Welcome to the Bootstrap documentation, the living, interactive style and code guide for all things Bootstrap. If you're new here, continue reading to learn how to get started. Otherwise, carry on you beautiful person you.
There are a few easy ways to quickly get started with Bootstrap, each one appealing to a different skill level and use case. Read through to see what suits your particular needs.
The fastest way to get started: get the compiled and minified versions of our CSS, JavaScript, and fonts. No documentation or original source files are included.
Get the original files for all CSS and JavaScript, along with a local copy of the docs by downloading the latest version directly from GitHub.
Clone the entire project or fork your own version of Bootstrap to make it your own by visiting us on GitHub.
Install and manage the original files for all CSS and JavaScript, along with a local copy of the docs, using Bower.
bower install bootstrap
Within the download you'll find the following directories and files, logically grouping common assets and providing both compiled and minified variations.
Once downloaded, unzip the compressed folder to see the structure of (the compiled) Bootstrap. You'll see something like this:
bootstrap/ ├── css/ │ ├── bootstrap.css │ ├── bootstrap.min.css ├── js/ │ ├── bootstrap.js │ ├── bootstrap.min.js └── fonts/ ├── glyphiconshalflings-regular.eot ├── glyphiconshalflings-regular.otf ├── glyphiconshalflings-regular.svg ├── glyphiconshalflings-regular.ttf └── glyphiconshalflings-regular.woff
This is the most basic form of Bootstrap: compiled files for quick drop-in usage in nearly any web project. We provide compiled CSS and JS (bootstrap.*
), as well as compiled and minified CSS and JS (bootstrap.min.*
). The image files are compressed using ImageOptim, a Mac app for compressing PNGs.
Please note that all JavaScript plugins require jQuery to be included.
Make use of a super basic HTML template, or dive into a few examples we've started for you. We encourage folks to iterate on these examples and not simply use them as an end result.
Copy and paste the HTML from below to get started with a bare bones Bootstrap document.
<!DOCTYPE html> <html> <head> <title>Bootstrap 101 Template</title> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <!-- Bootstrap --> <link href="css/bootstrap.min.css" rel="stylesheet" media="screen"> </head> <body> <h1>Hello, world!</h1> <!-- JavaScript plugins (requires jQuery) --> <script src="http://code.jquery.com/jquery.js"></script> <!-- Include all compiled plugins (below), or include individual files as needed --> <script src="js/bootstrap.min.js"></script> <!-- Optionally enable responsive features in IE8 --> <script src="js/respond.js"></script> </body> </html>
Fundamental HTML elements styled and enhanced with extensible classes.
Get the lowdown on the key pieces of Bootstrap's infrastructure, including our approach to better, faster, stronger web development.
Bootstrap makes use of certain HTML elements and CSS properties that require the use of the HTML5 doctype. Include it at the beginning of all your projects.
<!DOCTYPE html> <html lang="en"> ... </html>
With Bootstrap 2, we added optional mobile friendly styles for key aspects of the framework. With Bootstrap 3, we've rewritten the project to be mobile friendly from the start. Instead of adding on optional mobile styles, they're baked right into the core. In fact, Bootstrap is mobile first. Mobile first styles can be found throughout the entire library instead of in separate files.
To ensure proper rendering and touch zooming, add the viewport meta tag to your <head>
.
<meta name="viewport" content="width=device-width, initial-scale=1.0">
Bootstrap sets basic global display, typography, and link styles. Specifically, we:
margin
on the bodybackground-color: white;
on the body
@font-family-base
, @font-size-base
, and @line-height-base
attributes as our typographic base@link-color
and apply link underlines only on :hover
These styles can be found within scaffolding.less.
For improved cross-browser rendering, we use Normalize, a project by Nicolas Gallagher and Jonathan Neal.
Bootstrap includes a responsive, percent-based grid system that appropriately scales up to 12 columns as the device or viewport size increases—in other words, it's mobile first. It includes predefined classes for this, as well as powerful mixins for generating semantic layouts.
On mobile devices, the grid starts out stacked. Above 768px, it becomes horizontal as media queries kick in to apply float
s and width
s. To create a basic grid layout, wrap a series of .col-span-*
elements within a .row
. As this is a 12-column grid, each .span*
col-span-s a number of those 12 columns, and should always add up to 12 for each row (or the number of columns in the parent), even at mobile resolutions.
<div class="row"> <div class="col-span-1">1</div> <div class="col-span-1">1</div> <div class="col-span-1">1</div> <div class="col-span-1">1</div> <div class="col-span-1">1</div> <div class="col-span-1">1</div> <div class="col-span-1">1</div> <div class="col-span-1">1</div> <div class="col-span-1">1</div> <div class="col-span-1">1</div> <div class="col-span-1">1</div> <div class="col-span-1">1</div> </div> <div class="row"> <div class="col-span-4">4</div> <div class="col-span-4">4</div> <div class="col-span-4">4</div> </div> <div class="row"> <div class="col-span-6">6</div> <div class="col-span-6">6</div> </div>
Move columns to the right using .col-offset-*
classes. Each class increases the left margin of a column by a whole column. For example, .col-offset-4
moves .col-span-4
over four columns.
<div class="row"> <div class="col-span-4">...</div> <div class="col-span-4 col-offset-4">...</div> </div>
To nest your content with the default grid, add a new .row
and set of .span*
columns within an existing .span*
column. Nested rows should include a set of columns that add up to 12.
<div class="row"> <div class="col-span-9"> Level 1: 9 columns <div class="row"> <div class="col-span-6"> Level 2: 6 columns </div> <div class="col-span-6"> Level 2: 6 columns </div> </div> </div> </div>
Easily change the order of our built-in grid columns with .push*
and .pull*
modifier classes.
<div class="row show-grid"> <div class="col-span-9 col-push-3">9</div> <div class="col-span-3 col-pull-9">3</div> </div>
In addition to prebuilt grid classes for fast layouts, Bootstrap includes LESS variables and mixins for quickly generating your own simple, semantic layouts.
Variables determine the number of columns, the gutter width, and the media query point at which to begin floating columns. We use these to generate the predefined grid classes documented above, as well as for the custom mixins listed below.
@grid-columns: 12; @grid-gutter-width: 30px; @grid-float-breakpoint: 768px;
Mixins are used in conjunction with the grid variables to generate semantic CSS for individual grid columns.
// Creates a wrapper for a series of columns .make-row() { // Negative margin the row out to align the content of columns margin-left: (@grid-gutter-width / -2); margin-right: (@grid-gutter-width / -2); // Then clear the floated columns .clear_float(); } // Generate the columns .make-column(@columns) { @media (min-width: @grid-float-breakpoint) { float: left; // Calculate width based on number of columns available width: percentage(@columns / @grid-columns); } // Prevent columns from collapsing when empty min-height: 1px; // Set inner padding as gutters instead of margin padding-left: (@grid-gutter-width / 2); padding-right: (@grid-gutter-width / 2); } // Generate the column offsets .make-column-offset(@columns) { @media (min-width: @grid-float-breakpoint) { margin-left: percentage((@columns / @grid-columns)); } }
You can modify the variables to your own custom values, or just use the mixins with their default values. Here's an example of using the default settings to create a two-column layout with a gap between.
.wrapper { .make-row(); } .content-main { .make-column(8); } .content-secondary { .make-column(3); .make-column-offset(1); }
<div class="wrapper"> <div class="content-main">...</div> <div class="content-secondary">...</div> </div>

Bootstrap's global default font-size
is 14px, with a line-height
of 20px. This is applied to the <body>
and all paragraphs. In addition, <p>
(paragraphs) receive a bottom margin of half their line-height (10px by default).
Nullam quis risus eget urna mollis ornare vel eu leo. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Nullam id dolor id nibh ultricies vehicula.
Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Donec ullamcorper nulla non metus auctor fringilla. Duis mollis, est non commodo luctus, nisi erat porttitor ligula, eget lacinia odio sem nec elit. Donec ullamcorper nulla non metus auctor fringilla.
Maecenas sed diam eget risus varius blandit sit amet non magna. Donec id elit non mi porta gravida at eget metus. Duis mollis, est non commodo luctus, nisi erat porttitor ligula, eget lacinia odio sem nec elit.
<p>...</p>
Make a paragraph stand out by adding .lead
.
Vivamus sagittis lacus vel augue laoreet rutrum faucibus dolor auctor. Duis mollis, est non commodo luctus.
<p class="lead">...</p>
The typographic scale is based on two LESS variables in variables.less: @font-size-base
and @line-height-base
. The first is the base font-size used throughout and the second is the base line-height. We use those variables and some simple math to create the margins, paddings, and line-heights of all our type and more. Customize them and Bootstrap adapts.
Make use of HTML's default emphasis tags with lightweight styles.
For de-emphasizing inline or blocks of text, use the small tag to set text at 85% the size of the parent. Heading elements receive their own font-size
for nested <small>
elements.
This line of text is meant to be treated as fine print.
<small>This line of text is meant to be treated as fine print.</small>
For emphasizing a snippet of text with a heavier font-weight.
The following snippet of text is rendered as bold text.
<strong>rendered as bold text</strong>
For emphasizing a snippet of text with italics.
The following snippet of text is rendered as italicized text.
<em>rendered as italicized text</em>
Feel free to use <b>
and <i>
in HTML5. <b>
is meant to highlight words or phrases without conveying additional importance while <i>
is mostly for voice, technical terms, etc.
Easily realign text to components with text alignment classes.
Left aligned text.
Center aligned text.
Right aligned text.
<p class="text-left">Left aligned text.</p> <p class="text-center">Center aligned text.</p> <p class="text-right">Right aligned text.</p>
Convey meaning through color with a handful of emphasis utility classes.
Fusce dapibus, tellus ac cursus commodo, tortor mauris nibh.
Etiam porta sem malesuada magna mollis euismod.
Donec ullamcorper nulla non metus auctor fringilla.
Duis mollis, est non commodo luctus, nisi erat porttitor ligula.
<p class="muted">...</p> <p class="text-warning">...</p> <p class="text-error">...</p> <p class="text-success">...</p>
Stylized implementation of HTML's <abbr>
element for abbreviations and acronyms to show the expanded version on hover. Abbreviations with a title
attribute have a light dotted bottom border and a help cursor on hover, providing additional context on hover.
For expanded text on long hover of an abbreviation, include the title
attribute with the <abbr>
element.
An abbreviation of the word attribute is attr.
<abbr title="attribute">attr</abbr>
Add .initialism
to an abbreviation for a slightly smaller font-size.
HTML is the best thing since sliced bread.
<abbr title="HyperText Markup Language" class="initialism">HTML</abbr>
Present contact information for the nearest ancestor or the entire body of work. Preserve formatting by ending all lines with <br>
.
<address> <strong>Twitter, Inc.</strong><br> 795 Folsom Ave, Suite 600<br> San Francisco, CA 94107<br> <abbr title="Phone">P:</abbr> (123) 456-7890 </address> <address> <strong>Full Name</strong><br> <a href="mailto:#">first.last@example.com</a> </address>
For quoting blocks of content from another source within your document.
Wrap <blockquote>
around any HTML as the quote. For straight quotes we recommend a <p>
.
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.
<blockquote> <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p> </blockquote>
Style and content changes for simple variations on a standard blockquote.
Add <small>
tag for identifying the source. Wrap the name of the source work in <cite>
.
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.
Someone famous in Source Title
<blockquote> <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p> <small>Someone famous <cite title="Source Title">Source Title</cite></small> </blockquote>
Use .pull-right
for a floated, right-aligned blockquote.
<blockquote class="pull-right"> ... </blockquote>
A list of items in which the order does not explicitly matter.
<ul> <li>...</li> </ul>
A list of items in which the order does explicitly matter.
<ol> <li>...</li> </ol>
Remove the default list-style
and left margin on list items (immediate children only). This only applies to immediate children list items, meaning you will need to add the class for any nested lists as well.
<ul class="list-unstyled"> <li>...</li> </ul>
Place all list items on a single line with inline-block
and some light padding.
<ul class="list-inline"> <li>...</li> </ul>
A list of terms with their associated descriptions.
<dl> <dt>...</dt> <dd>...</dd> </dl>
Make terms and descriptions in <dl>
line up side-by-side.
<dl class="dl-horizontal"> <dt>...</dt> <dd>...</dd> </dl>
Horizontal description lists will truncate terms that are too long to fit in the left column fix text-overflow
. In narrower viewports, they will change to the default stacked layout.
Wrap inline snippets of code with <code>
.
<section>
should be wrapped as inline.
For example, <section>
should be wrapped as inline.
Use <pre>
for multiple lines of code. Be sure to escape any angle brackets in the code for proper rendering.
<p>Sample text here...</p>
<pre><p>Sample text here...</p></pre>
You may optionally add the .pre-scrollable
class which will set a max-height of 350px and provide a y-axis scrollbar.
For basic styling—light padding and only horizontal dividers—add the base class .table
to any <table>
. It may seem super redundant, but given the widespread use of tables for other plugins like calendars and date pickers, we've opted to isolate our custom table styles.
# | First Name | Last Name | Username |
---|---|---|---|
1 | Mark | Otto | @mdo |
2 | Jacob | Thornton | @fat |
3 | Larry | the Bird |
<table class="table"> ... </table>
Add any of the following classes to the .table
base class.
Use .table-striped
to add zebra-striping to any table row within the <tbody>
via the :nth-child
CSS selector (not available in IE8).
# | First Name | Last Name | Username |
---|---|---|---|
1 | Mark | Otto | @mdo |
2 | Jacob | Thornton | @fat |
3 | Larry | the Bird |
<table class="table table-striped"> ... </table>
Add .table-bordered
for borders and rounded corners.
# | First Name | Last Name | Username |
---|---|---|---|
1 | Mark | Otto | @mdo |
Mark | Otto | @TwBootstrap | |
2 | Jacob | Thornton | @fat |
3 | Larry the Bird |
<table class="table table-bordered"> ... </table>
Add .table-hover
to enable a hover state on table rows within a <tbody>
.
# | First Name | Last Name | Username |
---|---|---|---|
1 | Mark | Otto | @mdo |
2 | Jacob | Thornton | @fat |
3 | Larry the Bird |
<table class="table table-hover"> ... </table>
Add .table-condensed
to make tables more compact by cutting cell padding in half.
# | First Name | Last Name | Username |
---|---|---|---|
1 | Mark | Otto | @mdo |
2 | Jacob | Thornton | @fat |
3 | Larry the Bird |
<table class="table table-condensed"> ... </table>
Use contextual classes to color table rows.
Class | Description |
---|---|
.success
|
Indicates a successful or positive action. |
.error
|
Indicates a dangerous or potentially negative action. |
.warning
|
Indicates a warning that might need attention. |
.info

Used as an alternative to the default styles. |
# | Product | Payment Taken | Status |
---|---|---|---|
1 | TB - Monthly | 01/04/2012 | Approved |

... <tr class="success"> <td>1</td> <td>TB - Monthly</td> <td>01/04/2012</td> <td>Approved</td> </tr> ...
Individual form controls automatically receive some global styling. By default, inputs are set to width: 100%;
.
<form> <fieldset> <legend>Legend</legend> <label>Label name</label> <input type="text" placeholder="Type something…"> <p class="help-block">Example block-level help text here.</p> <div class="checkbox"> <label> <input type="checkbox"> Check me out </label> </div> <button type="submit" class="btn">Submit</button> </fieldset> </form>
Included with Bootstrap are optional form layouts for common use cases.
Add .form-inline
for left-aligned labels and inline-block controls for a compact layout.
<form class="form-inline"> <input type="text" class="col-span-3" placeholder="Email"> <input type="password" class="col-span-3" placeholder="Password"> <div class="checkbox"> <label> <input type="checkbox"> Remember me </label> </div> <button type="submit" class="btn">Sign in</button> </form>
Right align labels and float them to the left to make them appear on the same line as controls. Requires the most markup changes from a default form:
.form-horizontal
to the form.control-group
.control-label
to the label.controls
for proper alignment<form class="form-horizontal"> <div class="control-group"> <label class="control-label" for="inputEmail">Email</label> <div class="controls"> <input type="text" id="inputEmail" placeholder="Email"> </div> </div> <div class="control-group"> <label class="control-label" for="inputPassword">Password</label> <div class="controls"> <input type="password" id="inputPassword" placeholder="Password"> <div class="checkbox"> <label> <input type="checkbox"> Remember me </label> </div> </div> </div> <div class="control-group"> <div class="controls"> <button type="submit" class="btn">Sign in</button> </div> </div> </form>
Examples of standard form controls supported in an example form layout.
Most common form control, text-based input fields. Includes support for all HTML5 types: text, password, datetime, datetime-local, date, month, time, week, number, email, url, search, tel, and color.
Requires the use of a specified type
at all times.
<input type="text" placeholder="Text input">
Form control which supports multiple lines of text. Change rows
attribute as necessary.
<textarea rows="3"></textarea>
Checkboxes are for selecting one or several options in a list while radios are for selecting one option from many.
<div class="checkbox"> <label> <input type="checkbox" value=""> Option one is this and that—be sure to include why it's great </label> </div> <div class="radio"> <label> <input type="radio" name="optionsRadios" id="optionsRadios1" value="option1" checked> Option one is this and that—be sure to include why it's great </label> </div>
Use .checkbox-inline
or .radio-inline
class to a series of checkboxes or radios for controls appear on the same line.
<label class="checkbox-inline"> <input type="checkbox" id="inlineCheckbox1" value="option1"> 1 </label> <label class="checkbox-inline"> <input type="checkbox" id="inlineCheckbox2" value="option2"> 2 </label> <label class="checkbox-inline"> <input type="checkbox" id="inlineCheckbox3" value="option3"> 3 </label>
Use the default option or specify a multiple="multiple"
to show multiple options at once.
<select> <option>1</option> <option>2</option> <option>3</option> <option>4</option> <option>5</option> </select> <select multiple="multiple"> <option>1</option> <option>2</option> <option>3</option> <option>4</option> <option>5</option> </select>
Provide feedback to users or visitors with basic feedback states on form controls and labels.
We remove the default outline
styles on some form controls and apply a box-shadow
in its place for :focus
.
<input id="focusedInput" type="text" value="This is focused...">
Style inputs via default browser functionality with :invalid
. Specify a type
, add the required
attribute if the field is not optional, and (if applicable) specify a pattern
.
This is not available in versions of Internet Explorer 7-9 due to lack of support for CSS pseudo selectors.
<input class="col-span-3" type="email" placeholder="test@example.com" required>
Add the disabled
attribute on an input to prevent user input and trigger a slightly different look.
<input id="disabledInput" type="text" placeholder="Disabled input here..." disabled>
Add the disabled
attribute to a <fieldset>
to disable all the controls within the <fieldset>
at once. Link buttons (with the <a>
element) will be aesthetically disabled, but you will need custom JavaScript to disable their behavior.
<form class="form-inline"> <fieldset disabled> <div> <input type="text" class="col-span-4" placeholder="Disabled input"> </div> <div> <select class="col-span-4"> <option>Disabled select</option> </select> </div> <div class="checkbox"> <label> <input type="checkbox"> Can't check this </label> </div> <button type="submit" class="btn btn-primary">Submit</button> </fieldset> </form>
Bootstrap includes validation styles for error, warning, info, and success messages. To use:
.has-warning
, .has-error
, or .has-success
to the parent elementValidation styles are applied on a per-input basis. With horizontal forms, the <label class="control-label">
will always be styled.
<div class="control-group has-warning"> <label class="control-label" for="inputWarning">Input with warning</label> <div class="controls"> <input type="text" class="input-with-feedback" id="inputWarning"> </div> </div> <div class="control-group has-error"> <label class="control-label" for="inputError">Input with error</label> <div class="controls"> <input type="text" class="input-with-feedback" id="inputError"> </div> </div> <div class="control-group has-success"> <label class="control-label" for="inputSuccess">Input with success</label> <div class="controls"> <input type="text" class="input-with-feedback" id="inputSuccess"> </div> </div>
Adding on top of existing browser controls, Bootstrap includes other useful form components.
Add text or buttons before, after, or on both sides of any text-based input. Use .input-group
with a .add-on
to prepend or append elements to an <input>
.
Avoid using <select>
elements here as they cannot be fully styled in WebKit browsers.
<div class="input-group col-span-9"> <span class="input-group-addon">@</span> <input type="text" placeholder="Username"> </div> <div class="input-group col-span-6"> <input type="text"> <span class="input-group-addon">.00</span> </div> <div class="input-group col-span-3"> <span class="input-group-addon">$</span> <input type="text"> <span class="input-group-addon">.00</span> </div>
Add the relative form sizing classes to the `.input-group-addon`.
<div class="input-group col-span-9"> <span class="input-group-addon input-large">@</span> <input type="text" class="input-large" placeholder="Username"> </div> <div class="input-group col-span-9"> <span class="input-group-addon">@</span> <input type="text" placeholder="Username"> </div> <div class="input-group col-span-9"> <span class="input-group-addon input-small">@</span> <input type="text" class="input-small" placeholder="Username"> </div>
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.
<div class="input-group col-span-7"> <span class="input-group-btn"> <button class="btn" type="button">Go!</button> </span> <input type="text"> </div> <div class="input-group col-span-7"> <input type="text"> <span class="input-group-btn"> <button class="btn" type="button">Go!</button> </span> </div>
<div class="input-group col-span-7"> <div class="input-group-btn"> <button class="btn dropdown-toggle" data-toggle="dropdown">Action <span class="caret"></span></button> <ul class="dropdown-menu"> <li><a href="#">Action</a></li> <li><a href="#">Another action</a></li> <li><a href="#">Something else here</a></li> <li class="divider"></li> <li><a href="#">Separated link</a></li> </ul> </div><!-- /btn-group --> <input type="text"> </div><!-- /input-group --> <div class="input-group col-span-7"> <input type="text"> <div class="input-group-btn"> <button class="btn dropdown-toggle" data-toggle="dropdown">Action <span class="caret"></span></button> <ul class="dropdown-menu"> <li><a href="#">Action</a></li> <li><a href="#">Another action</a></li> <li><a href="#">Something else here</a></li> <li class="divider"></li> <li><a href="#">Separated link</a></li> </ul> </div><!-- /btn-group --> </div><!-- /input-group -->
<div class="input-group col-span-7"> <div class="input-group-btn"> <!-- Button and dropdown menu --> </div> <input type="text"> </div> <div class="input-group col-span-7"> <input type="text"> <div class="input-group-btn btn-group"> <!-- Button and dropdown menu --> </div> </div>
Use relative sizing classes like .input-large
or match your inputs to the grid column sizes using .span*
classes.
Create larger or smaller form controls that match button sizes.
<input class="input-large" type="text" placeholder=".input-large"> <input type="text" placeholder="Default input"> <input class="input-small" type="text" placeholder=".input-small">
Use .span1
to .span12
for setting widths on inputs that match Bootstrap's grid system.
<input class="col-span-1" type="text" placeholder=".col-span-1"> <input class="col-span-2" type="text" placeholder=".col-span-2"> <input class="col-span-3" type="text" placeholder=".col-span-3"> <select class="col-span-1"> ... </select> <select class="col-span-2"> ... </select> <select class="col-span-3"> ... </select>
If you need multiple inputs on the same line, wrap them in the standard grid markup (with .row
and .span*
classes). Each input should have it's own column and will expand to fill the available width automatically.
<div class="row"> <div class="col-span-4"> <input type="text" placeholder=".col-span-4"> </div> <div class="col-span-4"> <input type="text" placeholder=".col-span-4"> </div> <div class="col-span-4"> <input type="text" placeholder=".col-span-4"> </div> </div>
Present data in a form that's not editable without using actual form markup.
<span class="uneditable-input">Some value here</span>
End a form with a group of actions (buttons). When placed within a .form-horizontal
, the buttons will automatically indent to line up with the form controls.
<div class="form-actions"> <button type="submit" class="btn btn-primary">Save changes</button> <button type="button" class="btn">Cancel</button> </div>
Inline and block level support for help text that appears around form controls.
<input type="text"> <span class="help-inline">Inline help text</span>
<input type="text"> <span class="help-block">A longer block of help text that breaks onto a new line and may extend beyond one line.</span>
Button styles can be applied to anything with the .btn
class applied. However, typically you'll want to apply these to only <a>
and <button>
elements for the best rendering.
<!-- Standard gray button with gradient --> <button type="button" class="btn btn-default">Default</button> <!-- Provides extra visual weight and identifies the primary action in a set of buttons --> <button type="button" class="btn btn-primary">Primary</button> <!-- Indicates a successful or positive action --> <button type="button" class="btn btn-success">Success</button> <!-- Contextual button for informational alert messages --> <button type="button" class="btn btn-info">Info</button> <!-- Indicates caution should be taken with this action --> <button type="button" class="btn btn-warning">Warning</button> <!-- Indicates a dangerous or potentially negative action --> <button type="button" class="btn btn-danger">Danger</button> <!-- Deemphasize a button by making it look like a link while maintaining button behavior --> <button type="button" class="btn btn-link">Link</button>
IE9 doesn't crop background gradients on rounded corners, so we remove it. Related, IE9 jankifies disabled button
elements, rendering text gray with a nasty text-shadow that we cannot fix.
Fancy larger or smaller buttons? Add .btn-large
, .btn-small
, or .btn-mini
for additional sizes.
<p> <button type="button" class="btn btn-large btn-primary">Large button</button> <button type="button" class="btn btn-large">Large button</button> </p> <p> <button type="button" class="btn btn-primary">Default button</button> <button type="button" class="btn">Default button</button> </p> <p> <button type="button" class="btn btn-small btn-primary">Small button</button> <button type="button" class="btn btn-small">Small button</button> </p> <p> <button type="button" class="btn btn-mini btn-primary">Mini button</button> <button type="button" class="btn btn-mini">Mini button</button> </p>
Create block level buttons—those that col-span- the full width of a parent— by adding .btn-block
.
<button type="button" class="btn btn-large btn-block btn-primary">Block level button</button> <button type="button" class="btn btn-large btn-block">Block level button</button>
Make buttons look unclickable by fading them back 50%.
Add the disabled
attribute to <button>
buttons.
<button type="button" class="btn btn-large btn-primary disabled" disabled="disabled">Primary button</button> <button type="button" class="btn btn-large" disabled="disabled">Button</button>
Add the .disabled
class to <a>
buttons.
<a href="#" class="btn btn-large btn-primary disabled">Primary link</a> <a href="#" class="btn btn-large disabled">Link</a>
We use .disabled
as a utility class here, similar to the common .active
class, so no prefix is required. Also, this class is only for aesthetic; you must use custom JavaScript to disable links here.
Use the .btn
class on an <a>
, <button>
, or <input>
element.
<a class="btn" href="">Link</a> <button class="btn" type="submit">Button</button> <input class="btn" type="button" value="Input"> <input class="btn" type="submit" value="Submit">
As a best practice, we highly recommend matching using the <button<
element whenever possible to ensure matching cross-browser rendering.
Add classes to an <img>
element to easily style images in any project. Rounded corners are not available in IE8.
<img src="..." class="img-rounded"> <img src="..." class="img-circle"> <img src="..." class="img-thumbnail">
Use the generic close icon for dismissing content like modals and alerts.
<button class="close" style="float: none;">×</button>
Float an element left
<div class="pull-left">...</div>
.pull-left { float: left; }
Float an element right
<div class="pull-right">...</div>
.pull-right { float: right; }
Clear the float
on any element. Utilizes the micro clearfix as popularized by Nicolas Gallagher.
<div class="clearfix">...</div>
// Mixin .clearfix { &:before, &:after { content: " "; display: table; } &:after { clear: both; } } // Usage .element { .clearfix(); }
For faster mobile-friendly development, use these utility classes for showing and hiding content by device via media query. Also included are utility classes for toggling content when printed.
Class | Browser | |
---|---|---|
.visible-print |
Hidden | Visible |
.hidden-print |
Visible | Hidden |
Use on a limited basis and avoid creating entirely different versions of the same site. Instead, use them to complement each device's presentation. Responsive utilities should not be used with tables, and as such are not supported.
Resize your browser or load on different devices to test the above classes.
Green checkmarks indicate that class is visible in your current viewport.
Here, green checkmarks indicate that class is hidden in your current viewport.
Dozens of reusable components built to provide iconography, dropdowns, navigation, alerts, popovers, and much more.
Bootstrap comes with all 160 of Glyphicons Halflings set, all available in font formats for easy coloring, sizing, and placement.
Glyphicons Halflings are normally not available for free, but an arrangement between Bootstrap and the Glyphicons creator have made this possible at no cost to you as developers. As a thank you, we ask you to include an optional link back to Glyphicons whenever practical.
Add the appropriate class to any inline element. All icon classes are prefixed with glyphicon-
for easy styling. To use, place the following code just about anywhere:
<span class="glyphicon glyphicon-search"></span>
Want to change the icon color? Just change the color
of the parent element.
When using beside strings of text, as in buttons or nav links, be sure to leave a space after the icon for proper spacing.
Use them in buttons, button groups for a toolbar, navigation, or prepended form inputs.
<div class="btn-toolbar"> <div class="btn-group"> <a class="btn" href="#"><span class="glyphicon glyphicon-align-left"></span></a> <a class="btn" href="#"><span class="glyphicon glyphicon-align-center"></span></a> <a class="btn" href="#"><span class="glyphicon glyphicon-align-right"></span></a> <a class="btn" href="#"><span class="glyphicon glyphicon-align-justify"></span></a> </div> </div>
<div class="btn-group"> <a class="btn btn-primary" href="#"><span class="glyphicon glyphicon-user"></span> User</a> <a class="btn btn-primary dropdown-toggle" data-toggle="dropdown" href="#"><span class="caret"></span></a> <ul class="dropdown-menu"> <li><a href="#"><span class="glyphicon glyphicon-pencil"></span> Edit</a></li> <li><a href="#"><span class="glyphicon glyphicon-trash"></span> Delete</a></li> <li><a href="#"><span class="glyphicon glyphicon-ban-circle"></span> Ban</a></li> <li class="divider"></li> <li><a href="#"><span class="glyphicon glyphicon-"></span> Make admin</a></li> </ul> </div>
<a class="btn btn-large" href="#"><span class="glyphicon glyphicon-star"></span> Star</a>
<a class="btn btn-small" href="#"><span class="glyphicon glyphicon-star"></span></a>
<ul class="nav nav-list"> <li class="active"><a href="#"><span class="glyphicon glyphicon-home"></span> Home</a></li> <li><a href="#"><span class="glyphicon glyphicon-book"></span> Library</a></li> <li><a href="#"><span class="glyphicon glyphicon-pencil"></span> Applications</a></li> <li><a href="#"><span class="glyphicon glyphicon-"></span> Misc</a></li> </ul>
<div class="control-group"> <label class="control-label" for="inputIcon">Email address</label> <div class="controls"> <div class="input-group"> <span class="input-group-addon"><span class="glyphicon glyphicon-envelope"></span></span> <input class="span2" id="inputIcon" type="text"> </div> </div> </div>
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.
<div class="dropdown"> <!-- Link or button to toggle dropdown --> <ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu"> <li><a tabindex="-1" href="#">Action</a></li> <li><a tabindex="-1" href="#">Another action</a></li> <li><a tabindex="-1" href="#">Something else here</a></li> <li class="divider"></li> <li><a tabindex="-1" href="#">Separated link</a></li> </ul> </div>
Add .pull-right
to a .dropdown-menu
to right align the dropdown menu.
<ul class="dropdown-menu pull-right" role="menu" aria-labelledby="dLabel"> ... </ul>
Add .disabled
to a <li>
in the dropdown to disable the link.
<ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu"> <li><a tabindex="-1" href="#">Regular link</a></li> <li class="disabled"><a tabindex="-1" href="#">Disabled link</a></li> <li><a tabindex="-1" href="#">Another link</a></li> </ul>
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.
<ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu"> ... <li class="dropdown-submenu pull-left"> <a tabindex="-1" href="#">More options</a> <ul class="dropdown-menu"> <li><a tabindex="-1" href="#">Second level link</a></li> <li><a tabindex="-1" href="#">Second level link</a></li> <li><a tabindex="-1" href="#">Second level link</a></li> <li><a tabindex="-1" href="#">Second level link</a></li> <li><a tabindex="-1" href="#">Second level link</a></li> </ul> </li> ... </ul>
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.
Wrap a series of buttons with .btn
in .btn-group
.
<div class="btn-group"> <button type="button" class="btn">Left</button> <button type="button" class="btn">Middle</button> <button type="button" class="btn">Right</button> </div>
Combine sets of <div class="btn-group">
into a <div class="btn-toolbar">
for more complex components.
<div class="btn-toolbar"> <div class="btn-group">...</div> <div class="btn-group">...</div> <div class="btn-group">...</div> </div>
Make a set of buttons appear vertically stacked rather than horizontally.
<div class="btn-group btn-group-vertical"> ... </div>
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.
<div class="btn-group btn-group-justified"> ... </div>
Use any button to trigger a dropdown menu by placing it within a .btn-group
and providing the proper menu markup. Requires the Bootstrap dropdown plugin.
Turn a button into dropdown toggle, or add a second button to toggle the dropdown while retaining the primary button action.
<!-- Single button --> <div class="btn-group"> <button class="btn dropdown-toggle" data-toggle="dropdown"> Action <span class="caret"></span> </button> <ul class="dropdown-menu"> <li><a href="#">Action</a></li> <li><a href="#">Another action</a></li> <li><a href="#">Something else here</a></li> <li class="divider"></li> <li><a href="#">Separated link</a></li> </ul> </div> <!-- Split button --> <div class="btn-group"> <button class="btn">Action</button> <button class="btn dropdown-toggle" data-toggle="dropdown"> <span class="caret"></span> </button> <ul class="dropdown-menu"> <li><a href="#">Action</a></li> <li><a href="#">Another action</a></li> <li><a href="#">Something else here</a></li> <li class="divider"></li> <li><a href="#">Separated link</a></li> </ul> </div>
Button dropdowns work at any size: .btn-large
, .btn-small
, or .btn-mini
.
<!-- Large button group --> <div class="btn-group"> <button class="btn btn-large dropdown-toggle" type="button" data-toggle="dropdown"> Large button <span class="caret"></span> </button> <ul class="dropdown-menu"> ... </ul> </div> <!-- Small button group --> <div class="btn-group"> <button class="btn btn-small dropdown-toggle" type="button" data-toggle="dropdown"> Small button <span class="caret"></span> </button> <ul class="dropdown-menu"> ... </ul> </div> <!-- Mini button group --> <div class="btn-group"> <button class="btn btn-mini dropdown-toggle" type="button" data-toggle="dropdown"> Mini button <span class="caret"></span> </button> <ul class="dropdown-menu"> ... </ul> </div>
Trigger dropdown menus above elements by adding .dropup
to the parent.
<div class="btn-group dropup"> <button class="btn">Dropup</button> <button class="btn dropdown-toggle" data-toggle="dropdown"> <span class="caret"></span> </button> <ul class="dropdown-menu"> <!-- Dropdown menu links --> </ul> </div>
