It establishes formal best practices and guidelines for building modern, composable, and accessible UI components for the web, with framework-agnostic principles applicable to React, Vue, Svelte, Angular, and other modern frameworks.

Key Features

• Formal Specification - An open-source standard that establishes clear best practices for building UI components, going beyond informal conventions
• Composable Architecture - Emphasizes composition over inheritance, enabling components to be easily combined to create complex UIs
• Accessibility First - WCAG-compliant with proper ARIA attributes and keyboard navigation built into the specification
• Customizable and Performant - Guidelines for easy theming and styling for any design system while maintaining lightweight footprints with minimal dependencies
• Transparent Code Ownership - Full code visibility and ownership with clear examples and developer-friendly documentation

Who is this for?

This is for frontend developers and UI library maintainers who want to build high-quality, reusable UI components following industry best practices. It is ideal for senior frontend engineers and open-source maintainers who want a formal reference for composable, accessible, and performant component design across any modern web framework.
