Okay I took the suggestion to add the background color to the post and I see where it ends. If you go to the page you can see the green background behind each post..

I got rid of the squiggle gif between the posts and shrunk it down by reducing the post footer padding to 0.
There is still a gap between the posts that seems a bit too large. Actually, it might be good but I still want to find out what controls that gap. The post-info mentioned above does not control that, its the part that is the name of the post.
Any further ideas how to reduce that gap?
