Unfortunately, the class that is used for those two elements is reused all over the place. There's no way to single out those particular elements without rewriting the HTML, and I got deep into a rabbit hole doing that this afternoon for a much easier change; I'm disinclined to do it again. If I do, it'll be after the simpler CSS changes are done.


I'm still contemplating the separation between posts. The subject line you want to give a different background color, ironically, uses the same class as the elements you wanted a black background for.

The styles they use are overcomplicated in some areas and not complicated enough in others. Go figure.
