First time I got a CSS thing to actually look right, felt like magic
I was messing with a personal project page in my browser, trying to get a navigation bar to sit perfectly at the top with a shadow underneath. After three hours of Googling and tweaking margins, it finally snapped into place on my screen. Does that moment ever get old, or do you still get a little buzz from it?
Read somewhere that even experienced developers still chase that feeling of getting CSS to behave. That moment when you finally understand why your flexbox wasn't working is genuinely satisfying. Still gives me a little buzz every time it clicks into place.
