      <AlertDialog.Backdrop className="bg-red-950/90">
        <AlertDialog.Container className="items-start pt-20">

            <AlertDialog.CloseTrigger />
            <AlertDialog.Header>
              <AlertDialog.Icon status="danger" />

              <p>This alert dialog has custom styling applied via Tailwind classes</p>
            </AlertDialog.Body>
            <AlertDialog.Footer>
              <Button slot="close" variant="tertiary">
                Cancel
              </Button>
              <Button slot="close" variant="danger">
                Delete
              </Button>
            </AlertDialog.Footer>
          </AlertDialog.Dialog>
        </AlertDialog.Container>
      </AlertDialog.Backdrop>
    </AlertDialog>
  );
}

Customizing the component classes

To customize the AlertDialog component classes, you can use the @layer components directive.

Learn more.

@layer components {
  .alert-dialog__backdrop {
    @apply bg-gradient-to-br from-black/60 to-black/80;
  }

  .alert-dialog__dialog {
    @apply rounded-2xl border border-red-500/20 shadow-2xl;
  }

  .alert-dialog__header {
    @apply gap-4;
  }

  .alert-dialog__icon {
    @apply size-16;
  }

  .alert-dialog__close-trigger {
    @apply rounded-full bg-white/10 hover:bg-white/20;
  }
}

HeroUI follows the BEM methodology to ensure component variants and states are reusable and easy to customize.

useOverlayState Hook

import {useOverlayState} from "@heroui/react";

const state = useOverlayState({
  defaultOpen: false,
  onOpenChange: (isOpen) => console.log(isOpen),
});

state.isOpen; // Current state
state.open(); // Open dialog
state.close(); // Close dialog
state.toggle(); // Toggle state
state.setOpen(); // Set state directly

Accessibility

Implements WAI-ARIA AlertDialog pattern:

• Focus trap: Focus locked within alert dialog
• Keyboard: ESC closes (when enabled), Tab cycles elements
• Screen readers: Proper ARIA attributes with role="alertdialog"
• Scroll lock: Body scroll disabled when open
• Required action: Defaults to requiring explicit user action (no backdrop/ESC dismiss)
