I get the idea, but don't think that's the case for Tailwind. Tailwind classes map directly to CSS properties, you can't really do much with it if you don't understand CSS
Are you sure? Could it be confirmation bias because you do understand the CSS?
From what I've seen across multiple teams, it's very common for developers to just slap Tailwind onto their project, copy-paste classes they found online and call it "done." Maintainability and reusability are treated as someone else's problem.
