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>

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>

Alignment classes

Easily realign text to components with text alignment classes.

Left aligned text.

Center aligned text.

Right aligned text.

No wrap 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-nowrap">No wrap text.</p>

Transformation classes

Transform text in components with text capitalization classes.

Lowercased text.

Uppercased text.

Capitalized text.

<p class="text-lowercase">Lowercased text.</p>
<p class="text-uppercase">Uppercased text.</p>
<p class="text-capitalize">Capitalized 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 and to users of assistive technologies.

Basic abbreviation

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>.

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
    • Ac tristique libero volutpat at
  • Faucibus porta lacus fringilla vel
  • Aenean sit amet erat nunc
  • Eget porttitor lorem
<ul>
  <li>...</li>
</ul>

Ordered

A list of items in which the order does explicitly matter.

  1. Lorem ipsum dolor sit amet
  2. Consectetur adipiscing elit
  3. Integer molestie lorem at massa
  4. Facilisis in pretium nisl aliquet
  5. Nulla volutpat aliquam velit
  6. Faucibus porta lacus fringilla vel
  7. Aenean sit amet erat nunc
  8. 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>

Buttons

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

Link 
<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">

Links acting as buttons

If the <a> elements are used to act as buttons – triggering in-page functionality, rather than navigating to another document or section within the current page – they should also be given an appropriate role="button".

Options

Use any of the available button classes to quickly create a styled button.


<!-- Standard 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>

<!-- 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>

Conveying meaning to assistive technologies

Using color to add meaning to a button only provides a visual indication, which will not be conveyed to users of assistive technologies – such as screen readers. Ensure that information denoted by the color is either obvious from the content itself (the visible text of the button), or is included through alternative means, such as additional text hidden with the .sr-only class.

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 (and include the aria-pressed="true" attribute) should you need to replicate the active state programmatically.

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>

Disabled state

Make buttons look unclickable by fading them back with opacity.

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 text-shadow.

  	     <td>Table Cell Data...</td>
  	     <td>Table Cell Data...</td>
  	   </tr>
  	</tbody>
  </table>
</div>

Tabs

Tabs should be used in instances where there is a large amount of content or list items that can be categorized but don't necessarily need separate web pages.

Tab 1 content...

Tab 2 content...

  <!-- Nav tabs -->
  <ul class="nav nav-tabs" role="tablist">
    <li role="presentation" class="active"><a href="#tab1" aria-controls="tab1" role="tab" data-toggle="tab">Tab 1</a></li>
    <li role="presentation"><a href="#tab2" aria-controls="tab2" role="tab" data-toggle="tab">Tab 2</a></li>
  </ul>

  <!-- Tab panes -->
  <div class="tab-content">
     <div role="tabpanel" class="tab-pane active" id="tab1">Tab 1 content...</div>
     <div role="tabpanel" class="tab-pane" id="tab2">Tab 2 content...</div>
  </div>

Alerts

Alerts are typically used in the cases of successful form submission or when errors in validation occur. They can also be used to for notification. For example, a warning can notify users of upcoming system maintenace.

<div class="alert alert-success" role="alert">...</div>
<div class="alert alert-warning" role="alert">...</div>
<div class="alert alert-danger" role="alert">...</div>
