You've said everything I wanted to say but I wasn't able to express. CSS is nothing like programming. I am a decent programmer and I can write actual code in virtually any language that's new to me, in minutes. CSS is always tedious and God forbid I don't use it for a couple of months - then I've got to go back and re-learn everything. I'm on my fourth round of re-learning about CSS because I'm not purely a front-end developer.
