Toggleable, contextual menu for displaying lists of links. Made interactive with the dropdown JavaScript plugin.
Wrap the dropdown's trigger and the dropdown menu within .dropdown
, or another element that declares position: relative;
. Then add the menu's HTML.
Add .pull-right
to a .dropdown-menu
to right align the dropdown menu.
Add a header to label sections of actions in any dropdown menu.
{% highlight html %} {% endhighlight %}Add .disabled
to a <li>
in the dropdown to disable the link.
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.
When using tooltips or popovers on elements within a .btn-group
, you'll have to specify the option container: 'body'
to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the tooltip or popover is triggered).
Wrap a series of buttons with .btn
in .btn-group
.
Combine sets of <div class="btn-group">
into a <div class="btn-toolbar">
for more complex components.
Instead of applying button sizing classes to every button in a group, just add .btn-group-*
to the .btn-group
.
Place a .btn-group
within another .btn-group
when you want dropdown menus mixed with a series of buttons.
Make a set of buttons appear vertically stacked rather than horizontally.
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.
Use any button to trigger a dropdown menu by placing it within a .btn-group
and providing the proper menu markup.
Button dropdowns require the dropdown plugin to be included in your version of Bootstrap.
Turn a button into a dropdown toggle with some basic markup changes.
Similarly, create split button dropdowns with the same markup changes, only with a separate button.
Button dropdowns work with buttons of all sizes.
Trigger dropdown menus above elements by adding .dropup
to the parent.
Extend form controls by adding text or buttons before, after, or on both sides of any text-based input. Use .input-group
with an .input-group-addon
to prepend or append elements to a .form-control
.
Avoid using <select>
elements here as they cannot be fully styled in WebKit browsers.
When using tooltips or popovers on elements within an .input-group
, you'll have to specify the option container: 'body'
to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the tooltip or popover is triggered).
Add the relative form sizing classes to the .input-group
itself and contents within will automatically resizeāno need for repeating the form control size classes on each element.
Place any checkbox or radio option within an input group's addon instead of text.
{% highlight html %}Buttons in input groups are a bit different and require one extra level of nesting. Instead of .input-group-addon
, you'll need to use .input-group-btn
to wrap the buttons. This is required due to default browser styles that cannot be overridden.
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.
Note the .nav-tabs
class requires the .nav
base class.
Take that same HTML, but use .nav-pills
instead:
Pills are also vertically stackable. Just add .nav-stacked
.
Easily make tabs or pills equal widths of their parent with .nav-justified
.
For any nav component (tabs, pills, or list), add .disabled
for gray links and no hover effects.
This class will only change the <a>
's appearance, not its functionality. Use custom JavaScript to disable links here.
To align nav links, use the .pull-left
or .pull-right
utility classes. Both classes will add a CSS float in the specified direction.
Add dropdown menus with a little extra HTML and the dropdowns JavaScript plugin.
Navbars are responsive meta components that serve as navigation headers for your application or site. They begin collapsed (and are toggleable) in mobile views and become horizontal as the available viewport width increases.
Depending on the content in your navbar, you might need to change the point at which your navbar switches between collapsed and horizontal mode. Customize the @grid-float-breakpoint
variable or add your own media query.
The responsive navbar requires the collapse plugin to be included in your version of Bootstrap.
Be sure to add a role="navigation"
to every navbar to help with accessibility.
For buttons not residing in a <form>
, add this class to vertically center buttons within a navbar.
Wrap strings of text in an element with .navbar-text
, usually on a <p>
tag for proper leading and color.
For folks using standard links that are not within the regular navbar navigation component, use the .navbar-link
class to add the proper colors for the default and inverse navbar options.
Align nav links, forms, buttons, or text, using the .navbar-left
or .navbar-right
utility classes. Both classes will add a CSS float in the specified direction. For example, to align nav links, put them in a separate <ul>
with the respective utility class applied.
These classes are mixin-ed versions of .pull-left
and .pull-right
, but they're scoped to media queries for easier handling of navbar components across device sizes.
Add .navbar-fixed-top
.
The fixed navbar will overlay your other content, unless you add padding
to the top of the <body>
. Try out your own values or use our snippet below. Tip: By default, the navbar is 50px high.
Make sure to include this after the core Bootstrap CSS.
Add .navbar-fixed-bottom
instead.
The fixed navbar will overlay your other content, unless you add padding
to the bottom of the <body>
. Try out your own values or use our snippet below. Tip: By default, the navbar is 50px high.
Make sure to include this after the core Bootstrap CSS.
Create a full-width navbar that scrolls away with the page by adding .navbar-static-top
. Unlike the .navbar-fixed-*
classes, you do not need to change any padding on the body
.
Modify the look of the navbar by adding .navbar-inverse
.
Indicate the current page's location within a navigational hierarchy.
Separators are automatically added in CSS through :before
and content
.
Provide pagination links for your site or app with the multi-page pagination component, or the simpler pager alternative.
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.
{% highlight html %} {% endhighlight %}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 <span>
to remove click functionality while retaining intended styles.
Fancy larger or smaller pagination? Add .pagination-lg
or .pagination-sm
for additional sizes.
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.
{% highlight html %} {% endhighlight %}Alternatively, you can align each link to the sides:
{% highlight html %} {% endhighlight %}Pager links also use the general .disabled
utility class from the pagination.
Add any of the below mentioned modifier classes to change the appearance of a label.
Easily highlight new or unread items by adding a <span class="badge">
to links, Bootstrap navs, and more.
When there are no new or unread items, badges will simply collapse (via CSS's :empty
selector) provided no content exists within.
Badges won't self collapse in Internet Explorer 8 because it lacks support for the :empty
selector.
Built-in styles are included for placing badges in active states in pill and list navigations.
A lightweight, flexible component that can optional extend the entire viewport to showcase key content on your site. To make the jumbotron full width, don't include it within a .container
. Placing it within a container will keep it at the width of the rest of your content and provide rounded corners.
This is a simple hero unit, a simple jumbotron-style component for calling extra attention to featured content or information.
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 as most other components (with additional styles).
Extend Bootstrap's grid system with the thumbnail component to easily display grids of images, videos, text, and more.
By default, Bootstrap's thumbnails are designed to showcase linked images with minimal required markup.
{% highlight html %} {% endhighlight %}With a bit of extra markup, it's possible to add any kind of HTML content like headings, paragraphs, or buttons into thumbnails.
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.
Wrap any text and an optional dismiss button in .alert
for a basic warning alert message.
Add optional classes to change an alert's connotation.
Build on any alert by adding an optional .alert-dismissable
and close button.
Be sure to use the <button>
element with the data-dismiss="alert"
data attribute.
Use the .alert-link
utility class to quickly provide matching colored links within any alert.
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 Internet Explorer 9 and below or older versions of Firefox. Opera 12 does not support animations.
Default progress bar with a vertical gradient.
Progress bars use some of the same button and alert classes for consistent styles.
Uses a gradient to create a striped effect. Not available in IE8.
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.
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.
List groups are a flexible and powerful component for displaying not only simple lists of elements, but complex ones with custom content.
The most basic list group is simply an unordered list with list items, and the proper classes. Build upon it with the options that follow, or your own CSS as needed.
Add the badges component to any list group item and it will automatically be positioned on the right.
Linkify list group items by using anchor tags instead of list items (that also means a parent <div>
instead of an <ul>
). No need for individual parents around each element.
Add nearly any HTML within, even for linked list groups like the one below.
Donec id elit non mi porta gravida at eget metus. Maecenas sed diam eget risus varius blandit.
Donec id elit non mi porta gravida at eget metus. Maecenas sed diam eget risus varius blandit.
Donec id elit non mi porta gravida at eget metus. Maecenas sed diam eget risus varius blandit.
While not always necessary, sometimes you need to put your DOM in a box. For those situations, try the panel component.
By default, all the .panel
does is apply some basic border and padding to contain some content.
Easily add a heading container to your panel with .panel-heading
. You may also include any <h1>
-<h6>
with a .panel-title
class to add a pre-styled heading.
Wrap buttons or secondary text in .panel-footer
. Note that panel footers do not inherit colors and borders when using contextual variations as they are not meant to be in the foreground.
Like other components, easily make a panel more meaningful to a particular context by adding any of the contextual state classes.
Easily include full-width list groups within any panel.
Some default panel content here. Nulla vitae elit libero, a pharetra augue. Aenean lacinia bibendum nulla sed consectetur. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum. Nullam id dolor id nibh ultricies vehicula ut id elit.
...
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.
