CSS good but LEGIJA top 1
At work we use bulma.css, at most places they use bootstrap.
So no, professionally, nobody pays for a CSS-guru any more, they all have become cheap and just use a framework.
So my pro tip (I've been doing this shit for 15 years) is to just learn the basics, and then get really famililar with a CSS framework instead as that's what you'll end up doing in anyways :P
I'd recommend you to focus all in on JS instead, get your fundamentals right, then start dabbing with the two big frameworks, React & Vue
And use bootstrap or bulma together with it
Hack together some smaller apps (todo app or similar), commit to github and you'll get hired in no time :-D
I'd go for Vue.js + Bulma.css, but every developer has their own taste :-D
You need to know it, but bootstrap is just better. If you think it's any gamechanger - you may want start thinking about some other languages.
Also - don't fight it, if you want to be programmer just use Java or C++. Using popular lang is nothing wrong.
Counter strike source is important!!!!!
Computer programming? More like puzzle solving. That shits no joke
