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.

Body copy

Bootstrap's global default font-size is 14px, with a line-height of 1.7em. This is applied to the <body> and all paragraphs. In addition, <p> (paragraphs) receive a bottom margin of half their line-height (9px 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. 
<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.

<em>

For emphasizing a snippet of text with stress
The following snippet of text is rendered as italicized text. 
<em>rendered as italicized text</em>

<strong>

For emphasizing a snippet of text with important
The following snippet of text is rendered as bold text. 
<strong>rendered as bold text</strong>

<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>
  Note: 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.

Notice Styles

Use the <p> tag with .success, .warning, .info or .error classes.

Nullam quis risus eget urna mollis ornare vel eu leo. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus.

<p class="success">...</p>

Nullam quis risus eget urna mollis ornare vel eu leo. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus.

<p class="info">...</p>

Nullam quis risus eget urna mollis ornare vel eu leo. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus.

<p class="warning">...</p>

Nullam quis risus eget urna mollis ornare vel eu leo. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus.

<p class="error">...</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="attribute" class="initialism">attr</abbr>

Addresses

Stylized implementation of HTML's element to present contact information for the nearest ancestor or the entire body of work.

<address>

Preserve formatting by ending all lines with <br>.
Twitter, Inc. 795 Folsom Ave, Suite 600 San Francisco, CA 94107 P: (123) 456-7890
Full Name first.last@gmail.com

Blockquotes

For quoting blocks of content from another source within your document.

Default blockqoute

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>

  Note: 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.

Horizontal description

Code

Inline

Wrap inline snippets of code with <code>.
For example, <section> should be wrapped as inline.
For example, <code><section></code> should be wrapped as inline.
Note: 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.

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>

Prettify

To add colored syntax highlight to the <pre> tag, then use the .prettyprint class or the .prettyprint linenums class. 
<?php /** Begin Debug **/ if ($gantry->countModules('debug')) : ?>
    <div id="rt-debug">
    <div class="rt-container">
      <?php echo $gantry->displayModules('debug','standard','standard'); ?>
      <div class="clear"></div>
    </div>
  </div>
  <?php /** End Debug **/ endif; ?>
<pre class="prettyprint linenums"><?php /** Begin Debug **/ if ($gantry->countModules('debug')) : ?>
  <div id="rt-debug">
    <div class="rt-container">
      <?php echo $gantry->displayModules('debug','standard','standard'); ?>
      <div class="clear"></div>
    </div>
  </div>
  <?php /** End Debug **/ endif; ?></pre>

    <td>01/04/2012</td>
    <td>Approved</td>
  </tr>
...

Supported table markup

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
<tr> Container element for a set of table cells (<td> or <th>) that appears on a single row
<td> Default table cell
<th> Special table cell for column (or row, depending on scope and placement) labels Must be used within a <thead>

      <td>...</td>
      <td>...</td>
    </tr>

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>
</p>
<p>
  <button class="btn btn-primary" type="button">Default button</button>
  <button class="btn" type="button">Default button</button>
</p>
<p>
  <button class="btn btn-small btn-primary" type="button">Small button</button>
  <button class="btn btn-small" type="button">Small button</button>
</p>
<p>
  <button class="btn btn-mini btn-primary" type="button">Mini button</button>
  <button class="btn btn-mini" type="button">Mini button</button>
</p>
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>
  Note: We use .disabled as a utility class here, similar to the common .active class, so no prefix is required.

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.
