- Present a focused decision that should interrupt the current workflow.
- Use when the interface benefits from a retro, pixel-art visual style.
Examples
Confirm a destructive action
Offer a cancel option alongside a clearly labeled destructive confirmation.
confirm-a-destructive-action.tsx
import { AlertDialog, AlertDialogAction, AlertDialogCancel, AlertDialogContent, AlertDialogDescription, AlertDialogFooter, AlertDialogHeader, AlertDialogTitle, AlertDialogTrigger,} from "@/components/ui/8bit/alert-dialog";export function DeleteProjectDialog() { return ( <AlertDialog> <AlertDialogTrigger>Delete project</AlertDialogTrigger> <AlertDialogContent> <AlertDialogHeader> <AlertDialogTitle>Delete this project?</AlertDialogTitle> <AlertDialogDescription> All project data will be permanently removed. </AlertDialogDescription> </AlertDialogHeader> <AlertDialogFooter> <AlertDialogCancel>Keep project</AlertDialogCancel> <AlertDialogAction>Delete project</AlertDialogAction> </AlertDialogFooter> </AlertDialogContent> </AlertDialog> );}Use normal typography

use-normal-typography.tsx
import { AlertDialog, AlertDialogAction, AlertDialogContent, AlertDialogTitle, AlertDialogTrigger,} from "@/components/ui/8bit/alert-dialog";export function SessionDialog() { return ( <AlertDialog> <AlertDialogTrigger>Continue</AlertDialogTrigger> <AlertDialogContent font="normal"> <AlertDialogTitle>Continue your session?</AlertDialogTitle> <AlertDialogAction>Continue</AlertDialogAction> </AlertDialogContent> </AlertDialog> );}API reference
PropTypeDefaultDescription
AlertDialogReact.ComponentProps<typeof AlertDialogPrimitive.Root> & VariantProps<typeof alertDialogVariants>—Root dialog props from Radix, plus the optional font variant ("normal" or "retro"). The wrapper forwards props to the underlying shadcn AlertDialog; it does not apply font styling itself.
AlertDialogTriggerReact.ComponentProps<typeof AlertDialogPrimitive.Trigger>—Radix trigger props, including className. The wrapper sets asChild to true by default; an explicit asChild prop overrides that default.
AlertDialogPortalReact.ComponentProps<typeof AlertDialogPrimitive.Portal>—Radix portal props, forwarded to the underlying portal.
AlertDialogOverlayReact.ComponentProps<typeof AlertDialogPrimitive.Overlay>—Radix overlay props, including className, forwarded to the underlying overlay.
AlertDialogContentReact.ComponentProps<typeof AlertDialogPrimitive.Content> & VariantProps<typeof alertDialogVariants>—Radix content props plus the optional font variant ("normal" or "retro"). The font defaults to retro behavior: any value other than "normal" adds the retro class. Adds pixel-style border classes, a portal, an overlay, and an aria-hidden decorative border.
AlertDialogHeaderReact.ComponentProps<"div">—Standard div props, including className, forwarded to the shadcn header.
AlertDialogFooterReact.ComponentProps<"div">—Standard div props, including className. Adds flex-col-reverse, sm:flex-row, and gap-4 classes before the supplied className.
AlertDialogTitleReact.ComponentProps<typeof AlertDialogPrimitive.Title>—Radix title props, including className, forwarded to the shadcn title.
AlertDialogDescriptionReact.ComponentProps<typeof AlertDialogPrimitive.Description>—Radix description props, including className, forwarded to the shadcn description.
AlertDialogActionReact.ComponentProps<typeof AlertDialogPrimitive.Action>—Radix action props. Adds pixel-edge decorations and action styling; className is combined with the wrapper's default classes.
AlertDialogCancelReact.ComponentProps<typeof AlertDialogPrimitive.Cancel>—Radix cancel props. Adds pixel-edge decorations and cancel styling; className is combined with the wrapper's default classes.
Accessibility
- Use AlertDialogTitle and AlertDialogDescription to provide the dialog's accessible name and description.
- Keep action and cancel labels clear and meaningful; the decorative border elements on the content are marked aria-hidden.
- The component wraps Radix Alert Dialog primitives, so their dialog interaction and keyboard behavior are inherited.
- The default trigger uses asChild=true; when using it, provide a suitable child element that can receive the trigger behavior.
