Help remove space under post.

I'm having problems with spaces in my blogger template.

Underneath my posts, and underneath my older/newer links, there is empty space which I don't know how to get rid of. I tried so many things, and still no luck. Any suggestions?

P.S. I had greater problems with the permalinks of the entries, such as when I disabled comments, I got a GIANT blank space in that area instead. I removed my permalink links from the titles because I couldn't fix that either.
