Okay... yesterday I tried to make a very small change in my blog template -- I tried to add a bold tag -- and the whole thing hosed up. I managed to out the template back the way it was, but for some reason on 2 out of 3 browsers I viewed the page in, the typeface is suddenly huge. I can't figure out why; the code is identical to previous blog versions. I personally don't like the larger font, but until I can figure it out, I think I'm stuck with it.
If you have a clue what went wrong, please let me know.
