Not wanting to break Yuletide...

...does anyone happen to know if the allowed html mark up includes the ability to centre text?

I'm writing a Yuletide treat which is one of the most fun things ever. Though I really don't know if I can pull it off. It's weird writing for something which was not text-based in the original canon. But I am making extensive use of the online thesaurus and I am giggling a lot.

ETA: I have now uploaded it and it looks fine. Now I have two other stories I want to try and write in the next three and a bit days. One of which really deserves a novel, not a short fic, though that is all it's going to get.
