Glyphicons

Available glyphs

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.

How to use

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.

Don't mix with other components

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>.

{% highlight html %} {% endhighlight %}

Examples

Use them in buttons, button groups for a toolbar, navigation, or prepended form inputs.

{% highlight html %} {% endhighlight %}

Dropdowns

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.

{% highlight html %} {% endhighlight %}

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.

May require additional positioning

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.

Deprecated .pull-right alignment

As of v3.1.0, 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.

{% highlight html %} {% endhighlight %}

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.

{% highlight html %} {% endhighlight %}

Button groups

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.

Tooltips & popovers in button groups require special setting

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).

Basic example

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

{% highlight html %}
{% endhighlight %}

Button toolbar

Combine sets of <div class="btn-group"> into a <div class="btn-toolbar"> for more complex components.

{% highlight html %} {% endhighlight %}

Sizing

Instead of applying button sizing classes to every button in a group, just add .btn-group-* to the .btn-group.

{% highlight html %}
...
...
...
...
{% endhighlight %}

Nesting

Place a .btn-group within another .btn-group when you want dropdown menus mixed with a series of buttons.

{% highlight html %}
{% endhighlight %}

Vertical variation

Make a set of buttons appear vertically stacked rather than horizontally. Split button dropdowns are not supported here.

{% highlight html %}
...
{% endhighlight %}

Justified button groups

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.

Handling borders

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.

IE8 and borders

Internet Explorer 8 doesn't render borders in on buttons in a justified button group, whether it's on <a> or <button> elements. To get around that, wrap each button in another .btn-group.

See #12476 for more information.

With <a> elements

Just wrap a series of .btns in .btn-group.btn-group-justified.


{% highlight html %}
...
{% endhighlight %}

With <button> elements

To 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.

{% highlight html %}
{% endhighlight %}

Button dropdowns

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

Plugin dependency

Button dropdowns require the dropdown plugin to be included in your version of Bootstrap.

Single button dropdowns

Turn a button into a dropdown toggle with some basic markup changes.

{% highlight html %}
{% endhighlight %}

Split button dropdowns

Similarly, create split button dropdowns with the same markup changes, only with a separate button.

{% highlight html %}
{% endhighlight %}

Sizing

Button dropdowns work with buttons of all sizes.

{% highlight html %}
{% endhighlight %}

Dropup variation

Trigger dropdown menus above elements by adding .dropup to the parent.

{% highlight html %}
{% endhighlight %}

Input groups

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.

Cross-browser compatibility

Avoid using <select> elements here as they cannot be fully styled in WebKit browsers.

Tooltips & popovers in input groups require special setting

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).

Don't mix with other components

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.

Basic example

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.

@

.00

$ .00
{% highlight html %}
@

$ .00
{% endhighlight %}

Sizing

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.

Checkboxes and radio addons

Place any checkbox or radio option within an input group's addon instead of text.

{% highlight html %}
{% endhighlight %}

Button addons

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.

{% highlight html %}
{% endhighlight %}

Buttons with dropdowns

{% highlight html %}
{% endhighlight %}

Segmented buttons

{% highlight html %}
{% endhighlight %}

Navs

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.

{% highlight html %} {% endhighlight %}

Requires JavaScript tabs plugin

For tabs with tabbable areas, you must use the tabs JavaScript plugin.

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

{% highlight html %} {% endhighlight %}

Pills are also vertically stackable. Just add .nav-stacked.

{% highlight html %} {% endhighlight %}

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 and responsive justified navs

As of v7.0.1, 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.


{% highlight html %} {% endhighlight %}

For any nav component (tabs or pills), add .disabled for gray links and no hover effects.

Link functionality not impacted

This class will only change the <a>'s appearance, not its functionality. Use custom JavaScript to disable links here.

{% highlight html %} {% endhighlight %}

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

Navbar

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.

Overflowing content

Since Bootstrap doesn't know how much space the content in your navbar needs, you might run into issues with content wrapping into a second row. To resolve this, you can:

  1. Reduce the amount or width of navbar items.
  2. Hide certain navbar items at certain screen sizes using responsive utility classes.
  3. 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.

Requires JavaScript

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.

{% highlight html %} {% endhighlight %}

Plugin dependency

The responsive navbar requires the collapse plugin to be included in your version of Bootstrap.

Make navbars accessible

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.

{% highlight html %} {% endhighlight %}

Mobile device caveats

There are some caveats regarding using form controls within fixed elements on mobile devices. See our browser support docs for details.

Always add labels

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.

{% highlight html %} {% endhighlight %}

Context-specific usage

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.

{% highlight html %} {% endhighlight %}

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.

{% highlight html %} {% endhighlight %}

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.

Right aligning multiple components

Navbars currently have a limitation with multiple .navbar-right classes. To properly space content, we use negative margin on the last .navbar-right element. When there are multiple elements using that class, these margins don't work as intended.

We'll revisit this when we can rewrite that component in v4.

Add .navbar-fixed-top and include a .container or .container-fluid to center and pad navbar content.

{% highlight html %} {% endhighlight %}

Body padding required

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.

{% highlight scss %} body { padding-top: 70px; } {% endhighlight %}

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.

{% highlight html %} {% endhighlight %}

Body padding required

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.

{% highlight scss %} body { padding-bottom: 70px; } {% endhighlight %}

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.

{% highlight html %} {% endhighlight %}

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

{% highlight html %} {% endhighlight %}

Breadcrumbs

Indicate the current page's location within a navigational hierarchy.

Separators are automatically added in CSS through :before and content.

{% highlight html %} {% endhighlight %}

Pagination

Provide pagination links for your site or app with the multi-page pagination component, or the simpler pager alternative.

Default pagination

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 %}

Disabled and active states

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

{% highlight html %} {% endhighlight %}

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

{% highlight html %} {% endhighlight %}

Sizing

Fancy larger or smaller pagination? Add .pagination-lg or .pagination-sm for additional sizes.

{% highlight html %} {% endhighlight %}

Pager

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

Default example

By default, the pager centers links.

{% highlight html %} {% endhighlight %}

Aligned links

Alternatively, you can align each link to the sides:

{% highlight html %} {% endhighlight %}

Optional disabled state

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

{% highlight html %} {% endhighlight %}

Labels

Available variations

Add any of the below mentioned modifier classes to change the appearance of a label.

Default Primary Success Info Warning Danger
{% highlight html %} Default Primary Success Info Warning Danger {% endhighlight %}

Badges

Easily highlight new or unread items by adding a <span class="badge"> to links, Bootstrap navs, and more.

Inbox 42
{% highlight html %} Inbox 42 {% endhighlight %}

Self collapsing

When there are no new or unread items, badges will simply collapse (via CSS's :empty selector) provided no content exists within.

Cross-browser compatibility

Badges won't self collapse in Internet Explorer 8 because it lacks support for the :empty selector.

Adapts to active nav states

Built-in styles are included for placing badges in active states in pill navigations.

Page header

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).

{% highlight html %} {% endhighlight %}

Thumbnails

Extend Bootstrap's grid system with the thumbnail component to easily display grids of images, videos, text, and more.

Default example

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

{% highlight html %}
...
{% endhighlight %}

Custom content

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

Alerts

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.

Examples

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.

No default class

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.

Well done! You successfully read this important alert message.
Heads up! This alert needs your attention, but it's not super important.
Warning! Better check yourself, you're not looking too good.
Oh snap! Change a few things up and try submitting again.
{% highlight html %}
...
...
...

{% endhighlight %}

Dismissable alerts

Build on any alert by adding an optional .alert-dismissable and close button.

Warning! Better check yourself, you're not looking too good.
{% highlight html %}
Warning! Better check yourself, you're not looking too good.
{% endhighlight %}

Ensure proper behavior across all devices

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.

Progress bars

Provide up-to-date feedback on the progress of a workflow or action with simple yet flexible progress bars.

Cross-browser compatibility

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.

Basic example

Default progress bar.

60% Complete
{% highlight html %}
60% Complete
{% endhighlight %}

With label

Remove the .sr-only class from within the progress bar to show a visible percentage. For low percentages, consider adding a min-width to ensure the label's text is fully visible.

60%
{% highlight html %}
60%
{% endhighlight %}

Low percentages

Progress bars representing low single digit percentages, as well as 0%, include a min-width: 20px; for legibility.

0%

Media object

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.

Default media

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

Generic placeholder image

Media list

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

{% highlight html %} {% endhighlight %}

List group

List groups are a flexible and powerful component for displaying not only simple lists of elements, but complex ones with custom content.

Basic example

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.

{% highlight html %} {% endhighlight %}

Badges

Add the badges component to any list group item and it will automatically be positioned on the right.

{% highlight html %} {% endhighlight %}

Linked items

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.

{% highlight html %}
Cras justo odio Dapibus ac facilisis in Morbi leo risus Porta ac consectetur ac Vestibulum at eros
{% endhighlight %}

Disabled items

Add .disabled to a .list-group-item to gray it out to appear disabled.

{% highlight html %}
Cras justo odio Dapibus ac facilisis in Morbi leo risus Porta ac consectetur ac Vestibulum at eros
{% endhighlight %}

Contextual classes

Use contextual classes to style list items, default or linked. Also includes .active state.

  • Dapibus ac facilisis in
  • Cras sit amet nibh libero
  • Porta ac consectetur ac
  • Vestibulum at eros
{% highlight html %}
Dapibus ac facilisis in Cras sit amet nibh libero Porta ac consectetur ac Vestibulum at eros
{% endhighlight %}

Custom content

Add nearly any HTML within, even for linked list groups like the one below.

{% highlight html %}

List group item heading

{% endhighlight %}

Panels

While not always necessary, sometimes you need to put your DOM in a box. For those situations, try the panel component.

Basic example

By default, all the .panel does is apply some basic border and padding to contain some content.

With tables

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.

Panel heading

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.

Responsive embed

Allow browsers to determine video or slideshow dimensions based on the width of their containing block by creating an intrinsic ratio that will properly scale on any device.

Rules are directly apply to <iframe>, <embed> and <object> elements, optionally use of an explicit descendant class .embed-responsive-item when you want to match the styling for other attributes.

Pro-Tip! You don't need to include frameborder="0" in your <iframe>s as we override that for you.
