></li>
    <li class="active"><span>1</span></li>
    ...
  </ul>
</div>

Sizes

Fancy larger or smaller pagination? Add .pagination-large, .pagination-small, or .pagination-mini for additional sizes.

<div class="pagination pagination-large">
  <ul>
    ...
  </ul>
</div>
<div class="pagination">
  <ul>
    ...
  </ul>
</div>
<div class="pagination pagination-small">
  <ul>
    ...
  </ul>
</div>
<div class="pagination pagination-mini">
  <ul>
    ...
  </ul>
</div>

Alignment

Add one of two optional classes to change the alignment of pagination links: .pagination-centered and .pagination-right.

<div class="pagination pagination-centered">
  ...
</div>

<div class="pagination pagination-right">
  ...
</div>

Pager

Quick previous and next links for simple pagination implementations with light markup and styles. It's great for simple sites like blogs or magazines.

Default example

By default, the pager centers links.

<ul class="pager">
  <li><a href="#">Previous</a></li>
  <li><a href="#">Next</a></li>
</ul>

Aligned links

Alternatively, you can align each link to the sides:

<ul class="pager">
  <li class="previous">
    <a href="#">&larr; Older</a>
  </li>
  <li class="next">
    <a href="#">Newer &rarr;</a>
  </li>
</ul>

Optional disabled state

Pager links also use the general .disabled utility class from the pagination.

<ul class="pager">
  <li class="previous disabled">
    <a href="#">&larr; Older</a>
  </li>
  ...
</ul>

Labels

Labels	Markup

Info	8	`<span class="badge badge-info">8</span>`
Inverse	10	`<span class="badge badge-inverse">10</span>`

Easily collapsible

For easy implementation, labels and badges will simply collapse (via CSS's :empty selector) when no content exists within.

Hero unit

A lightweight, flexible component to showcase key content on your site. It works well on marketing and content-heavy sites.

Hello, world!

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

Learn more

<div class="hero-unit">
  <h1>Heading</h1>
  <p>Tagline</p>
  <p>
    <a class="btn btn-primary btn-large">
      Learn more
    </a>
  </p>
</div>

Page header

A simple shell for an h1 to appropriately space out and segment sections of content on a page. It can utilize the h1's default small, element as well most other components (with additional styles).

<div class="page-header">
  <h1>Example page header <small>Subtext for header</small></h1>
</div>

Default thumbnails

By default, Bootstrap's thumbnails are designed to showcase linked images with minimal required markup.

<div class="row">
  <div class="span3">
    <a href="#" class="thumbnail">
      <img src="holder.js/260x180" alt="">
    </a>
  </div>
  ...
</div>

Custom content thumbnails

With a bit of extra markup, it's possible to add any kind of HTML content like headings, paragraphs, or buttons into thumbnails.

Thumbnail label

Cras justo odio, dapibus ac facilisis in, egestas eget quam. Donec id elit non mi porta gravida at eget metus. Nullam id dolor id nibh ultricies vehicula ut id elit.

      <p>Thumbnail caption...</p>
    </div>
  </div>
  ...
</div>

Default alert

Wrap any text and an optional dismiss button in .alert for a basic warning alert message.

Warning! Best check yo self, you're not looking too good.

<div class="alert">
  <button type="button" class="close" data-dismiss="alert">×</button>
  <strong>Warning!</strong> Best check yo self, you're not looking too good.
</div>

Dismiss buttons

Mobile Safari and Mobile Opera browsers, in addition to the data-dismiss="alert" attribute, require an href="#" for the dismissal of alerts when using an <a> tag.

<a href="#" class="close" data-dismiss="alert">×</a>

Alternatively, you may use a <button> element with the data attribute, which we have opted to do for our docs. When using <button>, you must include type="button" or your forms may not submit.

<button type="button" class="close" data-dismiss="alert">×</button>

Dismiss alerts via JavaScript

Use the alerts jQuery plugin for quick and easy dismissal of alerts.

Options

For longer messages, increase the padding on the top and bottom of the alert wrapper by adding .alert-block.

Warning!

Best check yo self, you're not looking too good. Nulla vitae elit libero, a pharetra augue. Praesent commodo cursus magna, vel scelerisque nisl consectetur et.

<div class="alert alert-block">
  <button type="button" class="close" data-dismiss="alert">×</button>
  <h4>Warning!</h4>
  Best check yo self, you're not...
</div>

Contextual alternatives

Add optional classes to change an alert's connotation.

Error or danger

Oh snap! Change a few things up and try submitting again.

<div class="alert alert-error">
  ...
</div>

Success

Well done! You successfully read this important alert message.

<div class="alert alert-success">
  ...
</div>

Information

Heads up! This alert needs your attention, but it's not super important.

<div class="alert alert-info">
  ...
</div>

Examples and markup

Basic

Default progress bar with a vertical gradient.

<div class="progress">
  <div class="bar" style="width: 60%;"></div>
</div>

Striped

Uses a gradient to create a striped effect. Not available in IE8.

<div class="progress progress-striped">
  <div class="bar" style="width: 20%;"></div>
</div>

Animated

Add .active to .progress-striped to animate the stripes right to left. Not available in all versions of IE.

<div class="progress progress-striped active">
  <div class="bar" style="width: 40%;"></div>
</div>

Stacked

Place multiple bars into the same .progress to stack them.

<div class="progress">
  <div class="bar bar-success" style="width: 35%;"></div>
  <div class="bar bar-warning" style="width: 20%;"></div>
  <div class="bar bar-danger" style="width: 10%;"></div>
</div>

Options

Additional colors

Progress bars use some of the same button and alert classes for consistent styles.

<div class="progress progress-info">
  <div class="bar" style="width: 20%"></div>
</div>
<div class="progress progress-success">
  <div class="bar" style="width: 40%"></div>
</div>
<div class="progress progress-warning">
  <div class="bar" style="width: 60%"></div>
</div>
<div class="progress progress-danger">
  <div class="bar" style="width: 80%"></div>
</div>

Striped bars

Similar to the solid colors, we have varied striped progress bars.

<div class="progress progress-info progress-striped">
  <div class="bar" style="width: 20%"></div>
</div>
<div class="progress progress-success progress-striped">
  <div class="bar" style="width: 40%"></div>
</div>
<div class="progress progress-warning progress-striped">
  <div class="bar" style="width: 60%"></div>
</div>
<div class="progress progress-danger progress-striped">
  <div class="bar" style="width: 80%"></div>
</div>

Browser support

Progress bars use CSS3 gradients, transitions, and animations to achieve all their effects. These features are not supported in IE8-9 or older versions of Firefox.

Versions earlier than Internet Explorer 10 and Opera 12 do not support animations.

Abstract object styles for building various types of components (like blog comments, Tweets, etc) that feature a left- or right-aligned image alongside textual content.

Default example

The default media allow to float a media object (images, video, audio) to the left or right of a content block.

Media heading

Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin commodo. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis. Fusce condimentum nunc ac nisi vulputate fringilla. Donec lacinia congue felis in faucibus.

Media heading

<div class="media">
  <a class="pull-left" href="#">
    <img class="media-object" data-src="holder.js/64x64">
  </a>
  <div class="media-body">
    <h4 class="media-heading">Media heading</h4>
    ...

    <!-- Nested media object -->
    <div class="media">
      ...
    </div>
  </div>
</div>

Media list

With a bit of extra markup, you can use media inside list (useful for comment threads or articles lists).

Media heading

Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin commodo. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis.

Nested media heading
Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin commodo. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis.

Nested media heading
Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin commodo. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis.

Nested media heading
Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin commodo. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis.
Media heading
Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin commodo. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis.

<ul class="media-list">
  <li class="media">
    <a class="pull-left" href="#">
      <img class="media-object" data-src="holder.js/64x64">
    </a>
    <div class="media-body">
      <h4 class="media-heading">Media heading</h4>
      ...

      <!-- Nested media object -->
      <div class="media">
        ...
     </div>
    </div>
  </li>
</ul>

Wells

Use the well as a simple effect on an element to give it an inset effect.

Look, I'm in a well!

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

Optional classes

Control padding and rounded corners with two optional modifier classes.

Look, I'm in a well!

<div class="well well-large">
  ...
</div>

Look, I'm in a well!

<div class="well well-small">
  ...
</div>

Close icon

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

<button class="close">&times;</button>

iOS devices require an href="#" for click events if you would rather use an anchor.

<a class="close" href="#">&times;</a>

Helper classes

Simple, focused classes for small display or behavior tweaks.

.pull-left

Float an element left

class="pull-left"

.pull-left {
  float: left;
}

.pull-right

Float an element right

class="pull-right"

.pull-right {
  float: right;
}

.muted

Change an element's color to #999

class="muted"

.muted {
  color: #999;
}

.clearfix

Clear the float on any element

class="clearfix"

.clearfix {
  *zoom: 1;
  &:before,
  &:after {
    display: table;
    content: "";
  }
  &:after {
    clear: both;
  }
}
