Aspects of modern HTML/CSS you may not be familiar with

I really do appreciate the nesting they've added but looking at it as a whole, CSS is a really strange and in my humble opinion, a terrible language. Perhaps I'm just holding it wrong, but it's just so complicated and messy, it sometimes feels like you're just arranging arcane runes in different ways until you make it sort of work for you. It's both a system for styling text based on inheritance, and a layout system for block and inline elements, nested recursively but without inheritance, only containment. I think it was a mistake to combine styling and layout, and I don't feel like adding more and more capabilities to something fundamentally broken can fix it.

“I believe a lot of the negativity towards CSS stems from not really knowing how to use it. Many developers kind of just skip learning the CSS fundamentals in favor of the more interesting Java- and TypeScript, and then go on to complain about a styling language they don’t understand.”

from the article is talking about people like you, who refuse to learn something properly but have the arrogance to think they know better.

I don't have the time to spend weeks for every little tool to study its details and edge cases, I simply want to use them and get stuff done. If a tool is actively counterintuitive and hostile to its user, then it is flawed and it is no wonder users will seek out alternatives.
