Semantic UI is a front‑end development framework that bridges the gap between designers and developers. It provides a comprehensive collection of responsive UI components—buttons, forms, menus, grids, and more—styled with intuitive, English‑like class names. The library includes theming support, customizable variables, and integrations with popular JavaScript libraries, enabling rapid prototyping and consistent, accessible interfaces across web projects.
