If you've given up on learning, naturally your understanding of what problems have been solved (and which remain) is going to be poor.

One of the meta-solutions you've missed is the establishment of "Baseline", which helps web devs understand what features and capabilities are safe to use. I hope this helps! https://web.dev/baseline

Baseline is totally useless, you can have an idea but then still need to go on the detailed browser table to learn more(on mdn). I decided to cherry pick my learning I prefer reading a math book than wasting my time learn by heart what fit-content formula is(total madness):

> Represents the formula max(minimum, min(limit, max-content)), where minimum represents an auto minimum (which is often, but not always, equal to a min-content minimum), and limit is the track sizing function passed as an argument to fit-content(). This is essentially calculated as the smaller of minmax(auto, max-content) and minmax(auto, limit).
