There's a newer version of Bootstrap 4!

Utilities

Bootstrap includes dozens of utilities—classes with a single purpose to reduce the frequency of highly repetitive declarations.

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.

Etiam porta sem malesuada ultricies vehicula.

<p class="text-muted">Fusce dapibus, tellus ac cursus commodo, tortor mauris nibh.</p>
<p class="text-primary">Nullam id dolor id nibh ultricies vehicula ut id elit.</p>
<p class="text-success">Duis mollis, est non commodo luctus, nisi erat porttitor ligula.</p>
<p class="text-info">Maecenas sed diam eget risus varius blandit sit amet non magna.</p>
<p class="text-warning">Etiam porta sem malesuada magna mollis euismod.</p>
<p class="text-danger">Donec ullamcorper nulla non metus auctor fringilla.</p>
<p class="text-white">Etiam porta sem malesuada ultricies vehicula.</p>

Contextual text classes also work well on anchors with the provided hover and focus states. Note that the .text-white class has no link styling.

<a href="#" class="text-muted">Muted link</a>
<a href="#" class="text-primary">Primary link</a>
<a href="#" class="text-success">Success link</a>
<a href="#" class="text-info">Info link</a>
<a href="#" class="text-warning">Warning link</a>
<a href="#" class="text-danger">Danger link</a>

Similar to the contextual text color classes, easily set the background of an element to any contextual class. Anchor components will darken on hover, just like the text classes. Background utilities do not set color, so in some cases you’ll want to use .text-* utilities.

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.
Cras mattis consectetur purus sit amet fermentum.
Cras mattis consectetur purus sit amet fermentum.
<div class="bg-primary text-white">Nullam id dolor id nibh ultricies vehicula ut id elit.</div>
<div class="bg-success text-white">Duis mollis, est non commodo luctus, nisi erat porttitor ligula.</div>
<div class="bg-info text-white">Maecenas sed diam eget risus varius blandit sit amet non magna.</div>
<div class="bg-warning text-white">Etiam porta sem malesuada magna mollis euismod.</div>
<div class="bg-danger text-white">Donec ullamcorper nulla non metus auctor fringilla.</div>
<div class="bg-inverse text-white">Cras mattis consectetur purus sit amet fermentum.</div>
<div class="bg-faded">Cras mattis consectetur purus sit amet fermentum.</div>

Dealing with specificity

Sometimes contextual classes cannot be applied due to the specificity of another selector. In some cases, a sufficient workaround is to wrap your element’s content in a <div> with the class.

Conveying meaning to assistive technologies

Using color to add meaning 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 (e.g. the visible text), or is included through alternative means, such as additional text hidden with the .sr-only class.
