Participate to the CSS survey 2019
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.
