So the #pagewidth div is supposed to form a kind of frame around the #maincontent div. As you can see, I've tried using min-height: 100%, height: 100%, but #pagewidth does not stretch when the content exceeds the capacity of the browser window - it pretty much stops where the window stops.
(I also tried just doing "min-height: 100%; height: auto;" in the #pagewidth div instead of in "html>body #pagewidth". Neither works.)
How can I get that div to stretch to fill 100% of the page?
