CSS & UI Framework
137,175 of the 965,200 top sites in our Tranco top-1M census run Bootstrap (14.2%). 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.
