For what its worth, I had the same experience with Tailwind. I regularly see classes that don't have an meaningful outcome.

I don't think the problem is Tailwind or CSS (well, I guess Tailwind is CSS with extra steps but you get the idea) syntax (or any of the CSS preprocessors), but the fact that styling in browsers has accumulated a lot of cruft, and people who haven't "grown up" with it over the years don't fully understand it (I am more competent than most with it and there's still times I screw up).

One thing that's kinda nice about Tailwind is that it made copy-pasting components easier. So people can get something decent without fully understanding what's happening
