Semantic UI

UI is the vocabulary of the web.

Semantic empowers designers and developers by creating a language for sharing UI. Lose the Hieroglyphics: Semantic is structured around natural language conventions to make development more intuitive. Have a conversation with your components: Semantic gives you a variety of UI components with real-time debug output, letting your code tell you what its doing.
