I'm doing some research on media queries, and I'm having issue with repeated selectors. They don't seem to have effect if they are already set in a given div ID. What do I mean by that?
Let's say we have a div named "wrapper", its background is set to red, in media query I want it to be blue under specific res, but it has no effect. Color remains red when res changes. I'm beginning to wonder why is that? A tip on how to solve this would be great, thanks in advance!
