I'd disagree. There is a lot of new stuff to CSS making our lives HUGELY easier. Classic example is CSS grids that is only recently starting to become ubiquitous in commonly used browsers, and the new units of measurement that go along with it like 'fr'. CSs does not feel stagnant to me, but is evolving I think... Perhaps not at the breakneck speed that JS libraries are, but then the core of ECMAScript is not going as fast as JS libraries either.
