## Props

| Prop | Type | Default | Description |
| --- | --- | --- | --- |
| variant (Alert) | `"default" | "destructive"` | `"default"` | Color treatment: neutral card surface or destructive border and text. |
| alertVariants | `(props?: { variant?: "default" | "destructive" | null } & { class?: ClassValue }) => string` | — | Exported class-variance-authority helper that composes the alert class names. |
| className (Alert, AlertTitle, AlertDescription, AlertAction) | `string` | — | Additional classes merged onto the part that receives it. |
| children (Alert, AlertTitle, AlertDescription, AlertAction) | `React.ReactNode` | — | Title, description, and action content; an optional icon as the first child switches the layout to an icon column. |
| ...props (Alert, AlertTitle, AlertDescription, AlertAction) | `React.ComponentProps<"div">` | — | All remaining native div attributes are forwarded to the part that receives them. |
