I'm very, very good at CSS and this is absolutely maddening. I grudgingly respect it a lot more because it's really fuckin tough LOL. No overwrites, no transforms, locked elements you can't manipulate, limited amount of CSS property "slots" you're allowed per puzzle. In the age of AI where answers are immediate, hats off to something this absolutely infuriating hahaha
at the second puzzle I went all cocky with a transform and the pop up message telling me I couldn't use it really got me hooked - now, this is a challenge
