Styling Reference

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

CSS Classes

The Modal component uses these CSS classes (View source styles):

Base Classes

  • .modal__trigger - Trigger element that opens the modal
  • .modal__backdrop - Overlay backdrop behind the modal
  • .modal__container - Positioning wrapper with placement support
  • .modal__dialog - Modal content container
  • .modal__header - Header section for titles and icons
  • .modal__body - Main content area
  • .modal__footer - Footer section for actions
  • .modal__close-trigger - Close button element

Backdrop Variants

  • .modal__backdrop--opaque - Opaque colored backdrop (default)
  • .modal__backdrop--blur - Blurred backdrop with glass effect
  • .modal__backdrop--transparent - Transparent backdrop (no overlay)

Scroll Variants

  • .modal__container--scroll-outside - Enables scrolling the entire modal
  • .modal__dialog--scroll-inside - Constrains modal height for body scrolling
  • .modal__body--scroll-inside - Makes only the body scrollable
  • .modal__body--scroll-outside - Allows full-page scrolling

Interactive States

The component supports these interactive states:

  • Focus: :focus-visible or [data-focus-visible="true"] - Applied to trigger, dialog, and close button
  • Hover: :hover or [data-hovered="true"] - Applied to close button on hover
  • Active: :active or [data-pressed="true"] - Applied to close button when pressed

useOverlayState Hook

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

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

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

Accessibility

Implements WAI-ARIA Dialog pattern:

  • Focus trap: Focus locked within modal
  • Keyboard: ESC closes (when enabled), Tab cycles elements
  • Screen readers: Proper ARIA attributes
  • Scroll lock: Body scroll disabled when open
