Alert is a View on a rounded secondary surface with an optional leading icon, a title and description column, and an optional action pinned to the top-end corner. It is static and stays in the layout; it is not a toast or a modal.

Use the default variant for neutral information, where the icon uses the accent color, and destructive for errors, where the icon uses the danger color.

Usage

import { Alert, AlertTitle, AlertDescription, AlertAction } from "@/components/ui/alert"

<Alert icon={CheckCircleIcon}>
  <AlertTitle>Payment successful</AlertTitle>
  <AlertDescription>
    Your payment of $29.99 has been processed. A receipt has been sent to
    your email.
  </AlertDescription>
</Alert>

Pass a Phosphor icon component to icon, and compose AlertTitle and AlertDescription as children. Any AlertAction child is detected and placed in the corner, and extra end padding is added so the text does not run under it.

Use iconClassName to adjust the icon's size or color.

Examples

Destructive

The destructive variant with a danger-colored icon.

ExtendsReact.ComponentProps<typeof Text>

Accessibility

The container has the alert role.
The icon is decorative; put the meaning in the title or description.

Notes

Uses bg-surface-secondary, text-label, text-accent and text-danger tokens; light and dark follow the system appearance.
The action is positioned with end-4, so it flips in right-to-left layouts.
