Typography
Headings
All HTML headings, <h1>
through <h6>
, are available. .h1
through .h6
classes are also available, for when you want to match the font styling of a heading but still want your text to be displayed inline.

Body copy
Bootstrap's global default font-size
is 14px, with a line-height
of 1.428. This is applied to the <body>
and all paragraphs. In addition, <p>
(paragraphs) receive a bottom margin of half their computed 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>
Lead body copy
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>
Emphasis
Make use of HTML's default emphasis tags with lightweight styles.
Small text
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.
You may alternatively use an inline element with .small
in place of any <small>
.
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>
Bold
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>
Italics
For emphasizing a snippet of text with italics.
The following snippet of text is rendered as italicized text.
<em>rendered as italicized text</em>
Alternate elements
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.
Alignment classes
Easily realign text to components with text alignment classes.
Left aligned text.
Center aligned text.
Right aligned text.
Justified 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>
<p class="text-justify">Justified text.</p>
Abbreviations
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.
Basic abbreviation
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>
Initialism
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>
Addresses
Present contact information for the nearest ancestor or the entire body of work. Preserve formatting by ending all lines with <br>
.

Blockquotes
For quoting blocks of content from another source within your document.
Default blockquote
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>
Blockquote options
Style and content changes for simple variations on a standard <blockquote>
.
Naming a source
Add a <footer>
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.
<blockquote>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
<footer>Someone famous in <cite title="Source Title">Source Title</cite></footer>
</blockquote>
Alternate displays
Add .blockquote-reverse
for a blockquote with right-aligned content.
<blockquote class="blockquote-reverse">
...
</blockquote>
Lists
Unordered
A list of items in which the order does not explicitly matter.
- Lorem ipsum dolor sit amet
- Consectetur adipiscing elit
- Integer molestie lorem at massa
- Facilisis in pretium nisl aliquet
- Nulla volutpat aliquam velit
- Phasellus iaculis neque
- Purus sodales ultricies
- Vestibulum laoreet porttitor sem

- Nulla volutpat aliquam velit
- Faucibus porta lacus fringilla vel
- Aenean sit amet erat nunc
- Eget porttitor lorem
<ol>
<li>...</li>
</ol>
Unstyled
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.
- Lorem ipsum dolor sit amet
- Consectetur adipiscing elit
- Integer molestie lorem at massa
- Facilisis in pretium nisl aliquet
- Nulla volutpat aliquam velit
- Phasellus iaculis neque
- Purus sodales ultricies
- Vestibulum laoreet porttitor sem
- Ac tristique libero volutpat at
- Faucibus porta lacus fringilla vel
- Aenean sit amet erat nunc
- Eget porttitor lorem
<ul class="list-unstyled">
<li>...</li>
</ul>
Inline
Place all list items on a single line with display: inline-block;
and some light padding.
- Lorem ipsum
- Phasellus iaculis
- Nulla volutpat
<ul class="list-inline">
<li>...</li>
</ul>
Description
A list of terms with their associated descriptions.
- Description lists
- A description list is perfect for defining terms.
- Euismod
- Vestibulum id ligula porta felis euismod semper eget lacinia odio sem nec elit.
- Donec id elit non mi porta gravida at eget metus.
- Malesuada porta
- Etiam porta sem malesuada magna mollis euismod.
<dl>
<dt>...</dt>
<dd>...</dd>
</dl>
Horizontal description
Make terms and descriptions in <dl>
line up side-by-side. Starts off stacked like default <dl>
s, but when the navbar expands, so do these.
- Description lists
- A description list is perfect for defining terms.
- Euismod
- Vestibulum id ligula porta felis euismod semper eget lacinia odio sem nec elit.
- Donec id elit non mi porta gravida at eget metus.
- Malesuada porta
- Etiam porta sem malesuada magna mollis euismod.
- Felis euismod semper eget lacinia
- Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus.
<dl class="dl-horizontal">
<dt>...</dt>
<dd>...</dd>
</dl>
Auto-truncating
Horizontal description lists will truncate terms that are too long to fit in the left column with text-overflow
. In narrower viewports, they will change to the default stacked layout.
Code
Inline
Wrap inline snippets of code with <code>
.
<section>
should be wrapped as inline.
For example, <code><section></code> should be wrapped as inline.
User input
Use the <kbd>
to indicate input that is typically entered via keyboard.
To switch directories, type <kbd>cd</kbd> followed by the name of the directory.
Basic block
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.
Tables
Basic example
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>
Striped rows
Use .table-striped
to add zebra-striping to any table row within the <tbody>
.
Cross-browser compatibility
Striped tables are styled via the :nth-child
CSS selector, which is not available in Internet Explorer 8.
# | First Name | Last Name | Username |
---|---|---|---|
1 | Mark | Otto | @mdo |
2 | Jacob | Thornton | @fat |
3 | Larry | the Bird |
<table class="table table-striped">
...
</table>
Bordered table
Add .table-bordered
for borders on all sides of the table and cells.
# | 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>
Hover rows
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>
Condensed 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>
Contextual classes
Use contextual classes to color table rows or individual cells.
Class | Description |
---|---|
.active
|
Applies the hover color to a particular row or cell |
.success
|
Indicates a successful or positive action |
.info
|
Indicates a neutral informative change or action |
.warning
|
Indicates a warning that might need attention |
.danger
|
Indicates a dangerous or potentially negative action |
# | Column heading | Column heading | Column heading |
---|---|---|---|
1 | Column content | Column content | Column content |
2 | Column content | Column content | Column content |
3 | Column content | Column content | Column content |
4 | Column content | Column content | Column content |
5 | Column content | Column content | Column content |
6 | Column content | Column content | Column content |
7 | Column content | Column content | Column content |
8 | Column content | Column content | Column content |
9 | Column content | Column content | Column content |
<!-- On rows -->
<tr class="active">...</tr>
<tr class="success">...</tr>
<tr class="warning">...</tr>
<tr class="danger">...</tr>
<tr class="info">...</tr>
<!-- On cells (`td` or `th`) -->
<tr>
<td class="active">...</td>
<td class="success">...</td>
<td class="warning">...</td>
<td class="danger">...</td>
<td class="info">...</td>
</tr>
Responsive tables
Create responsive tables by wrapping any .table
in .table-responsive
to make them scroll horizontally up to small devices (under 768px). When viewing on anything larger than 768px wide, you will not see any difference in these tables.
# | Table heading | Table heading | Table heading | Table heading | Table heading | Table heading |
---|---|---|---|---|---|---|
1 | Table cell | Table cell | Table cell | Table cell | Table cell | Table cell |
2 | Table cell | Table cell | Table cell | Table cell | Table cell | Table cell |
3 | Table cell | Table cell | Table cell | Table cell | Table cell | Table cell |

3 | Table cell | Table cell | Table cell | Table cell | Table cell | Table cell |
<div class="table-responsive">
<table class="table">
...
</table>
</div>
Forms
Basic example
Individual form controls automatically receive some global styling. All textual <input>
, <textarea>
, and <select>
elements with .form-control
are set to width: 100%;
by default. Wrap labels and controls in .form-group
for optimum spacing.
<form role="form">
<div class="form-group">
<label for="exampleInputEmail1">Email address</label>
<input type="email" class="form-control" id="exampleInputEmail1" placeholder="Enter email">
</div>
<div class="form-group">
<label for="exampleInputPassword1">Password</label>
<input type="password" class="form-control" id="exampleInputPassword1" placeholder="Password">
</div>
<div class="form-group">
<label for="exampleInputFile">File input</label>
<input type="file" id="exampleInputFile">
<p class="help-block">Example block-level help text here.</p>
</div>
<div class="checkbox">
<label>
<input type="checkbox"> Check me out
</label>
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>
Don't mix form groups with input groups
Do not mix form groups directly with input groups. Instead, nest the input group inside of the form group.
Inline form
Add .form-inline
to your <form>
for left-aligned and inline-block controls. This only applies to forms within viewports that are at least 768px wide.
Requires custom widths
Inputs, selects, and textareas are 100% wide by default in Bootstrap. To use the inline form, you'll have to set a width on the form controls used within.
Always add labels
Screen readers will have trouble with your forms if you don't include a label for every input. For these inline forms, you can hide the labels using the .sr-only
class.
<form class="form-inline" role="form">
<div class="form-group">
<label class="sr-only" for="exampleInputEmail2">Email address</label>
<input type="email" class="form-control" id="exampleInputEmail2" placeholder="Enter email">
</div>
<div class="form-group">
<label class="sr-only" for="exampleInputPassword2">Password</label>
<input type="password" class="form-control" id="exampleInputPassword2" placeholder="Password">
</div>
<div class="checkbox">
<label>
<input type="checkbox"> Remember me
</label>
</div>
<button type="submit" class="btn btn-default">Sign in</button>
</form>
Horizontal form
Use Bootstrap's predefined grid classes to align labels and groups of form controls in a horizontal layout by adding .form-horizontal
to the form. Doing so changes .form-group
s to behave as grid rows, so no need for .row
.
<form class="form-horizontal" role="form">
<div class="form-group">
<label for="inputEmail3" class="col-sm-2 control-label">Email</label>
<div class="col-sm-10">
<input type="email" class="form-control" id="inputEmail3" placeholder="Email">
</div>
</div>
<div class="form-group">
<label for="inputPassword3" class="col-sm-2 control-label">Password</label>
<div class="col-sm-10">
<input type="password" class="form-control" id="inputPassword3" placeholder="Password">
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<div class="checkbox">
<label>
<input type="checkbox"> Remember me
</label>
</div>
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-default">Sign in</button>
</div>
</div>
</form>
Supported controls
Examples of standard form controls supported in an example form layout.
Inputs
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
.
Type declaration required
Inputs will only be fully styled if their type
is properly declared.
<input type="text" class="form-control" placeholder="Text input">
Input groups
To add integrated text or buttons before and/or after any text-based <input>
, check out the input group component.
Textarea
Form control which supports multiple lines of text. Change rows
attribute as necessary.
<textarea class="form-control" rows="3"></textarea>
Checkboxes and radios
Checkboxes are for selecting one or several options in a list while radios are for selecting one option from many.
Default (stacked)
<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>
<div class="radio">
<label>
<input type="radio" name="optionsRadios" id="optionsRadios2" value="option2">
Option two can be something else and selecting it will deselect option one
</label>
</div>
Inline checkboxes
Use the .checkbox-inline
or .radio-inline
classes on a series of checkboxes or radios for controls that 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>
Selects
Use the default option, or add multiple
to show multiple options at once.
<select class="form-control">
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
<option>5</option>
</select>
<select multiple class="form-control">
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
<option>5</option>
</select>
Static control
When you need to place plain text next to a form label within a horizontal form, use the .form-control-static
class on a <p>
.
<form class="form-horizontal" role="form">
<div class="form-group">
<label class="col-sm-2 control-label">Email</label>
<div class="col-sm-10">
<p class="form-control-static">email@example.com</p>
</div>
</div>
<div class="form-group">
<label for="inputPassword" class="col-sm-2 control-label">Password</label>
<div class="col-sm-10">
<input type="password" class="form-control" id="inputPassword" placeholder="Password">
</div>
</div>
</form>
Input focus
We remove the default outline
styles on some form controls and apply a box-shadow
in its place for :focus
.
Demo :focus
state
The above example input uses custom styles in our documentation to demonstrate the :focus
state on a .form-control
.
Disabled inputs
Add the disabled
attribute on an input to prevent user input and trigger a slightly different look.
<input class="form-control" id="disabledInput" type="text" placeholder="Disabled input here..." disabled>
Disabled fieldsets
Add the disabled
attribute to a <fieldset>
to disable all the controls within the <fieldset>
at once.
Link functionality of <a>
not impacted
This class will only change the appearance of <a class="btn btn-default">
buttons, not their functionality. Use custom JavaScript to disable links here.
Cross-browser compatibility
While Bootstrap will apply these styles in all browsers, Internet Explorer 9 and below don't actually support the disabled
attribute on a <fieldset>
. Use custom JavaScript to disable the fieldset in these browsers.
<form role="form">
<fieldset disabled>
<div class="form-group">
<label for="disabledTextInput">Disabled input</label>
<input type="text" id="disabledTextInput" class="form-control" placeholder="Disabled input">
</div>
<div class="form-group">
<label for="disabledSelect">Disabled select menu</label>
<select id="disabledSelect" class="form-control">
<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>
Validation states
Bootstrap includes validation styles for error, warning, and success states on form controls. To use, add .has-warning
, .has-error
, or .has-success
to the parent element. Any .control-label
, .form-control
, and .help-block
within that element will receive the validation styles.
<div class="form-group has-success">
<label class="control-label" for="inputSuccess1">Input with success</label>
<input type="text" class="form-control" id="inputSuccess1">
</div>
<div class="form-group has-warning">
<label class="control-label" for="inputWarning1">Input with warning</label>
<input type="text" class="form-control" id="inputWarning1">
</div>
<div class="form-group has-error">
<label class="control-label" for="inputError1">Input with error</label>
<input type="text" class="form-control" id="inputError1">
</div>
With optional icons
You can also add optional feedback icons with the addition of an extra class and the right icon.
Icons, labels, and input groups
Manual positioning of feedback icons is required for inputs without a label and for input groups with an add-on on the right. For inputs without labels, adjust the top
value. For input groups, adjust the right
value to an appropriate pixel value depending on the width of your addon.
<div class="form-group has-success has-feedback">
<label class="control-label" for="inputSuccess2">Input with success</label>
<input type="text" class="form-control" id="inputSuccess2">
<span class="glyphicon glyphicon-ok form-control-feedback"></span>
</div>
<div class="form-group has-warning has-feedback">
<label class="control-label" for="inputWarning2">Input with warning</label>
<input type="text" class="form-control" id="inputWarning2">
<span class="glyphicon glyphicon-warning-sign form-control-feedback"></span>
</div>
<div class="form-group has-error has-feedback">
<label class="control-label" for="inputError2">Input with error</label>
<input type="text" class="form-control" id="inputError2">
<span class="glyphicon glyphicon-remove form-control-feedback"></span>
</div>
Optional icons also work on horizontal and inline forms.
<form class="form-horizontal" role="form">
<div class="form-group has-success has-feedback">
<label class="control-label col-sm-3" for="inputSuccess3">Input with success</label>
<div class="col-sm-9">
<input type="text" class="form-control" id="inputSuccess3">
<span class="glyphicon glyphicon-ok form-control-feedback"></span>
</div>
</div>
</form>
<form class="form-inline" role="form">
<div class="form-group has-success has-feedback">
<label class="control-label" for="inputSuccess4">Input with success</label>
<input type="text" class="form-control" id="inputSuccess4">
<span class="glyphicon glyphicon-ok form-control-feedback"></span>
</div>
</form>
Control sizing
Set heights using classes like .input-lg
, and set widths using grid column classes like .col-lg-*
.
Height sizing
Create taller or shorter form controls that match button sizes.
<input class="form-control input-lg" type="text" placeholder=".input-lg">
<input class="form-control" type="text" placeholder="Default input">
<input class="form-control input-sm" type="text" placeholder=".input-sm">
<select class="form-control input-lg">...</select>
<select class="form-control">...</select>
<select class="form-control input-sm">...</select>
Column sizing
Wrap inputs in grid columns, or any custom parent element, to easily enforce desired widths.
<div class="row">
<div class="col-xs-2">
<input type="text" class="form-control" placeholder=".col-xs-2">
</div>
<div class="col-xs-3">
<input type="text" class="form-control" placeholder=".col-xs-3">
</div>
<div class="col-xs-4">
<input type="text" class="form-control" placeholder=".col-xs-4">
</div>
</div>
Help text
Block level help text for form controls.
<span class="help-block">A block of help text that breaks onto a new line and may extend beyond one line.</span>
Buttons
Options
Use any of the available button classes to quickly create a styled button.
<!-- Standard button -->
<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>
Sizes
Fancy larger or smaller buttons? Add .btn-lg
, .btn-sm
, or .btn-xs
for additional sizes.

<button type="button" class="btn btn-primary btn-sm">Small button</button>
<button type="button" class="btn btn-default btn-sm">Small button</button>
</p>
<p>
<button type="button" class="btn btn-primary btn-xs">Extra small button</button>
<button type="button" class="btn btn-default btn-xs">Extra small button</button>
</p>
Create block level buttons—those that span the full width of a parent— by adding .btn-block
.
<button type="button" class="btn btn-primary btn-lg btn-block">Block level button</button>
<button type="button" class="btn btn-default btn-lg btn-block">Block level button</button>
Active state
Buttons will appear pressed (with a darker background, darker border, and inset shadow) when active. For <button>
elements, this is done via :active
. For <a>
elements, it's done with .active
. However, you may use .active
on <button>
s should you need to replicate the active state progammatically.
Button element
No need to add :active
as it's a pseudo-class, but if you need to force the same appearance, go ahead and add .active
.
<button type="button" class="btn btn-primary btn-lg active">Primary button</button>
<button type="button" class="btn btn-default btn-lg active">Button</button>
Anchor element
Add the .active
class to <a>
buttons.
<a href="#" class="btn btn-primary btn-lg active" role="button">Primary link</a>
<a href="#" class="btn btn-default btn-lg active" role="button">Link</a>
Disabled state
Make buttons look unclickable by fading them back 50%.
Button element
Add the disabled
attribute to <button>
buttons.
<button type="button" class="btn btn-lg btn-primary" disabled="disabled">Primary button</button>
<button type="button" class="btn btn-default btn-lg" disabled="disabled">Button</button>
Cross-browser compatibility
If you add the disabled
attribute to a <button>
, Internet Explorer 9 and below will render text gray with a nasty text-shadow that we cannot fix.
Anchor element
Add the .disabled
class to <a>
buttons.
<a href="#" class="btn btn-primary btn-lg disabled" role="button">Primary link</a>
<a href="#" class="btn btn-default btn-lg disabled" role="button">Link</a>
We use .disabled
as a utility class here, similar to the common .active
class, so no prefix is required.
Link functionality not impacted
This class will only change the <a>
's appearance, not its functionality. Use custom JavaScript to disable links here.
Context-specific usage
While button classes can be used on <a>
and <button>
elements, only <button>
elements are supported within our nav and navbar components.
Button tags
Use the button classes on an <a>
, <button>
, or <input>
element.
<a class="btn btn-default" href="#" role="button">Link</a>
<button class="btn btn-default" type="submit">Button</button>
<input class="btn btn-default" type="button" value="Input">
<input class="btn btn-default" type="submit" value="Submit">
Cross-browser rendering
As a best practice, we highly recommend using the <button>
element whenever possible to ensure matching cross-browser rendering.
Among other things, there's a Firefox bug that prevents us from setting the line-height
of <input>
-based buttons, causing them to not exactly match the height of other buttons on Firefox.
Images
Responsive images
Images in Bootstrap 3 can be made responsive-friendly via the addition of the .img-responsive
class. This applies max-width: 100%;
and height: auto;
to the image so that it scales nicely to the parent element.
<img src="..." class="img-responsive" alt="Responsive image">
Image shapes
Add classes to an <img>
element to easily style images in any project.
Cross-browser compatibility
Keep in mind that Internet Explorer 8 lacks support for rounded corners.
<img src="..." alt="..." class="img-rounded">
<img src="..." alt="..." class="img-circle">
<img src="..." alt="..." class="img-thumbnail">
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.
Tabs
Note the .nav-tabs
class requires the .nav
base class.
<ul class="nav nav-tabs">
<li class="active"><a href="#">Home</a></li>
<li><a href="#">Profile</a></li>
<li><a href="#">Messages</a></li>
</ul>
Requires JavaScript tabs plugin
For tabs with tabbable areas, you must use the tabs JavaScript plugin.
Pills
Take that same HTML, but use .nav-pills
instead:
<ul class="nav nav-pills">
<li class="active"><a href="#">Home</a></li>
<li><a href="#">Profile</a></li>
<li><a href="#">Messages</a></li>
</ul>
Pills are also vertically stackable. Just add .nav-stacked
.
<ul class="nav nav-pills nav-stacked">
...
</ul>
Justified
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.
<ul class="nav nav-tabs nav-justified">
...
</ul>
<ul class="nav nav-pills nav-justified">
...
</ul>
Disabled links
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.
<ul class="nav nav-pills">
...
<li class="disabled"><a href="#">Disabled link</a></li>
...
</ul>
Using dropdowns
Add dropdown menus with a little extra HTML and the dropdowns JavaScript plugin.
Tabs with dropdowns
<ul class="nav nav-tabs">
...
<li class="dropdown">
<a class="dropdown-toggle" data-toggle="dropdown" href="#">
Dropdown <span class="caret"></span>
</a>
<ul class="dropdown-menu">
...
</ul>
</li>
...
</ul>
Pills with dropdowns
<ul class="nav nav-pills">
...
<li class="dropdown">
<a class="dropdown-toggle" data-toggle="dropdown" href="#">
Dropdown <span class="caret"></span>
</a>
<ul class="dropdown-menu">
...
</ul>
</li>
...
</ul>
Helper classes
Contextual colors
Convey meaning through color with a handful of emphasis utility classes. These may also be applied to links and will darken on hover just like our default link styles.
Fusce dapibus, tellus ac cursus commodo, tortor mauris nibh.
Nullam id dolor id nibh ultricies vehicula ut id elit.
Duis mollis, est non commodo luctus, nisi erat porttitor ligula.
Maecenas sed diam eget risus varius blandit sit amet non magna.
Etiam porta sem malesuada magna mollis euismod.
Donec ullamcorper nulla non metus auctor fringilla.
<p class="text-muted">...</p>
<p class="text-primary">...</p>
<p class="text-success">...</p>
<p class="text-info">...</p>
<p class="text-warning">...</p>
<p class="text-danger">...</p>
Dealing with specificity
Sometimes emphasis classes cannot be applied due to the specificity of another selector. In most cases, a sufficient workaround is to wrap your text in a <span>
with the class.
Contextual backgrounds
Similar to the contextual text color classes, easily set the background of an element to any contextual class. Anchor components will darken on hover, just like the text classes.
Nullam id dolor id nibh ultricies vehicula ut id elit.
Duis mollis, est non commodo luctus, nisi erat porttitor ligula.
Maecenas sed diam eget risus varius blandit sit amet non magna.
Etiam porta sem malesuada magna mollis euismod.
Donec ullamcorper nulla non metus auctor fringilla.
<p class="bg-primary">...</p>
<p class="bg-success">...</p>
<p class="bg-info">...</p>
<p class="bg-warning">...</p>
<p class="bg-danger">...</p>
Close icon
Use the generic close icon for dismissing content like modals and alerts.
<button type="button" class="close" aria-hidden="true">×</button>
Carets
Use carets to indicate dropdown functionality and direction. Note that the default caret will reverse automatically in dropup menus.
<span class="caret"></span>
Quick floats
Float an element to the left or right with a class. !important
is included to avoid specificity issues. Classes can also be used as mixins.
<div class="pull-left">...</div>
<div class="pull-right">...</div>
// Classes
.pull-left {
float: left !important;
}
.pull-right {
float: right !important;
}
// Usage as mixins
.element {
.pull-left();
}
.another-element {
.pull-right();
}
Not for use in navbars
To align components in navbars with utility classes, use .navbar-left
or .navbar-right
instead. See the navbar docs for details.
Center content blocks
Set an element to display: block
and center via margin
. Available as a mixin and class.
<div class="center-block">...</div>
// Classes
.center-block {
display: block;
margin-left: auto;
margin-right: auto;
}
// Usage as mixins
.element {
.center-block();
}
Clearfix
Clear the float
on any element with the .clearfix
class. Utilizes the micro clearfix as popularized by Nicolas Gallagher. Can also be used as a mixin.
<!-- Usage as a class -->
<div class="clearfix">...</div>
// Mixin itself
.clearfix() {
&:before,
&:after {
content: " ";
display: table;
}
&:after {
clear: both;
}
}
// Usage as a Mixin
.element {
.clearfix();
}
Showing and hiding content
Force an element to be shown or hidden (including for screen readers) with the use of .show
and .hidden
classes. These classes use !important
to avoid specificity conflicts, just like the quick floats. They are only available for block level toggling. They can also be used as mixins.
.hide
is available, but it does not always affect screen readers and is deprecated as of v3.0.1. Use .hidden
or .sr-only
instead.
Furthermore, .invisible
can be used to toggle only the visibility of an element, meaning its display
is not modified and the element can still affect the flow of the document.
<div class="show">...</div>
<div class="hidden">...</div>
// Classes
.show {
display: block !important;
}
.hidden {
display: none !important;
visibility: hidden !important;
}
.invisible {
visibility: hidden;
}
// Usage as mixins
.element {
.show();
}
.another-element {
.hidden();
}
Screen reader content
Hide an element to all devices except screen readers with .sr-only
. Necessary for following accessibility best practices. Can also be used as a mixin.
<a class="sr-only" href="#content">Skip to main content</a>
// Usage as a Mixin
.skip-navigation {
.sr-only();
}
Image replacement
Utilize the .text-hide
class or mixin to help replace an element's text content with a background image.
<h1 class="text-hide">Custom heading</h1>
// Usage as a Mixin
.heading {
.text-hide();
}
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>
.
<span class="glyphicon glyphicon-search"></span>
Examples
Use them in buttons, button groups for a toolbar, navigation, or prepended form inputs.
<button type="button" class="btn btn-default btn-lg">
<span class="glyphicon glyphicon-star"></span> Star
</button>
