Alert

Edit this page Leave feedback

The Alert component displays a short, important message in a way that attracts the user's attention. Alerts offer four severity levels that set a distinctive icon and color:

Info: used to convey general information or actions that aren't critical, note that info variant should not contain any icons in it
Warning: used to display information that needs attention
Success: used for success messages
Danger: used to communicate problems that have to be resolved immediately

This component utilizes and extends the Alert component from react-bootstrap.
See React-Bootstrap for additional documentation.

With Action Buttons

The Alert component supports a dismissible button and a custom call-to-action button, via the dismissible and button props respectively. The buttons may be right aligned or stacked. On extra small screen widths, the buttons will be stacked.

The stacked variant should be used for:

Placement in sidebars or small container
Extra-small breakpoint and below
