Like, I know Python 3.6 and it gives me a general knowledge of Python 2.X but obviously there are differences. Same with CSS, do I go study basic CSS or go for CSS3 ?
I don't have a current use case/purpose to study either except that I want to learn it. Ideally, I'd learn enough to (way down the line) net me a remote working job, but that's a far flung hope and I mostly just want to learn to learn. Sorry if this has been asked a ton, tried to find it but didn't see anything.
