I am working on a skin for DotNetNuke and I am having a problem with setting the height to 100% of one of my Divs. I have done some research and I understand the parent Div needs a height for my sub Div to be set to 100%, however my parent Div is set to 100% and then the body Div is set to 100% and this is still not working. My boss hasn't given me much time on this project and I really need help ... gotta love how people that don't understand IT work set the deadlines. Attached is my code. What I am trying to do is simply have one main Div in the center of the browser window and 2 divs, one on either side that has a gradient to help the box stand out more. Any thoughts or help would TOTALLY be appreciated!
