M$ Internet Explorer Sux

I have a bit of a problem here. I’m doing a site…ok making my blog again. I will attach the images to show the problem.

ie.gif = internet explorer
ff.gif = firefox

Firefox is the best. Lol I hate IE even more now. Can anyone help.

And the main content bit where it disappears is called blog (#blog)
