CSS: can't give divs to extend to bottom of it's containing div

I'm having trouble with div height. I have a three column layout and an overall 'main' div they are in. Each div has a border around it. I can't get the enclosed divs to extend all the way down and end evenly.

Please see this example: http://www.sure-start.com/sample.html 

and if you can help, please view source code (the css is on the page) and let me know what I can do.

I have looked this up online and have tried 'height:100%' to html, body, main, and the divs in question. It didn't seem to help.

Appreciate any assistance!
