Colors

Colorize text with color utilities. If you want to colorize links, you can use the .link-* helper classes which have :hover and :focus states.

.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


Background colors

Similar to the contextual text color classes, set the background of an element to any contextual class. Background utilities do not set color, so in some cases you’ll want to use .text-* color utilities.

.bg-primary
.bg-secondary
.bg-success
.bg-danger
.bg-warning
.bg-info
.bg-light
.bg-dark
.bg-body
.bg-white
.bg-transparent

Button

Bootstrap includes several predefined button styles, each serving its own semantic purpose, with a few extras thrown in for more control.


Alerts

Alerts are available for any length of text, as well as an optional close button. For proper styling, use one of the eight required contextual classes (e.g., .alert-success). For inline dismissal, use the alerts JavaScript plugin.


Tables variants

Use contextual classes to color tables, table rows or individual cells.
