NEW TWO COLUMN TEMPLATE

Contextual colors

Convey meaning through color with a handful of emphasis utility classes. These may also be applied to links and will darken on hover just like our default link styles.

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.


<p class="text-muted">...</p>
<p class="text-primary">...</p>
<p class="text-success">...</p>
<p class="text-info">...</p>
<p class="text-warning">...</p>
<p class="text-danger">...</p>

Dealing with specificity

Sometimes emphasis classes cannot be applied due to the specificity of another selector. In most cases, a sufficient workaround is to wrap your text in a <span> with the class.

Close icon

Use the generic close icon for dismissing content like modals and alerts.


<button type="button" class="close" aria-hidden="true">&times;</button>

Carets

Use carets to indicate dropdown functionality and direction. Note that the default caret will reverse automatically in dropup menus.


<span class="caret"></span>

Quick floats

Float an element to the left or right with a class. !important is included to avoid specificity issues.


<div class="pull-left">...</div>
<div class="pull-right">...</div>


// Classes
.pull-left {
  float:left !important;
}
.pull-right {
  float:right !important;
}

Not for use in navbars

To align components in navbars with utility classes, use .navbar-left or .navbar-right instead. See the navbar docs for details.

Center content blocks

Set an element to display: block and center via margin.


  <div class="center-block">...</div>


// Classes
.center-block {
  display: block;
  margin-left: auto;
  margin-right: auto;
}

Clearfix

Clear the float on any element with the .clearfix class. Utilizes the micro clearfix as popularized by Nicolas Gallagher.


<!-- Usage as a class -->
<div class="clearfix">...</div>

Showing and hiding content

Force an element to be shown or hidden (including for screen readers) with the use of .show and .hidden classes. These classes use !important to avoid specificity conflicts, just like the quick floats. They are only available for block level toggling.

.hide is available, but it does not always affect screen readers and is deprecated as of v3.0.1. Use .hidden or .sr-only instead.

Furthermore, .invisible can be used to toggle only the visibility of an element, meaning its display is not modified and the element can still affect the flow of the document.


<div class="show">...</div>
<div class="hidden">...</div>


// Classes
.show {
  display: block !important;
}
.hidden {
  display: none !important;
  visibility: hidden !important;
}
.invisible {
  visibility: hidden;
}

Screen reader content

Hide an element to all devices except screen readers with .sr-only. Necessary for following accessibility best practices.

<a class="sr-only" href="#content">Skip to main content</a>

Image replacement

Utilize the .text-hide class to help replace an element's text content with a background image.


<h1 class="text-hide">Custom heading</h1>
