Typography

Headings

All HTML headings, <h1> through <h6> are available.

h1. Heading 1

h2. Heading 2

h3. Heading 3

h4. Heading 4

h5. Heading 5
h6. Heading 6

Body copy

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>

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>

Built with Less

The typographic scale is based on two LESS variables in variables.less: @baseFontSize and @baseLineHeight. 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.

Emphasis

Make use of HTML’s default emphasis tags with lightweight styles.

<small>

For de-emphasizing inline or blocks of text, use the small tag.

This line of text is meant to be treated as fine print.

<p>
  <small>This line of text is meant to be treated as fine print.</small>
</p>

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>

Heads up! 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.

<p class="text-left">Left aligned text.</p>
<p class="text-center">Center aligned text.</p>
<p class="text-right">Right aligned text.</p>

Emphasis classes

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.

Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis.

Duis mollis, est non commodo luctus, nisi erat porttitor ligula.

<p class="muted">Fusce dapibus, tellus ac cursus commodo, tortor mauris nibh.</p>
<p class="text-warning">Etiam porta sem malesuada magna mollis euismod.</p>
<p class="text-error">Donec ullamcorper nulla non metus auctor fringilla.</p>
<p class="text-info">Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis.</p>
<p class="text-success">Duis mollis, est non commodo luctus, nisi erat porttitor ligula.</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.

<abbr>

For expanded text on long hover of an abbreviation, include the title attribute.

An abbreviation of the word attribute is attr.

<abbr title="attribute">attr</abbr>

<abbr class="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.

<address>

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 <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>

Alternate displays

Use .pull-right for a floated, right-aligned blockquote.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.

Someone famous in Source Title 

<blockquote class="pull-right">
  ...
</blockquote>

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.

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

<dl class="dl-horizontal">
  <dt>...</dt>
  <dd>...</dd>
</dl>

Heads up!
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.

Code

Inline

Wrap inline snippets of code with <code>.

For example, <section> should be wrapped as inline. 
For example, <code>&lt;section&gt;</code> should be wrapped as inline.

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>
  &lt;p&gt;Sample text here...&lt;/p&gt;
</pre>

Heads up! Be sure to keep code within <pre> tags as close to the left as possible; it will render all tabs.

You may optionally add the .pre-scrollable class which will set a max-height of 350px and provide a y-axis scrollbar.

Tables

Default styles

For basic styling—light padding and only horizontal dividers—add the base class .table to any <table>.

# First Name Last Name Username

List of supported table HTML elements and how they should be used.

Tag Description
<table> Wrapping element for displaying data in a tabular format
<thead> Container element for table header rows (<tr>) to label table columns
<tbody> Container element for table rows (<tr>) in the body of the table

Forms

Default styles

Individual form controls receive styling, but without any required base class on the <form> or large changes in markup. Results in stacked, left-aligned labels on top of form controls.

Legend



Example block-level help text here.


<form>
  <fieldset>
    <legend>Legend</legend>
    <label>Label name</label>
    <input type="text" placeholder="Type something…">
    <span class="help-block">Example block-level help text here.</span>
    <label class="checkbox">
      <input type="checkbox"> Check me out
    </label>
    <button type="submit" class="btn">Submit</button>
  </fieldset>
</form>

Optional layouts

Included with Bootstrap are three optional form layouts for common use cases.

Search form

Add .form-search to the form and .search-query to the <input> for an extra-rounded text input.



<form class="form-search">
  <input type="text" class="input-medium search-query">
  <button type="submit" class="btn">Search</button>
</form>

Inline form

Add .form-inline for left-aligned labels and inline-block controls for a compact layout.





<form class="form-inline">
  <input type="text" class="input-small" placeholder="Email">
  <input type="password" class="input-small" placeholder="Password">
  <label class="checkbox">
    <input type="checkbox"> Remember me
  </label>
  <button type="submit" class="btn">Sign in</button>
</form>

Horizontal 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:

  • Add .form-horizontal to the form
  • Wrap labels and controls in .control-group
  • Add .control-label to the label
  • Wrap any associated controls in .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>
  </div>
  <div class="control-group">
    <div class="controls">
      <label class="checkbox">
        <input type="checkbox"> Remember me
      </label>
      <button type="submit" class="btn">Sign in</button>
    </div>
  </div>
</form>

Supported form 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.

Requires the use of a specified type at all times.


<input type="text" placeholder="Text input">

Textarea

Form control which supports multiple lines of text. Change rows attribute as necessary.


<textarea 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)





<label class="checkbox">
  <input type="checkbox" value="">
  Option one is this and that—be sure to include why it's great
</label>

<label class="radio">
  <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>
<label class="radio">
  <input type="radio" name="optionsRadios" id="optionsRadios2" value="option2">
  Option two can be something else and selecting it will deselect option one
</label>

Inline checkboxes

Add the .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>

Selects

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>

Extending form controls

Adding on top of existing browser controls, Bootstrap includes other useful form components.

Prepended and appended inputs

Add text or buttons before or after any text-based input. Do note that select elements are not supported here.

Default options

Wrap an .add-on and an input with one of two classes to prepend or append text to an input.

@


.00 

<div class="input-prepend">
  <span class="add-on">@</span>
  <input class="span2" id="prependedInput" type="text" placeholder="Username">
</div>
<div class="input-append">
  <input class="span2" id="appendedInput" type="text">
  <span class="add-on">.00</span>
</div>

Combined

Use both classes and two instances of .add-on to prepend and append an input.

$

.00 

<div class="input-prepend input-append">
  <span class="add-on">$</span>
  <input class="span2" id="appendedPrependedInput" type="text">
  <span class="add-on">.00</span>
</div>

Buttons instead of text

Instead of a <span> with text, use a .btn to attach a button (or two) to an input.


<div class="input-append">
  <input class="span2" id="appendedInputButton" type="text">
  <button class="btn" type="button">Go!</button>
</div>



<div class="input-append">
  <input class="span2" id="appendedInputButtons" type="text">
  <button class="btn" type="button">Search</button>
  <button class="btn" type="button">Options</button>
</div>

Button dropdowns


<div class="input-append">
  <input class="span2" id="appendedDropdownButton" type="text">
  <div class="btn-group">
    <button class="btn dropdown-toggle" data-toggle="dropdown">
      Action
      <span class="caret"></span>
    </button>
    <ul class="dropdown-menu">
      ...
    </ul>
  </div>
</div>




<div class="input-prepend">
  <div class="btn-group">
    <button class="btn dropdown-toggle" data-toggle="dropdown">
      Action
      <span class="caret"></span>
    </button>
    <ul class="dropdown-menu">
      ...
    </ul>
  </div>
  <input class="span2" id="prependedDropdownButton" type="text">
</div>




<div class="input-prepend input-append">
  <div class="btn-group">
    <button class="btn dropdown-toggle" data-toggle="dropdown">
      Action
      <span class="caret"></span>
    </button>
    <ul class="dropdown-menu">
      ...
    </ul>
  </div>
  <input class="span2" id="appendedPrependedDropdownButton" type="text">
  <div class="btn-group">
    <button class="btn dropdown-toggle" data-toggle="dropdown">
      Action
      <span class="caret"></span>
    </button>
    <ul class="dropdown-menu">
      ...
    </ul>
  </div>
</div>

Segmented dropdown groups



<form>
  <div class="input-prepend">
    <div class="btn-group">...</div>
    <input type="text">
  </div>
  <div class="input-append">
    <input type="text">
    <div class="btn-group">...</div>
  </div>
</form>

Search form



<form class="form-search">
  <div class="input-append">
    <input type="text" class="span2 search-query">
    <button type="submit" class="btn">Search</button>
  </div>
  <div class="input-prepend">
    <button type="submit" class="btn">Search</button>
    <input type="text" class="span2 search-query">
  </div>
</form>

Control sizing

Use relative sizing classes like .input-large or match your inputs to the grid column sizes using .span* classes.

Block level inputs

Make any <input> or <textarea> element behave like a block level element.

<input class="input-block-level" type="text" placeholder=".input-block-level">

Relative sizing






<input class="input-mini" type="text" placeholder=".input-mini">
<input class="input-small" type="text" placeholder=".input-small">
<input class="input-medium" type="text" placeholder=".input-medium">
<input class="input-large" type="text" placeholder=".input-large">
<input class="input-xlarge" type="text" placeholder=".input-xlarge">
<input class="input-xxlarge" type="text" placeholder=".input-xxlarge">

Heads up! In future versions, we’ll be altering the use of these relative input classes to match our button sizes. For example, .input-large will increase the padding and font-size of an input.

Grid sizing

Use .span1 to .span12 for inputs that match the same sizes of the grid columns.






<input class="span1" type="text" placeholder=".span1">
<input class="span2" type="text" placeholder=".span2">
<input class="span3" type="text" placeholder=".span3">
<select class="span1">
  ...
</select>
<select class="span2">
  ...
</select>
<select class="span3">
  ...
</select>

For multiple grid inputs per line, use the .controls-row modifier class for proper spacing. It floats the inputs to collapse white-space, sets the proper margins, and clears the float.





<div class="controls">
  <input class="span5" type="text" placeholder=".span5">
</div>
<div class="controls controls-row">
  <input class="span4" type="text" placeholder=".span4">
  <input class="span1" type="text" placeholder=".span1">
</div>
...

Uneditable inputs

Present data in a form that’s not editable without using actual form markup.

Some value here
<span class="input-xlarge uneditable-input">Some value here</span>

Form actions

End a form with a group of actions (buttons). When placed within a .form-actions, 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>

Help text

Inline and block level support for help text that appears around form controls.

Inline help

Inline help text
<input type="text"><span class="help-inline">Inline help text</span>

Block help


A longer block of help text that breaks onto a new line and may extend beyond one line.
<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>

Form control states

Provide feedback to users or visitors with basic feedback states on form controls and labels.

Input focus

We remove the default outline styles on some form controls and apply a box-shadow in its place for :focus.


<input class="input-xlarge" id="focusedInput" type="text" value="This is focused...">

Invalid inputs

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="span3" type="email" required>

Disabled inputs

Add the disabled attribute on an input to prevent user input and trigger a slightly different look.


<input class="input-xlarge" id="disabledInput" type="text" placeholder="Disabled input here..." disabled>

Validation states

Bootstrap includes validation styles for error, warning, info, and success messages. To use, add the appropriate class to the surrounding .control-group.


Something may have gone wrong


Please correct the error


Username is taken


Woohoo! 

<div class="control-group warning">
  <label class="control-label" for="inputWarning">Input with warning</label>
  <div class="controls">
    <input type="text" id="inputWarning">
    <span class="help-inline">Something may have gone wrong</span>
  </div>
</div>

<div class="control-group error">
  <label class="control-label" for="inputError">Input with error</label>
  <div class="controls">
    <input type="text" id="inputError">
    <span class="help-inline">Please correct the error</span>
  </div>
</div>

<div class="control-group info">
  <label class="control-label" for="inputInfo">Input with info</label>
  <div class="controls">
    <input type="text" id="inputInfo">
    <span class="help-inline">Username is already taken</span>
  </div>
</div>

<div class="control-group success">
  <label class="control-label" for="inputSuccess">Input with success</label>
  <div class="controls">
    <input type="text" id="inputSuccess">
    <span class="help-inline">Woohoo!</span>
  </div>
</div>

Buttons

Default buttons

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.

Button class=”” Description
btn Standard gray button with gradient
btn btn-primary Provides extra visual weight and identifies the primary action in a set of buttons
btn btn-info Used as an alternative to the default styles
btn btn-success Indicates a successful or positive action
btn btn-warning Indicates caution should be taken with this action
btn btn-danger Indicates a dangerous or potentially negative action
btn btn-inverse Alternate dark gray button, not tied to a semantic action or use
btn btn-link Deemphasize a button by making it look like a link while maintaining button behavior

Cross browser compatibility

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.

Button sizes

Fancy larger or smaller buttons? Add .btn-large, .btn-small, or .btn-mini for additional sizes.





<p>
  <button class="btn btn-large btn-primary" type="button">Large button</button>
  <button class="btn btn-large" type="button">Large button</button>

Create block level buttons—those that span the full width of a parent— by adding .btn-block.


<button class="btn btn-large btn-block btn-primary" type="button">Block level button</button>
<button class="btn btn-large btn-block" type="button">Block level button</button>

Disabled state

Make buttons look unclickable by fading them back 50%.

Anchor element

Add the .disabled class to <a> buttons.

Primary link
Link 

<a href="#" class="btn btn-large btn-primary disabled">Primary link</a>
<a href="#" class="btn btn-large disabled">Link</a>

Heads up!
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.

Button element

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>Button</button>

One class, multiple tags

Use the .btn class on an <a>, <button>, or <input> element.

Link



<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, try to match the element for your context to ensure matching cross-browser rendering. If you have an input, use an <input type="submit"> for your button.

Images

Add classes to an <img> element to easily style images in any project.



<img src="....." class="img-rounded">
<img src="....." class="img-circle">
<img src="....." class="img-polaroid">

Heads up! .img-rounded and .img-circle do not work in IE7-8 due to lack of border-radius support.

Glyphicons attribution

Glyphicons Halflings are normally not available for free, but an arrangement between Bootstrap and the Glyphicons creators 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.

How to use

All icons require an <i> tag with a unique class, prefixed with icon-. To use, place the following code just about anywhere:

<i class="icon-search"></i>

There are also styles available for inverted (white) icons, made ready with one extra class. We will specifically enforce this class on hover and active states for nav and dropdown links.

<i class="icon-search icon-white"></i>

Heads up!
When using beside strings of text, as in buttons or nav links, be sure to leave a space after the <i> tag for proper spacing.

Icon examples

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