Ah, okay. I thought it might be something similar to how it is with the metadata (where you can use different css for metadata at the beginning of an entry and for metadata at the end of an entry).

I try not to use S2 at this point because I want to make a style completely based on css so people don't have to create a theme layer. I'm taking baby steps here ;-), but when/if I decide to submit one of my styles as an official style, then S2 is definitely the way to go.
