Still No Solution if You Can't See the Whole Blog

I tried changing the screen resolution today to see whether the left-side sidebar on the blog would disappear. It was still there. I have no idea why some of you can't see the whole blog page. This blog website is the most simple and standard. I don't know how many blogs are on blogspot, but I'm sure it's in the millions! There's nothing listed on the help pages about this, so it's not a common problem...or maybe I just didn't use the right keywords. Can anyone figure it out?
