The HTTP Archive finalized the Web Almanac 2020, an annual report on the state of the web. The report gathers its conclusions in 22 chapters organized in four sections (e.g, page content, user experience, content publishing and distribution): jQuery is still 80% of the web; CSS Houdini is seldom used; the median website ships 400 KB of JavaScript in 2020, 14% more than in 2019; and many more.
