honestly the best starting point imo is just.. learning the basics first. positioning, selectors, flexbox, grid —that kind of stuff. css isn't something that just clicks instantly, you genuinely have to go through the whole trial and error thing. breaking stuff, not knowing why it broke, googling for 20 mins, THEN it clicks. so don't feel bad if you're a slow learner or your layout keeps exploding lol that's literally just how it goes

once you have the basics down i'd recommend this guide for jai-specific stuff, mdn docs for understanding properties properly, and youtube for visual explanations. also skimming through other people's templates is lowkey also helpful -you pick up a lot just from reading how someone else structured their code

also!! never feel ashamed for using ai to help with your css —there's genuinely nothing wrong with it. even people with years of experience use ai as a tool. it's not cheating or anythin, it's just.. how things are now ^^ I also started out by using ai to help me make my css!
