Color

Add a little, or a lot of, color to your site or application.

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

Please refer to the Accessiblity notes about conveying meaning with color.

Contents

Text

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">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>

Contextual text classes also work well on anchors with the provided hover and focus states.

<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>

There are also two special text color cases for use with either light and dark backgrounds. They can handle anchors too. Use .text-dark on lighter backgrounds, and .text-light on darker backgrounds. These will not provide accessible ratios of contrast for all items.

        <div class="text-dark bg-danger">Light text <a href="#" class="text-dark">anchor link</a></div>
        <div class="text-dark bg-gray-100">Dark text <a href="#" class="text-dark">anchor link</a></div>

    </div>
    <div class="col-sm-6">
        <div class="text-light bg-gray-800">Light text <a href="#" class="text-light">anchor link</a></div>
        <div class="text-light bg-gray-900">Light text <a href="#" class="text-light">anchor link</a></div>
        <div class="text-light bg-danger">Light text <a href="#" class="text-light">anchor link</a></div>
        <div class="text-light bg-info">Light text <a href="#" class="text-light">anchor link</a></div>
    </div>
</div>

Backgrounds

Similar to the contextual text color classes, easily set the background color of an element to any contextual class. Anchor components will darken on hover, just like the text classes.

There is also a .bg-transparent for removing the background color for an element.

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

Borders

Borders also be colored with their own set of contextual classes. Borders do not change color on hover state.

There is also a .border-transparent that removes the border color for an element, but keeps the border width in place.

Primary
Secondary
Success
Info
Warning
Danger
<div class="border-primary mb-0_5 p-0_25" style="border: 2px solid;">Primary</div>
<div class="border-secondary mb-0_5 p-0_25" style="border: 2px solid;">Secondary</div>
<div class="border-success mb-0_5 p-0_25" style="border: 2px solid;">Success</div>
<div class="border-info mb-0_5 p-0_25" style="border: 2px solid;">Info</div>
<div class="border-warning mb-0_5 p-0_25" style="border: 2px solid;">Warning</div>
<div class="border-danger mb-0_5 p-0_25" style="border: 2px solid;">Danger</div>

Palette Colors

If the color palette is enabled, any color theme that is added to the $palette-themes Sass map will become available for use. For example a theme named blue, then becomes available as .text-blue-[level] or .bg-blue-[level], where level is in the set defined by the $palette-levels variable.
