Base CSS Basic HTML elements are styled and enhanced with extensible classes to provide a fresh, consistent look and feel.

Typographic scale

The entire typographic grid is based on two Less variables in our variables.less file: @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 math, to create the margins, paddings, and line-heights of all our type and more.

Example body text

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 ut id elit.

Vivamus sagittis lacus vel augue laoreet rutrum faucibus dolor auctor. Duis mollis, est non commodo luctus, nisi erat porttitor ligula, eget lacinia odio sem nec elit. Donec sed odio dui.

Blockquotes

Element Usage Optional
<blockquote> Block-level element for quoting content from another source

Add cite attribute for source URL

Use .pull-left and .pull-right classes for floated options
<small> Optional element for adding a user-facing citation, typically an author with title of work Place the <cite> around the title or name of source

To include a blockquote, wrap <blockquote> around any HTML as the quote. For straight quotes we recommend a <p>.

Include an optional <small> element to cite your source and you'll get an em dash &mdash; before it for styling purposes.

  1. <blockquote>
  2. <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante venenatis.</p>
  3. <small>Someone famous</small>
  4. </blockquote>

Example blockquotes

Default blockquotes are styled as such:

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

Someone famous in Body of work

To float your blockquote to the right, add class="pull-right":

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

Someone famous in Body of work

Donec id elit non mi porta gravida at eget metus.

Components Dozens of reusable components are built into Bootstrap to provide navigation, alerts, popovers, and much more.

Button groups

Use button groups to join multiple buttons together as one composite component. Build them with a series of <a> or <button> elements.

Best practices

We recommend the following guidelines for using button groups and toolbars:

Related Button groups with dropdowns (see below) should be called out separately and always include a dropdown caret to indicate intended behavior.

Default example

Here's how the HTML looks for a standard button group built with anchor tag buttons:

  1. <div class="btn-group">
  2. <button class="btn">1</button>
  3. <button class="btn">2</button>
  4. <button class="btn">3</button>
  5. </div>

Toolbar example

Combine sets of <div class="btn-group"> into a <div class="btn-toolbar"> for more complex components.

  1. <div class="btn-toolbar">
  2. <div class="btn-group">
  3. ...
  4. </div>
  5. </div>

Checkbox and radio flavors

Button groups can also function as radios, where only one button may be active, or checkboxes, where any number of buttons may be active. View the Javascript docs for that.

Dropdowns in button groups

Heads up! Buttons with dropdowns must be individually wrapped in their own .btn-group within a .btn-toolbar for proper rendering.
