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