Skeleton
Skeleton is a design system and accessible UI component library built on Tailwind CSS. It provides a collection of pre-built interactive components with built-in accessibility and state management, alongside a CSS custom properties theme engine that enables runtime theme switching and dark mode support.
The project distinguishes itself through its adaptive design system approach, using CSS custom properties to create themeable tokens that integrate directly with Tailwind's utility-first framework. This allows developers to build visual design systems with customizable colors, fonts, and aesthetics, while supporting automatic dark mode detection and on-demand theme toggling without page reloads. The system also includes guides for extending the design system with third-party tools like icons and code blocks.
The library covers common UI patterns including cards, buttons, and tables, rendered with semantic HTML and utility classes. It provides mechanisms for managing interactive state and user input across different frameworks, with built-in accessibility considerations. The documentation includes guidance on applying design systems, switching themes, and integrating cross-framework components.
