Screen shrunk and background grew.

When I logged on 2 days ago  I was surprised to see that the center area of the screen ( where I do stuff on here like Play, Learn, Share Forums, More and down more) grew smaller and the words became hard to read and my backround theme covered most of the webpage. I still have the problem and its really annoying me now, I didnt post this because I though it will go away but now its still here and I dont know how to fix it. Can someone help?

THERE IN THE TOP RIGHT HAND SIDE OF YOUT COMPUTER IS 3 SPOTS WHERE YOU CAN INCREASE DECEASE OR DELETE===TAP THE INCREASE =TO ENLARGE THE SCREEN

Yeah its something you can adjust on your machine.  If what Plavin is saying doesn't work, then try clicking the mouse on a blank area, then typing "CNRTL" and the "-" or the "+" keys to adjust the sizes.

Help. This has happened to me and I can't find the spots as the above poster has suggested. This has only happened on chess.com, other websites are fine.

Any suggestions thanks, this is really annoying.

Try zooming in. What browser/operating system are you using?

Firefox browser and windows 7. It is still the same this morning. Where do I find the zoom?

Sorted it. I was googling around and found the suggestion of ctrl and + and this has now worked.
