# Dropdown menus

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

### Example

Wrap the dropdown's trigger and the dropdown menu within `.dropdown`, or another element that declares `position: relative;`. Then add the menu's HTML.

    <div class="dropdown">
      <!-- Link or button to toggle dropdown -->
      <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>
    </div>

### 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>

### Disabled menu options

Add `.disabled` to a `<li>` in the dropdown to disable the link.

    <ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu">
      <li><a tabindex="-1" href="#">Regular link</a></li>
      <li class="disabled"><a tabindex="-1" href="#">Disabled link</a></li>
      <li><a tabindex="-1" href="#">Another link</a></li>
    </ul>

# Button groups

Group a series of buttons together on a single line with the button group. Add on optional JavaScript radio and checkbox style behavior with our buttons plugin.

### Single button group

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

    <div class="btn-group">
      <button class="btn">Left</button>
      <button class="btn">Middle</button>
      <button class="btn">Right</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>

### Justified button groups

Make a group of buttons stretch at the same size to span the entire width of its parent. This only works with `<a>` elements as the `<button>` doesn't pick up these styles.

Left Right Middle

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

# Button dropdown menus

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

### Single or split button

Turn a button into dropdown toggle, or add a second button to toggle the dropdown while retaining the primary button action.

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

    <-- Split button -->
    <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>

### Works with all button sizes

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

### Dropup buttons

Trigger dropdown menus above elements by adding `.dropup` to the parent.

    <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

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>

# Navbar

## 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 the appropriate class to `<li>` elements between links. Dividers will be horizontal to start, but at resolutions above 768px they become vertical with the navigation.

    <ul class="nav">
      ...
      <li class="divider"></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="pull-left">
      <input type="text" style="width: 200px;">
      <button type="submit" class="btn">Submit</button>
    </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>

# Breadcrumbs

Indicate the current page's location within a navigational hierarchy.

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

# Pagination

Provide pagination links for your site or app with the multi-page pagination component, or the simpler pager alternative.

## 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.

- «
- 1
- 2
- 3
- 4
- 5
- »

    <ul class="pagination">
      <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="#">5</a></li>
      <li><a href="#">Next</a></li>
    </ul>

### Disabled and active states

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

- «
- 1
- 2
- 3
- 4
- 5
- »

    <ul class="pagination">
      <li class="disabled"><a href="#">&laquo;</a></li>
      <li class="active"><a href="#">1</a></li>
      ...
    </ul>

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

    <ul class="pagination">
      <li class="disabled"><span>&laquo;</span></li>
      <li class="active"><span>1</span></li>
      ...
    </ul>

### Sizes

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

- 3

- 5
- »

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

## 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.

- Previous
- Next

    <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:

- ← Older
- Newer →

    <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.

- ← Older
- Newer →

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

# Counters

Easily highlight new or unread items by adding a `<span class="counter">` to links, Bootstrap navs, and more.

Inbox 42

    <a href="#">
      Inbox
      <span class="counter">42</span>
    </a>

#### Self collapsing

When there are no new or unread items, counters will simply collapse (via CSS's `:empty` selector) provided no content exists within.

#### Adapts to active nav states

Built-in styles are included for placing counters in active states in pill and list navigations.

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

# Typographic components

## Jumbotron

    <div class="jumbotron">
      <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).

# Example page header Subtext for header

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

# Thumbnails

Extend Bootstrap's grid system with the thumbnail component to easily display grids of images, videos, text, and more.

### 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>

# Alerts

Provide contextual feedback messages for typical user actions with the handful of available and flexible alert messages. For inline dismissal, use the alerts jQuery plugin.

### Default alert

Wrap any text and an optional dismiss button in `.alert` for a basic warning alert message. To ensure proper behavior across all devices, be sure to use `<button>` element with the `data-dismiss="alert"` data attribute.

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

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

### Block alerts

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">&times;</button>
      <h4>Warning!</h4>
      Best check yo self, you're not...
    </div>

### Contextual alternatives

Add optional classes to change an alert's connotation.

Oh snap! Change a few things up and try submitting again.
Well done! You successfully read this important alert message.
Heads up! This alert needs your attention, but it's not super important.

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

# Progress bars

Provide up-to-date feedback on the progress of a workflow or action with simple yet flexible progress bars.

Progress bars use CSS3 transitions and animations to achieve some of their effects. These features are not supported in IE8-9 or older versions of Firefox. Internet Explorer 10 and below, as well as Opera 12, do not support animations.

### Basic

Default progress bar with a vertical gradient.

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

### Additional colors

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

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

### Striped

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

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

### Stacked

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

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

# Media object

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

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

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.

    <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

# Miscellaneous Lightweight utility components

## 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. Utilizes the micro clearfix as popularized by Nicolas Gallagher.

    class="clearfix"

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