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>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>

- Integer molestie lorem at massa
- Facilisis in pretium nisl aliquet
- Nulla volutpat aliquam velit
- Phasellus iaculis neque

- 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.

- Euismod
- Vestibulum id ligula porta felis euismod semper eget lacinia odio sem nec elit.
- Donec id elit non mi porta gravida at eget metus.

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.
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.
<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>
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 active">Primary button</button>
<button type="button" class="btn btn-default 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.
Alerts
Provide contextual feedback messages for typical user actions with the handful of available and flexible alert messages. For inline dismissal, use the alerts jQuery plugin.
Examples
Wrap any text and an optional dismiss button in .alert and one of the four contextual classes (e.g., .alert-success) for basic alert messages.
No default class
Alerts don't have default classes, only base and modifier classes. A default gray alert doesn't make too much sense, so you're required to specify a type via contextual class. Choose from success, info, warning, or danger.
<div class="alert alert-success">...</div>
<div class="alert alert-info">...</div>
<div class="alert alert-warning">...</div>
<div class="alert alert-danger">...</div>
Dismissable alerts
Build on any alert by adding an optional .alert-dismissable and close button.
<div class="alert alert-warning alert-dismissable">
<button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button>
<strong>Warning!</strong> Better check yourself, you're not looking too good.
</div>
Ensure proper behavior across all devices
Be sure to use the <button> element with the data-dismiss="alert" data attribute.
Links in alerts
Use the .alert-link utility class to quickly provide matching colored links within any alert.
<div class="alert alert-success">
<a href="#" class="alert-link">...</a>
</div>
<div class="alert alert-info">
<a href="#" class="alert-link">...</a>
</div>
<div class="alert alert-warning">
<a href="#" class="alert-link">...</a>
</div>
<div class="alert alert-danger">
<a href="#" class="alert-link">...</a>
</div>
