JavaScript Library & Framework
26,986 of the 1,000,000 top sites in our Tranco top-1M census run Modernizr (2.7%). A JavaScript library that detects which HTML5/CSS3 features a browser supports, enabling progressive enhancement. Detection is homepage-level HTML/header fingerprinting, so a site can run Modernizr on other pages without it showing here.
