Ok I was hoping this was the answer I have been looking for, but since I looked at the page he posted and still see the 1px gap between containers, I can only assume he either has not tried what you suggested, or it did not work, and since I tried what you suggested from dreamweaver and it did not work for me, I assume this is not the problem. I really need to find an answer for this as it is holding up development of this site. You can have a look at what I am trying to do at

My containers need to stack tightly on top of each other with no gaps, and I have been reading and reading, trying to find the answer, with no luck. If you notice in the bottom right container that contains the feedback module there is NO gap between the bottom of it and the footer, but everywhere else there is.
Any ideas?
