Semantic UI
Semantic UI is a development framework designed to help developers create beautiful, responsive layouts using human-friendly HTML. By treating words and classes as exchangeable concepts, it utilizes syntax from natural languages such as noun and modifier relationships. It features intuitive JavaScript behaviors, simplified debugging with performance logging, deep theming variables, and over 50 UI components.
