Layers... AGHHHHH!!!

I am not proficient enough with css to troubleshoot your code but looking at your style sheet via the validator, you have some errors. These may be the problem. clip: rect( );

I found this template a while back. Maybe it would be of some use to you in figuring out how to make all columns equal in height.

You could just make the backgrond image of the body look the same as the layers. In this case this would be viable since you are using a fixed width, non centered, layout.

ahhh!! your CSS coding is a mess! lol I didn't bother looking at it. Try cleaning up your CSS so others can look at it

Basically for your three column layout you want it setup like this:

left content
centre content
right content

You have that yes? Right, now, for the left and right DIVs you have them absolutely positioned with the left DIV floated left [this is optional] and the right DIV floated right [not optional, may not work in some browsers if not floated to the right (with a width setting too)] for the left and right divs set absolute widths for those.

For the content div, have that relatively positioned with the left adn right margins set to the width plus padding plus border size.

Well if you didn't get any of that or part of then you might understand if you have a look at the sites I've made, over the last year I have converted all my sites to use CSS Positioning. Here's the link to a table of my sites I have:

I'm currently trying to have all my divs relatively aligned using only floats. This way is much more liquid but it's too hard to explain

Using floats works pretty well, I myself have left off all types of position: absolute, position:relative, etc.
