Includes 200 glyphs in font format from the Glyphicon Halflings set. Glyphicons Halflings are normally not available for free, but their creator has made them available for Bootstrap free of cost. As a thank you, we only ask that you include a link back to Glyphicons whenever possible.
For performance reasons, all icons require a base class and individual icon class. To use, place the following code just about anywhere. Be sure to leave a space between the icon and text for proper padding.
Icon classes cannot be directly combined with other components. They should not be used along with other classes on the same element. Instead, add a nested <span> and apply the icon classes to the <span>.
Use them in buttons, button groups for a toolbar, navigation, or prepended form inputs.
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.
By default, a dropdown menu is automatically positioned 100% from the top and along the left side of its parent. Add .dropdown-menu-right to a .dropdown-menu to right align the dropdown menu.
Dropdowns are automatically positioned via CSS within the normal flow of the document. This means dropdowns may be cropped by parents with certain overflow properties or appear out of bounds of the viewport. Address these issues on your own as they arise.
.pull-right alignmentAs of v3.1, we've deprecated .pull-right on dropdown menus. To right-align a menu, use .dropdown-menu-right. Right-aligned nav components in the navbar use a mixin version of this class to automatically align the menu. To override it, use .dropdown-menu-left.
Add a header to label sections of actions in any dropdown menu.
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. Split button dropdowns are not supported here.
Make a group of buttons stretch at equal sizes to span the entire width of its parent. Also works with button dropdowns within the button group.
Due to the specific HTML and CSS used to justify buttons (namely display: table-cell), the borders between them are doubled. In regular button groups, margin-left: -1px is used to stack the borders instead of removing them. However, margin doesn't work with display: table-cell. As a result, depending on your customizations to Bootstrap, you may wish to remove or re-color the borders.
<a> elementsJust wrap a series of .btns in .btn-group.btn-group-justified.
<button> elementsTo use justified button groups with <button> elements, you must wrap each button in a button group. Most browsers don't properly apply our CSS for justification to <button> elements, but since we support button dropdowns, we can workaround that.
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 single .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).
Do not mix form groups or grid column classes directly with input groups. Instead, nest the input group inside of the form group or grid-related element.
Place one add-on or button on either side of an input. You may also place one on both sides of an input.
We do not support multiple add-ons on a single side.
We do not support multiple form-controls in a single input group.
{% highlight html %}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).
Do not mix form groups or grid column classes directly with input groups. Instead, nest the input group inside of the form group or grid-related element.
Add the relative form sizing classes to the .input-group itself and contents within will automatically resize—no 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.
For tabs with tabbable areas, you must use the tabs JavaScript plugin.
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 at screens wider than 768px with .nav-justified. On smaller screens, the nav links are stacked.
Safari exhibits a bug in which resizing your browser horizontally causes rendering errors in the justified nav that are cleared upon refreshing. This bug is also shown in the justified nav example.
For any nav component (tabs or pills), 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.
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.
If JavaScript is disabled and the viewport is narrow enough that the navbar collapses, it will be impossible to expand the navbar and view the content within the .navbar-collapse.
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.
Place form content within .navbar-form for proper vertical alignment and collapsed behavior in narrow viewports. Use the alignment options to decide where it resides within the navbar content.
As a heads up, .navbar-form shares much of its code with .form-inline via mixin. Some form controls, like input groups, may require fixed widths to be show up properly within a navbar.
There are some caveats regarding using form controls within fixed elements on mobile devices. See our browser support docs for details.
Screen readers will have trouble with your forms if you don't include a label for every input. For these inline navbar forms, you can hide the labels using the .sr-only class.
Add the .navbar-btn class to <button> elements not residing in a <form> to vertically center them in the navbar.
Like the standard button classes, .navbar-btn can be used on <a> and <input> elements. However, neither .navbar-btn nor the standard button classes should be used on <a> elements within .navbar-nav.
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 and include a .container or .container-fluid to center and pad navbar content.
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 and include a .container or .container-fluid to center and pad navbar content.
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 and include a .container or .container-fluid to center and pad navbar content.
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 navigations.
A lightweight, flexible component that can optionally extend the entire viewport to showcase key content on your site.
This is a simple hero unit, a simple jumbotron-style component for calling extra attention to featured content or information.
To make the jumbotron full width, and without rounded corners, place it outside all .containers and instead add a .container within.
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.
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 and one of the four contextual classes (e.g., .alert-success) for basic alert messages.
Alerts don't have default classes, only base and modifier classes. A default gray alert doesn't make too much sense, so you're required to specify a type via contextual class. Choose from success, info, warning, or danger.
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.
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.
Use contextual classes to style list items, default or linked. Also includes .active state.
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.
Add any non-bordered .table within a panel for a seamless design. If there is a .panel-body, we add an extra border to the top of the table for separation.
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.
