Heydon does a very good job of explaining why throwing away the power of selectors makes no sense.
Utility-first detractors complain a lot about how verbose this is and, consequently, how ugly. And it is indeed. But you’d forgive it that if it actually solved a problem, which it doesn’t. It is unequivocally an inferior way of making things which are alike look alike, as you should. It is and can only be useful for reproducing inconsistent design, wherein all those repeated values would instead differ.
He’s also right on the nose in explaining why something as awful at Tailwind could get so popular:
But CSS isn’t new, it’s only good. And in this backwards, bullshit-optimized economy of garbage and nonsense, good isn’t bad enough.
Wrap everything in your CSS reset with a @layer rule.
When you place any styles inside a layer, these styles automatically have lower priority compared to all unlayered styles on the page. Think of it like an !unimportant block. You don’t need to worry about specificity or order of stylesheets at all.
