What is Headless UI?
Headless UI components decouple accessibility behaviors (focus management, keyboard shortcuts, ARIA labels) from visual styling.
Why Shadcn UI?
Shadcn UI provides code ownership. Rather than importing opaque component packages from node_modules, Shadcn UI copies accessible Radix Primitives styled with Tailwind CSS directly into your repository.
Summary
Adopting accessible component primitives ensures your web application complies with WCAG standards while maintaining full design flexibility.
