Quick View Font

Why is it so difficult to find css? If I change the font in the standalone, the next time I clear cache it reverts back. I spend most of my time trying to edit css and it's frustrating.

Why would you use #B3B3B3 on a white background? It can't be read but that's what Quick View does.

Can someone please tell me where this font color can be changed? I sure can't find it.
