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

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.

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

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

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.

Two basic options, along with two more specific variations.

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

Combine sets of into a for more complex components.

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

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.

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

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

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

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.

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.

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

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.

All nav components here—tabs, pills, and lists—share the same base markup and styles through the .nav class.

Take a regular of links and add .nav-tabs:

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

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.

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

As tabs and pills are horizontal by default, just add a second class, .nav-stacked, to make them appear vertically stacked.

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

A simple and easy way to build groups of nav links with optional headers. They're best used in sidebars like the Finder in OS X.

Take a list of links and add class="nav nav-list":

Note For nesting within a nav list, include class="nav nav-list" on any nested .

Add a horizontal divider by creating an empty list item with the class .divider, like so:

Bring your tabs to life with a simple plugin to toggle between content via tabs. Bootstrap integrates tabbable tabs in four styles: top (default), right, bottom, and left.

To make tabs tabbable, create a .tab-pane with unique ID for every tab and wrap them in .tab-content.

I'm in Section 1.

Howdy, I'm in Section 2.

What up girl, this is Section 3.

I'm in Section 1.

Howdy, I'm in Section 2.

To make tabs fade in, add .fade to each .tab-pane.

All tabbable tabs are powered by our lightweight jQuery plugin. Read more about how to bring tabbable tabs to life on the JavaScript docs page.

Flip the order of the HTML and add a class to put tabs on the bottom.

I'm in Section A.

Howdy, I'm in Section B.

What up girl, this is Section C.

Swap the class to put tabs on the left.

I'm in Section A.

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.

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

Nav items are simple to add via unordered lists.

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

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.

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

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.

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

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

Wrap strings of text in an element with .navbar-text, usually on a

tag for proper leading and color.

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

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

Add .navbar-fixed-bottom instead.

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.

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.

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

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

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.

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

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

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

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

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

By default, the pager centers links.

Alternatively, you can align each link to the sides:

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

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

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).

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

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

Thumbnails (previously .media-grid up until v1.4) are great for grids of photos or videos, image search results, retail products, portfolios, and much more. They can be links or static content.

Thumbnail markup is simple—a ul with any number of li elements is all that is required. It's also super flexible, allowing for any type of content with just a bit more markup to wrap your contents.

Lastly, the thumbnails component uses existing grid system classes—like .span2 or .span3—for control of thumbnail dimensions.

As mentioned previously, the required markup for thumbnails is light and straightforward. Here's a look at the default setup for linked images:

For custom HTML content in thumbnails, the markup changes slightly. To allow block level content anywhere, we swap the for a like so:

Thumbnail caption...

Explore all your options with the various grid classes available to you. You can also mix and match different sizes.

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

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 tag.

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

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

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

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.

Add optional classes to change an alert's connotation.

Default progress bar with a vertical gradient.

Uses a gradient to create a striped effect. Not available in IE7-8.

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

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

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

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

Progress bars use CSS3 gradients, transitions, and animations to achieve all their effects. These features are not supported in IE7-9 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.

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

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

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.

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

Control padding and rounded corners with two optional modifier classes.

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

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

Simple, focused classes for small display or behavior tweaks.
