I agree it's not just React - I think a lot of people simply do not know what CSS can do nowadays.

I do like Tailwind (I guess it fits with how I think). But to make good use of it you _do_ need to know how CSS works (for example, using variant selectors for picking out child elements, using container queries instead of global breakpoints etc).

One addition - I learnt a _lot_ about CSS by reading [Every Layout](https://every-layout.dev/).
