What the????

Ashton was playing with my computer and did something to my blog!!! Whenever I go to look at my blog, the background is scrunched up into a smaller rectangle and I can see a blank, white background surrounding it, am I the only one seeing this? Maybe it's my computer? WEird!!!! I have re-done the html like 10 times and I am still having these problems, maybe someone out there knows what to do for it....Let me know if you do!!!
