MDN does a pretty good job of distilling the web spec into readable documentation: https://developer.mozilla.org/en-US/

I'm in the HTML specs and CSS specs every day :D

- https://html.spec.whatwg.org/multipage/

- https://drafts.csswg.org/

Reading web specs at least once will save you a lot of time. You don’t need to memorize the things, but it helps learning about capabilities that are easy to miss and keywords that’s make searching far more efficient.

I used to read the specs, but I think I gave that up about 15 years ago as no longer practical.

> But I've never met a single person who has ever directly read it.

I love how this is a unit of measure now. "I have never met anyone with an iphone, so...".
