It sounds like you just haven't put in the effort/time. I very much doubt that CSS is "too hard" for you.

I've had similar experiences with regex, shell, & vim. If you're not doing it all the time, it's easy to just brush it off to the side or google whatever you need to do.

No reason to be an expert in something you're only going to use once in a while.

I would put regex shell and vim all in the same bucket as being esoteric and hard to learn since they don’t replicate any of the normal syntax and patterns you are used to. Actually, they are arguably even weirder than CSS.
