CSS & UI Framework
156,356 of the 1,000,000 top sites in our Tranco top-1M census run Bootstrap (15.6%). The long-running responsive CSS framework — still the most common one detected. Detection is homepage-level HTML/header fingerprinting, so a site can run Bootstrap on other pages without it showing here.
