Issue: Big texts and signature issues?

Is it just me, or when I visit here, the texts are a bit bigger than what it used to be (yesterday I do recall the texts were not this big), and it broke my signature formatting in any of my posts as well.

I'm wondering what happened. Oh, and I was using Color Flattered X atm.

Oh, I guess it makes sense a bit. It's weird that the sig in my profile page is not affected, though. Thanks for the explanation, Hiroshi.
