What problem does it solve? Building accessible, interactive UI components from scratch is error-prone and time-consuming, especially when you need full styling control without fighting pre-styled component libraries. This Skill guides you through creating production-grade design systems with Radix UI's unstyled, WAI-ARIA compliant primitives. ## Core Features & Use Cases - Headless Component Patterns: Implement Dialog, Dropdown Menu, Tabs, Select, Tooltip, and Popover with compound component architecture and full styling control. - Theming Strategies: Apply CSS variables, Tailwind with CVA (class-variance-authority), or Stitches for scalable design system theming. - Accessibility Compliance: Built-in guidance for keyboard navigation, focus management, ARIA attributes, and WCAG 2.1 AA/AAA requirements. - Use Case: You need a custom dropdown menu with checkbox items, radio groups, and nested sub-menus that matches your brand exactly. Use this Skill to compose Radix primitives with your own styles while keeping keyboard navigation and screen reader support intact. ## Quick Start Ask the AI to build an accessible Dialog component with Radix UI primitives styled using Tailwind and CVA variants.
