CSS & UI Framework
3,915 of the 1,000,000 top sites in our Tranco top-1M census run Foundation (0.4%). A responsive front-end CSS framework providing a grid system and prebuilt UI components. Detection is homepage-level HTML/header fingerprinting, so a site can run Foundation on other pages without it showing here.
