CSS & UI Framework
452 of the 1,000,000 top sites in our Tranco top-1M census run Semantic UI (0%). A CSS and JavaScript UI framework offering pre-built, human-readable component classes for building interfaces. Detection is homepage-level HTML/header fingerprinting, so a site can run Semantic UI on other pages without it showing here.
