Have a looksee here: http://glaanieboy.dyndns.org/develop/ This is a new development version of my new website, so don't complain about how it looks. I have one big table, spreading across the entire page, which is divided into three columns, the left one being navigation and stuff, middle one is news and announcements and the right one will fit my shoutbox. As you also may see, the table stretches out over the entire width, but not the entire height. I use CSS, so I added height: 100% to class tablemain, but that didn't help. Same thing goes for adding height="100%" directly to the <table> tag of the main table. The only thing that makes it stretch out to the full height, is hardcoding the height in pixels, but I don't want that, for compatibility reasons in other resolutions. How can I make it dynamically stretch out over the entire height of the page?
