After the success of the State of JavaScript survey Raphaël Benitte and Sacha Grief have decided to take on the CSS world! CSS has been around for a while but lately it's seen a lot of really big evolutions, both in the language itself (CSS Grid, Flexbox…) and the ecosystem (CSS-in-JS). And there's also the whole "great front-end divide" issue… So hopefully this survey will help developers everywhere identify the latest trends and make decisions on what to learn next.
