Core Capabilities of HeroUI
Theming System
Provides a Tailwind CSS plugin that supports modifying the semantic tokens of the default theme (such as colors and backgrounds) or creating entirely new themes. Sample code demonstrates the primary color configuration for different themes (e.g., primary: "#0072f5").
Supports automatic light/dark mode switching by detecting the dark attribute on the HTML element. Simply add the attribute to the root tag to enable the default dark theme.
Performance
Built on Tailwind CSS with no runtime styles. Unused classes are purged during bundling, ensuring a lightweight and fast experience.
Fully typed API (TypeScript support), lowering the learning curve and supporting React Server Components (components include the "use client" directive and can be used directly in RSC).
Multi-package architecture allows developers to install components on demand, reducing redundant dependencies.
Accessibility
Built on React Aria and compliant with WAI-ARIA standards. Includes built-in keyboard navigation, focus management, and screen reader support. The focus ring only appears during keyboard or screen reader navigation.
Component Customization Capabilities
Built on Tailwind Variants, supporting slot-based customization of component styles to avoid class conflicts. Sample code demonstrates custom button style configuration (such as hover animations and shadow effects).
Components support ** polymorphic as prop**, allowing the underlying element tag to be overridden (e.g., rendering a button as a link).
