Everything, like, shrunk O__o

[ストロボ・EdGE]

I don't know what I did but yesterday I was responding to a thread and suddenly all of AHS, well, shrunk! Not only the text which is extremely minute, but even all of the graphics on the site. And it's only AHS, not some setting on my computer or browser, so I must have accidentally changed something somehow while responding to a thread. I thought I could just close my browser and open it up again and it'd be fine, or that the next day it'd be back to normal but it's not . And if there's another thread like this, sorry, but I tried searching and couldn't find anything.

Help?
