I have been using CSS since, well, they were invented back in 1995 but not continuously (when I need them). And I can never remember how to properly center things or how to do a lot of supposedly simple things. The specs has a lot of confusing naming (the naming have some logic, but nevertheless a confusing) and of course a lot of interrelated effects.

We used to have css editors that helped.

But I’m glad LLMs can now write CSS for me, and it nearly works perfect every time (I sometimes have to dig and fix things, and to push it to use the latest specs not old obsolete tricks)
