    <!-- Button trigger modal -->
    <button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
      Launch demo modal
    </button>

    <!-- Modal -->
    <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
      <div class="modal-dialog">
        <div class="modal-content">
          <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
            <h4 class="modal-title" id="myModalLabel">Modal title</h4>

          </div>
        </div><!-- /.modal-content -->
      </div><!-- /.modal-dialog -->
    </div><!-- /.modal -->

#### Make modals accessible

Be sure to add `role="dialog"` to `.modal`, `aria-labelledby="myModalLabel"` attribute to reference the modal title, and `aria-hidden="true"` to tell assistive technologies to skip the modal's DOM elements.

Additionally, you may give a description of your modal dialog with `aria-describedby` on `.modal`.

## Usage

### Via data attributes

Activate a modal without writing JavaScript. Set `data-toggle="modal"` on a controller element, like a button, along with a `data-target="#foo"` or `href="#foo"` to target a specific modal to toggle.

    <button type="button" data-toggle="modal" data-target="#myModal">Launch modal</button>

### Via JavaScript

Call a modal with id `myModal` with a single line of JavaScript:

    $('#myModal').modal(options)

### Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-backdrop=""`.

Name | type | default | description
--- | --- | --- | ---
backdrop | boolean | true | Includes a modal-backdrop element. Alternatively, specify `static` for a backdrop which doesn't close the modal on click.
keyboard | boolean | true | Closes the modal when escape key is pressed
show | boolean | true | Shows the modal when initialized.

remote

path

false

If a remote URL is provided, content will be loaded via jQuery's `load` method and injected into the root of the modal element. If you're using the data-api, you may alternatively use the `href` attribute to specify the remote source. An example of this is shown below:

    <a data-toggle="modal" href="remote.html" data-target="#modal">Click me</a>

### Methods

#### .modal(options)

Activates your content as a modal. Accepts an optional options `object`.

    $('#myModal').modal({
      keyboard: false
    })

#### .modal('toggle')

Manually toggles a modal.

    $('#myModal').modal('toggle')

#### .modal('show')

Manually opens a modal.

    $('#myModal').modal('show')

#### .modal('hide')

Manually hides a modal.

    $('#myModal').modal('hide')

### Events

Bootstrap's modal class exposes a few events for hooking into modal functionality.

Event Type | Description
--- | ---
show.bs.modal | This event fires immediately when the `show` instance method is called.
shown.bs.modal | This event is fired when the modal has been made visible to the user (will wait for CSS transitions to complete).
hide.bs.modal | This event is fired immediately when the `hide` instance method has been called.
hidden.bs.modal | This event is fired when the modal has finished being hidden from the user (will wait for CSS transitions to complete).

    $('#myModal').on('hidden.bs.modal', function () {
      // do something…
    })

# Dropdowns dropdown.js

## Examples

Add dropdown menus to nearly anything with this simple plugin, including the navbar, tabs, and pills.

### Within a navbar

### Within tabs

## Usage

### Via data attributes

Add `data-toggle="dropdown"` to a link or button to toggle a dropdown.

    <div class="dropdown">
      <a data-toggle="dropdown" href="#">Dropdown trigger</a>
      <ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
        ...
      </ul>
    </div>

To keep URLs intact, use the `data-target` attribute instead of `href="#"`.

    <div class="dropdown">
      <a id="dLabel" role="button" data-toggle="dropdown" data-target="#" href="/page.html">
        Dropdown <span class="caret"></span>
      </a>
      <ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
        ...
      </ul>
    </div>

### Via JavaScript

Call the dropdowns via JavaScript:

    $('.dropdown-toggle').dropdown()

### Options

None

### Methods

#### $().dropdown('toggle')

Toggles the dropdown menu of a given navbar or tabbed navigation.

### Events

Event Type | Description
--- | ---
show.bs.dropdown | This event fires immediately when the show instance method is called.
shown.bs.dropdown | This event is fired when the dropdown has been made visible to the user (will wait for CSS transitions, to complete).
hide.bs.dropdown | This event is fired immediately when the hide instance method has been called.
hidden.bs.dropdown | This event is fired when the dropdown has finished being hidden from the user (will wait for CSS transitions, to complete).

    $('#myDropdown').on('show.bs.dropdown', function () {
      // do something…
    })

# Togglable tabs tab.js

## Example tabs

Add quick, dynamic tab functionality to transition through panes of local content, even via dropdown menus.

#### Extends tabbed navigation

This plugin extends the tabbed navigation component to add tabbable areas.

## Usage

Enable tabbable tabs via JavaScript (each tab needs to be activated individually):

    $('#myTab a').click(function (e) {
      e.preventDefault()
      $(this).tab('show')
    })

You can activate individual tabs in several ways:

    $('#myTab a[href="#profile"]').tab('show') // Select tab by name
    $('#myTab a:first').tab('show') // Select first tab
    $('#myTab a:last').tab('show') // Select last tab
    $('#myTab li:eq(2) a').tab('show') // Select third tab (0-indexed)

### Markup

You can activate a tab or pill navigation without writing any JavaScript by simply specifying `data-toggle="tab"` or `data-toggle="pill"` on an element. Adding the `nav` and `nav-tabs` classes to the tab `ul` will apply the Bootstrap tab styling.

    <!-- Nav tabs -->
    <ul class="nav nav-tabs">
      <li><a href="#home" data-toggle="tab">Home</a></li>
      <li><a href="#profile" data-toggle="tab">Profile</a></li>
      <li><a href="#messages" data-toggle="tab">Messages</a></li>
      <li><a href="#settings" data-toggle="tab">Settings</a></li>
    </ul>

    <!-- Tab panes -->
    <div class="tab-content">
      <div class="tab-pane active" id="home">...</div>
      <div class="tab-pane" id="profile">...</div>
      <div class="tab-pane" id="messages">...</div>
      <div class="tab-pane" id="settings">...</div>
    </div>

### Fade effect

To make tabs fade in, add `.fade` to each `.tab-pane`. The first tab pane must also have `.in` to properly fade in initial content.

    <div class="tab-content">
      <div class="tab-pane fade in active" id="home">...</div>
      <div class="tab-pane fade" id="profile">...</div>
      <div class="tab-pane fade" id="messages">...</div>
      <div class="tab-pane fade" id="settings">...</div>
    </div>

### Methods

#### $().tab

Activates a tab element and content container. Tab should have either a `data-target` or an `href` targeting a container node in the DOM.

    <ul class="nav nav-tabs" id="myTab">
      <li class="active"><a href="#home">Home</a></li>
      <li><a href="#profile">Profile</a></li>
      <li><a href="#messages">Messages</a></li>
      <li><a href="#settings">Settings</a></li>
    </ul>

    <div class="tab-content">
      <div class="tab-pane active" id="home">...</div>
      <div class="tab-pane" id="profile">...</div>
      <div class="tab-pane" id="messages">...</div>
      <div class="tab-pane" id="settings">...</div>
    </div>

    <script>
      $(function () {
        $('#myTab a:last').tab('show')
      })
    </script>

### Events

Event Type | Description
--- | ---
show.bs.tab | This event fires on tab show, but before the new tab has been shown. Use `event.target` and `event.relatedTarget` to target the active tab and the previous active tab (if available) respectively.
shown.bs.tab | This event fires on tab show after a tab has been shown. Use `event.target` and `event.relatedTarget` to target the active tab and the previous active tab (if available) respectively.

    $('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
      e.target // activated tab
      e.relatedTarget // previous tab
    })

# Tooltips tooltip.js

## Examples

Inspired by the excellent jQuery.tipsy plugin written by Jason Frame; Tooltips are an updated version, which don't rely on images, use CSS3 for animations, and data-attributes for local title storage.

Hover over the links below to see tooltips:

Tight pants next level keffiyeh you probably haven't heard of them. Photo booth beard raw denim letterpress vegan messenger bag stumptown. Farm-to-table seitan, mcsweeney's fixie sustainable quinoa 8-bit american apparel have a terry richardson vinyl chambray. Beard stumptown, cardigans banh mi lomo thundercats. Tofu biodiesel williamsburg marfa, four loko mcsweeney's cleanse vegan chambray. A really ironic artisan whatever keytar, scenester farm-to-table banksy Austin twitter handle freegan cred raw denim single-origin coffee viral.

### Four directions

#### Tooltips in button groups and input groups require special setting

When using tooltips on elements within a `.btn-group` or an `.input-group`, you'll have to specify the option `container: 'body'` (documented below) to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the tooltip is triggered).

#### Tooltips on disabled elements require wrapper elements

To add a tooltip to a `disabled` or `.disabled` element, put the element inside of a `<div>` or `<span>`, and apply the tooltip to that element instead.

## Usage

Trigger the tooltip via JavaScript:

    $('#example').tooltip(options)

### Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-animation=""`.

Name | type | default | description
--- | --- | --- | ---
animation | boolean | true | apply a CSS fade transition to the tooltip
html | boolean | false | Insert HTML into the tooltip. If false, jQuery's `text` method will be used to insert content into the DOM. Use text if you're worried about XSS attacks.
placement | string | function | 'top' | how to position the tooltip - top | bottom | left | right | auto. When "auto" is specified, it will dynamically reorient the tooltip. For example, if placement is "auto left", the tooltip will display to the left when possible, otherwise it will display right.
selector | string | false | If a selector is provided, tooltip objects will be delegated to the specified targets.
title | string | function | '' | default title value if `title` attribute isn't present
trigger | string | 'hover focus' | how tooltip is triggered - click | hover | focus | manual. You may pass multiple triggers; separate them with a space.
delay | number | object | 0 | delay showing and hiding the tooltip (ms) - does not apply to manual trigger type If a number is supplied, delay is applied to both hide/show Object structure is: `delay: { show: 500, hide: 100 }`
container | string | false | false | Appends the tooltip to a specific element. Example: `container: 'body'`

#### Data attributes for individual tooltips

Options for individual tooltips can alternatively be specified through the use of data attributes, as explained above.

### Markup

    <a href="#" data-toggle="tooltip" title="first tooltip">Hover over me</a>

### Methods

#### $().tooltip(options)

Attaches a tooltip handler to an element collection.

#### .tooltip('show')

Reveals an element's tooltip.

    $('#element').tooltip('show')

#### .tooltip('hide')

Hides an element's tooltip.

    $('#element').tooltip('hide')

#### .tooltip('toggle')

Toggles an element's tooltip.

    $('#element').tooltip('toggle')

#### .tooltip('destroy')

Hides and destroys an element's tooltip.

    $('#element').tooltip('destroy')

### Events

Event Type | Description
--- | ---
show.bs.tooltip | This event fires immediately when the `show` instance method is called.
shown.bs.tooltip | This event is fired when the tooltip has been made visible to the user (will wait for CSS transitions to complete).
hide.bs.tooltip | This event is fired immediately when the `hide` instance method has been called.
hidden.bs.tooltip | This event is fired when the tooltip has finished being hidden from the user (will wait for CSS transitions to complete).

    $('#myTooltip').on('hidden.bs.tooltip', function () {
      // do something…
    })

# Popovers popover.js

## Examples

Add small overlays of content, like those on the iPad, to any element for housing secondary information.

#### Plugin dependency

Popovers require the tooltip plugin to be included in your version of Bootstrap.

#### Popovers in button groups and input groups require special setting

When using popovers on elements within a `.btn-group` or an `.input-group`, you'll have to specify the option `container: 'body'` (documented below) to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the popover is triggered).

#### Popovers on disabled elements require wrapper elements

To add a popover to a `disabled` or `.disabled` element, put the element inside of a `<div>` or `<span>`, and apply the popover to that element instead.

### Static popover

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

### Popover top

Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.

### Popover right

Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.

### Popover bottom

Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.

### Popover left

Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.

### Live demo

#### Four directions

## Usage

Enable popovers via JavaScript:

    $('#example').popover(options)

### Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-animation=""`.

Name | type | default | description
--- | --- | --- | ---
animation | boolean | true | apply a CSS fade transition to the tooltip
html | boolean | false | Insert HTML into the popover. If false, jQuery's `text` method will be used to insert content into the DOM. Use text if you're worried about XSS attacks.
placement | string | function | 'right' | how to position the popover - top | bottom | left | right | auto. When "auto" is specified, it will dynamically reorient the popover. For example, if placement is "auto left", the tooltip will display to the left when possible, otherwise it will display right.
selector | string | false | if a selector is provided, tooltip objects will be delegated to the specified targets if a selector is provided, tooltip objects will be delegated to the specified targets. in practice, this is used to enable dynamic HTML content to have popovers added. See this and an informative example.
trigger | string | 'click' | how popover is triggered - click | hover | focus | manual
title | string | function | '' | default title value if `title` attribute isn't present
content | string | function | '' | default content value if `data-content` attribute isn't present
delay | number | object | 0 | delay showing and hiding the popover (ms) - does not apply to manual trigger type If a number is supplied, delay is applied to both hide/show Object structure is: `delay: { show: 500, hide: 100 }`
container | string | false | false | Appends the popover to a specific element. Example: `container: 'body'`. This option is particularly useful in that it allows you to position the popover in the flow of the document near the triggering element - which will prevent the popover from floating away from the triggering element during a window resize.

#### Data attributes for individual popovers

Options for individual popovers can alternatively be specified through the use of data attributes, as explained above.

### Markup

For performance reasons, the Tooltip and Popover data-apis are opt in. If you would like to use them just specify a selector option.

### Methods

#### $().popover(options)

Initializes popovers for an element collection.

#### .popover('show')

Reveals an elements popover.

    $('#element').popover('show')

#### .popover('hide')

#### .popover('toggle')

Toggles an elements popover.

    $('#element').popover('toggle')

#### .popover('destroy')

Hides and destroys an element's popover.

    $('#element').popover('destroy')

### Events

You can also use the plugin without the accordion markup. Make a button toggle the expanding and collapsing of another element.

    <button type="button" class="btn btn-danger" data-toggle="collapse" data-target="#demo">
      simple collapsible
    </button>

    <div id="demo" class="collapse in">...</div>

## Usage

### Via data attributes

Just add `data-toggle="collapse"` and a `data-target` to element to automatically assign control of a collapsible element. The `data-target` attribute accepts a CSS selector to apply the collapse to. Be sure to add the class `collapse` to the collapsible element. If you'd like it to default open, add the additional class `in`.

To add accordion-like group management to a collapsible control, add the data attribute `data-parent="#selector"`. Refer to the demo to see this in action.

### Via JavaScript

Enable manually with:

    $(".collapse").collapse()

### Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-parent=""`.

Name | type | default | description
--- | --- | --- | ---
parent | selector | false | If selector then all collapsible elements under the specified parent will be closed when this collapsible item is shown. (similar to traditional accordion behavior - this dependent on the `accordion-group` class)
toggle | boolean | true | Toggles the collapsible element on invocation

### Methods

#### .collapse(options)

Activates your content as a collapsible element. Accepts an optional options `object`.

    $('#myCollapsible').collapse({
      toggle: false
    })

#### .collapse('toggle')

Toggles a collapsible element to shown or hidden.

#### .collapse('show')

Shows a collapsible element.

#### .collapse('hide')

Hides a collapsible element.

### Events

Bootstrap's collapse class exposes a few events for hooking into collapse functionality.

Event Type | Description
--- | ---
show.bs.collapse | This event fires immediately when the `show` instance method is called.
shown.bs.collapse | This event is fired when a collapse element has been made visible to the user (will wait for CSS transitions to complete).
hide.bs.collapse | This event is fired immediately when the `hide` method has been called.
hidden.bs.collapse | This event is fired when a collapse element has been hidden from the user (will wait for CSS transitions to complete).

    $('#myCollapsible').on('hidden.bs.collapse', function () {
      // do something…
    })

# Carousel carousel.js

## Examples

The slideshow below shows a generic plugin and component for cycling through elements like a carousel.

    <div id="carousel-example-generic" class="carousel slide">
      <!-- Indicators -->
      <ol class="carousel-indicators">
        <li data-target="#carousel-example-generic" data-slide-to="0" class="active"></li>
        <li data-target="#carousel-example-generic" data-slide-to="1"></li>
        <li data-target="#carousel-example-generic" data-slide-to="2"></li>
      </ol>

      <!-- Wrapper for slides -->
      <div class="carousel-inner">
        <div class="item active">
          <img src="..." alt="...">
          <div class="carousel-caption">
            ...
          </div>
        </div>
        ...
      </div>

      <!-- Controls -->
      <a class="left carousel-control" href="#carousel-example-generic" data-slide="prev">
        <span class="glyphicon glyphicon-chevron-left"></span>
      </a>
      <a class="right carousel-control" href="#carousel-example-generic" data-slide="next">
        <span class="glyphicon glyphicon-chevron-right"></span>
      </a>
    </div>

#### Transition animations not supported in Internet Explorer 8 & 9

Bootstrap exclusively uses CSS3 for its animations, but Internet Explorer 8 & 9 don't support the necessary CSS properties. Thus, there are no slide transition animations when using these browsers. We have intentionally decided not to include jQuery-based fallbacks for the transitions.

### Optional captions

Add captions to your slides easily with the `.carousel-caption` element within any `.item`. Place just about any optional HTML within there and it will be automatically aligned and formatted.

### First slide label

Nulla vitae elit libero, a pharetra augue mollis interdum.

### Second slide label

Lorem ipsum dolor sit amet, consectetur adipiscing elit.

### Third slide label

Praesent commodo cursus magna, vel scelerisque nisl consectetur.

    <div class="item active">
      <img src="..." alt="...">
      <div class="carousel-caption">
        <h3>...</h3>
        <p>...</p>
      </div>
    </div>

#### Accessibility issue

The carousel component is generally not compliant with accessibility standards. If you need to be compliant, please consider other options for presenting your content.

## Usage

### Via data attributes

Use data attributes to easily control the position of the carousel. `data-slide` accepts the keywords `prev` or `next`, which alters the slide position relative to its current position. Alternatively, use `data-slide-to` to pass a raw slide index to the carousel `data-slide-to="2"`, which shifts the slide position to a particular index beginning with `0`.

The `data-ride="carousel"` attribute is used to mark a carousel as animating starting at page load.

### Via JavaScript

Call carousel manually with:

    $('.carousel').carousel()

### Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-interval=""`.

Name | type | default | description
--- | --- | --- | ---
interval | number | 5000 | The amount of time to delay between automatically cycling an item. If false, carousel will not automatically cycle.
pause | string | "hover" | Pauses the cycling of the carousel on mouseenter and resumes the cycling of the carousel on mouseleave.
wrap | boolean | true | Whether the carousel should cycle continuously or have hard stops.

### Methods

#### .carousel(options)

Initializes the carousel with an optional options `object` and starts cycling through items.

    $('.carousel').carousel({
      interval: 2000
    })

#### .carousel('cycle')

Cycles through the carousel items from left to right.

#### .carousel('pause')

Stops the carousel from cycling through items.

#### .carousel(number)

Cycles the carousel to a particular frame (0 based, similar to an array).

#### .carousel('prev')

Cycles to the previous item.

#### .carousel('next')

Cycles to the next item.

### Events

Bootstrap's carousel class exposes two events for hooking into carousel functionality.

Event Type | Description
--- | ---
slide.bs.carousel | This event fires immediately when the `slide` instance method is invoked.
slid.bs.carousel | This event is fired when the carousel has completed its slide transition.

    $('#myCarousel').on('slide.bs.carousel', function () {
      // do something…
    })
