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>
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.
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.

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>

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 in <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 display: 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. Starts off stacked like default <dl>
s, but when the navbar expands, so do these.
<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 with text-overflow
. In narrower viewports, they will change to the default stacked layout.
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.

Use .table-striped
to add zebra-striping to any table row within the <tbody>
.
Striped tables are styled via the :nth-child
CSS selector, which is not available in Internet Explorer 8.

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.

Use any of the available button classes to quickly create a styled button.
<!-- 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>
Fancy larger or smaller buttons? Add .btn-lg
, .btn-sm
, or .btn-xs
for additional sizes.
<p>
<button type="button" class="btn btn-primary btn-lg">Large button</button>
<button type="button" class="btn btn-default btn-lg">Large button</button>
</p>
<p>
<button type="button" class="btn btn-primary">Default button</button>
<button type="button" class="btn btn-default">Default button</button>
</p>
<p>
<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>
Make buttons look unclickable by fading them back 50%.
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>
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.
Add the .disabled
class to <a>
buttons.
<a href="#" class="btn btn-primary btn-lg disabled">Primary link</a>
<a href="#" class="btn btn-default btn-lg disabled">Link</a>
We use .disabled
as a utility class here, similar to the common .active
class, so no prefix is required.
This class will only change the <a>
's appearance, not its functionality. Use custom JavaScript to disable links here.
Use the button classes on an <a>
, <button>
, or <input>
element.
<a class="btn btn-default" href="#">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">
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.
