After about a ~decade with atomic CSS frameworks (BuzzFeed Solid, Basscss, and then finally Tailwind), I think I'm convinced now that Stylex is superior for agents. Stylex constraints lead to greater consistency and correctness as your codebase grows. I do still think Tailwind is the ideal human DSL for styling, but in a world where I'm barely touching CSS/class names by hand, the tradeoffs have changed. Again, if I were still hand writing code, Tailwind still wins, but we're not doing that anymore.
