# Radix UI Design System Build production-ready, accessible design systems using Radix UI primitives with full customization control and zero style opinions. ## Overview Radix UI provides unstyled, accessible components (primitives) that you can customize to match any design system. This skill guides you through building scalable component libraries with Radix UI, focusing on accessibility-first design, theming architecture, and composable patterns. **Key Strengths:** - **Headless by design**: Full styling control without fighting defaults - **Accessibility built-in**: WAI-ARIA compliant, keyboard navigation, screen reader support - **Composable primitives**: Build complex components from simple building blocks - **Framework agnostic**: Works with React, but styles work anywhere ## When to Use This Skill - Creating a custom design system from scratch - Building accessible UI component libraries - Implementing complex interactive components (Dialog, Dropdown, Tabs, etc.) - Migrating from styled component libraries to unstyled primitives - Setting up theming systems with CSS variables or Tailwind - Need full control over component behavior and styling - Building applications requiring WCAG 2.1 AA/AAA compliance ## Do not use this skill when - You need pre-styled components out of the box (use shadcn/ui, Mantine, etc.) - Building simple static pages without interactivity - The project doesn't use React 16.8+ (Radix requires hooks) - You need components for frameworks oth...
