About transitions

For simple transition effects, include transition.js once alongside the other JS files. If you're using the compiled (or minified) bootstrap.js, there is no need to include this—it's already there.

What's inside

Transition.js is a basic helper for transitionEnd events as well as a CSS transition emulator. It's used by the other plugins to check for CSS transition support and to catch hanging transitions.

Modals are streamlined, but flexible, dialog prompts with the minimum required functionality and smart defaults.

Overlapping modals not supported

Be sure not to open a modal while another is still visible. Showing more than one modal at a time requires custom code.

Mobile device caveats

There are some caveats regarding using modals on mobile devices. See our browser support docs for details.

Static example

A rendered modal with header, body, and set of actions in the footer.

<div class="modal fade">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
        <h4 class="modal-title">Modal title</h4>
      </div>
      <div class="modal-body">
        <p>One fine body…</p>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div><!-- /.modal-content -->
  </div><!-- /.modal-dialog -->
</div><!-- /.modal -->

Live demo

Toggle a modal via JavaScript by clicking the button below. It will slide down and fade in from the top of the page.

<!-- 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">×</button>
        <h4 class="modal-title" id="myModalLabel">Modal title</h4>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </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.

The modal plugin toggles your hidden content on demand, via data attributes or JavaScript. It also adds .model-open to the <body> to override default scrolling behavior and generates a .modal-backdrop to provide a click area for dismissing shown modals when clicking outside the modal.

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 or the string `'static'`	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. Returns to the caller before the modal has actually been shown or hidden (i.e. before the shown.bs.modal or hidden.bs.modal event occurs).

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

.modal('show')

Manually opens a modal. Returns to the caller before the modal has actually been shown (i.e. before the shown.bs.modal event occurs).

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

.modal('hide')

Manually hides a modal. Returns to the caller before the modal has actually been hidden (i.e. before the hidden.bs.modal event occurs).

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

Events

The 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. If caused by a click, the clicked element is available as the `relatedTarget` property of the event.
shown.bs.modal	This event is fired when the modal has been made visible to the user (will wait for CSS transitions to complete). If caused by a click, the clicked element is available as the `relatedTarget` property of the event.
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 (e) {
  // do something...
})

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

Within tabs

Via data attributes or JavaScript, the dropdown plugin toggles hidden content (dropdown menus) by toggling the .open class on the parent list item. When opened, the plugin also adds .dropdown-backdrop as a click area for closing dropdown menus when clicking outside the menu.

Via data atributes

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.

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…
})

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, while adding the nav and nav-pills classes will apply pill 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" 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>
 
<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
})

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:

Four directions

Opt-in functionality

For performance reasons, the Tooltip and Popover data-apis are opt-in, meaning you must initialize them yourself.

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> and apply the tooltip to that <div> instead.

The tooltip plugin generates content and markup on demand, and by default places tooltips after their trigger element.

Trigger the tooltip via JavaScript:

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

Markup

The generated markup of a tooltip is rather simple, though it does require a position (by default, set to top by the plugin).

<div class="tooltip">
  <div class="tooltip-inner">
    Tooltip!
  </div>
  <div class="tooltip-arrow"></div>
</div>

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.

<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…
})

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.

Opt-in functionality

For performance reasons, the Tooltip and Popover data-apis are opt-in, meaning you must initialize them yourself.

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> and apply the popover to that <div> instead.

Static popover

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

Demo

Four directions

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 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 popover. For example, if placement is "auto left", the popover will display to the left when possible, otherwise it will display right.
selector	string	false	if a selector is provided, popover 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
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 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.

Methods

$().popover(options)

Initializes popovers for an element collection.

.popover('show')

Reveals an element's popover.

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

.popover('hide')

Hides an element's popover.

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

.popover('toggle')

Toggles an element's popover.

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

.popover('destroy')

Hides and destroys an element's popover.

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

Events

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

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

Examples

Add dismiss functionality to all alert messages with this plugin.

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

Oh snap! You got an error!

Change this and that and try again. Duis mollis, est non commodo luctus, nisi erat porttitor ligula, eget lacinia odio sem nec elit. Cras mattis consectetur purus sit amet fermentum.

Usage

Enable dismissal of an alert via JavaScript:

$(".alert").alert()

Markup

Just add data-dismiss="alert" to your close button to automatically give an alert close functionality.

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

Methods

$().alert()

Wraps all alerts with close functionality. To have your alerts animate out when closed, make sure they have the .fade and .in class already applied to them.

.alert('close')

Closes an alert.

$(".alert").alert('close')

Events

Event Type	Description
close.bs.alert	This event fires immediately when the close instance method is called.
closed.bs.alert	This event is fired when the alert has been closed (will wait for CSS transitions to complete).

$('#my-alert').bind('closed.bs.alert', function () {
  // do something…
})

Examples

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

Stateful

Add data-loading-text="Loading..." to use a loading state on a button.

<button type="button" data-loading-text="Loading..." class="btn btn-primary">
  Loading state
</button>

Single toggle

Add data-toggle="button" to activate toggling on a single button.

<button type="button" class="btn btn-primary" data-toggle="button">Single toggle</button>

Checkbox

Add data-toggle="buttons" to a group of checkboxes for checkbox style toggling on btn-group.

Option 1 Option 2 Option 3

<div class="btn-group" data-toggle="buttons">
  <label class="btn btn-primary">
    <input type="checkbox"> Option 1
  </label>
  <label class="btn btn-primary">
    <input type="checkbox"> Option 2
  </label>
  <label class="btn btn-primary">
    <input type="checkbox"> Option 3
  </label>
</div>

Radio

Add data-toggle="buttons" to a group of radio inputs for radio style toggling on btn-group.

Option 1 Option 2 Option 3

<div class="btn-group" data-toggle="buttons">
  <label class="btn btn-primary">
    <input type="radio" name="options" id="option1"> Option 1
  </label>
  <label class="btn btn-primary">
    <input type="radio" name="options" id="option2"> Option 2
  </label>
  <label class="btn btn-primary">
    <input type="radio" name="options" id="option3"> Option 3
  </label>
</div>

Usage

Enable buttons via JavaScript:

$('.btn').button()

Markup

Data attributes are integral to the button plugin. Check out the example code below for the various markup types.

Options

None

Methods

$().button('toggle')

Toggles push state. Gives the button the appearance that it has been activated.

Auto toggling

You can enable auto toggling of a button by using the data-toggle attribute.

<button type="button" class="btn" data-toggle="button">...</button>

.button('loading')

Sets button state to loading - disables button and swaps text to loading text. Loading text should be defined on the button element using the data attribute data-loading-text.

<button type="button" class="btn" data-loading-text="loading stuff...">...</button>

Cross-browser compatibility

Firefox persists the disabled state across page loads. A workaround for this is to use autocomplete="off".

.button('reset')

Resets button state - swaps text to original text.

.button(string)

Resets button state - swaps text to any data defined text state.

<button type="button" class="btn" data-complete-text="finished!" >...</button>
<script>
  $('.btn').button('complete')
</script>

Usage

The collapse plugin utilizes a few classes to handle the heavy lifting:

.collapse hides the content
.collapse.in shows the content
.collapsing is added when the transition starts, and removed when it finishes

These classes can be found in component-animations.less.

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

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…
})

Examples

<div id="carousel-example-generic" class="carousel slide" data-ride="carousel">

    <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">

      <img src="..." alt="...">
      <div class="carousel-caption">
        ...
      </div>
    </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…
})

Example

The subnavigation on the left is a live demo of the affix plugin.

Usage

Use the affix plugin via data attributes or manually with your own JavaScript. In both situations, you must provide CSS for the positioning of your content.

Positioning via CSS

The affix plugin toggles between three classes, each representing a particular state: .affix, .affix-top, and .affix-bottom. You must provide the styles for these classes yourself (independent of this plugin) to handle the actual positions.

Here's how the affix plugin works:

To start, the plugin adds .affix-top to indicate the element is in it's top-most position. At this point no CSS positioning is required.
Scrolling past the element you want affixed should trigger the actual affixing. This is where .affix replaces .affix-top and sets position: fixed; (provided by Bootstrap's code CSS).
If a bottom offset is defined, scrolling past that should replace .affix with .affix-bottom. Since offsets are optional, setting one requires you to set the appropriate CSS. In this case, add position: absolute; when necessary. The plugin uses the data attribute or JavaScript option to determine where to position the elemtn from there.

Follow the above steps to set your CSS for either of the usage options below.

Via data attributes

To easily add affix behavior to any element, just add data-spy="affix" to the element you want to spy on. Use offsets to define when to toggle the pinning of an element.

<div data-spy="affix" data-offset-top="60" data-offset-bottom="200">
  ...
</div>

Via JavaScript

Call the affix plugin via JavaScript:

$('#myAffix').affix({
  offset: {
    top: 100
  , bottom: function () {
      return (this.bottom = $('.bs-footer').outerHeight(true))
    }
  }
})

Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-offset-top="200".

Name	type	default	description
offset	Number \| function \| object	10	Pixels to offset from screen when calculating position of scroll. If a single number is provided, the offset will be applied in both top and bottom directions. To provide a unique, bottom and top offset just provide an object `offset: { top: 10 }` or `offset: { top: 10, bottom: 5 }`. Use a function when you need to dynamically calculate an offset.
