Not sure what point you are making here, but one of the nice things about modern browsers is you can write CSS and see the page update in real time. This is likely where a lot of OPs code came from, that might look confusing if you take it at face value only.

Whenever I'm faced with a CSS problem, it's usually just a case of toggling on/off CSS in the DevTools to find the offender.

lucky you, whenever I face a css problem, it's usually the Safari/iOS engine doing something stupid with the browser chroma and requiring dozen hops to work around.
