For me (maybe) its the size thing. I've never read anything about "content driven size" so maybe I just don't understand it, but I'm often confused about why some box (div) is the size it is. When I use dev tools to try to understand, nothing seems to help. I can see how the rules cascade, I see how the flexbox and grid things work, I can grasp the DOM and selectors - but then why is everything so small or so large... The suggestion of building a page from scratch is good and helpful <BeginHumor>And the next time a CSS friend wants to learn JavaScript I will suggest they start by learning i386 assembly language :-) </EndHumor>
