I really messed up this time.

I was trying to alter the Home Page of a site I was working on to make a certain area shorter. I used the Custom CSS plugin for way too many things trying to make it happen, and now when I view the site I get about four or five different Home Page layouts every time I refresh the page, how in the world do I fix this one?
