I'm learning pretty fast, and I can feel that very soon I'm going to "get" a lot of things I should already be getting. But right now I still don't. So please indulge me with a few silly questions here...
I already knew that if this was possible it would involve CSS. I've gotten pretty good at editing CSS files, figuring out what the code applies to and making changes. I can also add *new* CSS to the inserts filed in the theme options. The thing is, though, I have no idea what new code to add if it involves complicated things like functions (which I'm imagining this utilizes).
So I'm not sure what you mean by "the category should be in the post classes?"
And more basically, are you suggesting I add new CSS code to the inserts field in the theme options? Or modify some css code in some file somewhere? If the former, how do I find out what code to use? I know basic css, like { color:#123456; } but assigning this color to just the title text of a particular category... no clue.
Am I asking too much? I know this forum isn't a basic css instruction forum. But I *do* feel on the verge of a big leap of understanding where then I won't need to ask so many questions.
