Convey meaning through color with a handful of color utility classes. Includes support for styling links with hover states, too.
Color
.text-primary
.text-secondary
.text-success
.text-danger
.text-warning
.text-info
.text-light
.text-dark
.text-body
.text-muted
.text-white
.text-black-50
.text-white-50
Contextual text classes also work well on anchors with the provided hover and focus states. Note that the .text-white and .text-muted class has no additional link styling beyond underline.
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.
.bg-primary
.bg-secondary
.bg-success
.bg-danger
.bg-warning
.bg-info
.bg-light
.bg-dark
.bg-white
.bg-transparent
Background gradient
When $enable-gradients is set to true, you’ll be able to use .bg-gradient- utility classes. By default, $enable-gradients is disabled and the example below is intentionally broken. This is done for easier customization from the moment you start using Bootstrap. Learn about our Sass options to enable these classes and more.
.bg-gradient-primary
.bg-gradient-secondary
.bg-gradient-success
.bg-gradient-danger
.bg-gradient-warning
.bg-gradient-info
.bg-gradient-light
.bg-gradient-dark
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.
