What is Semantic UI ?

Concise HTML

Semantic UI treats words and classes as exchangeable concepts. Classes use syntax from natural languages like noun/modifier relationships, word order, and plurality to link concepts intuitively.

Intuitive Javascript

Semantic uses simple phrases called behaviors that trigger functionality. Any arbitrary decision in a component is included as a setting that developers can modify.

Simplified Debugging

Performance logging lets you track down bottlenecks without digging through stack traces.

Unbelievable Theming

Semantic comes equipped with an intuitive inheritance system and high level theming variables that let you have complete design freedom. Develop your UI once, then deploy with the same code everywhere.

Unbelievable Breadth

Definitions aren't limited to just buttons on a page. Semantic's components allow several distinct types of definitions: elements, collections, views, modules and behaviors which cover the gamut of interface design.
