Right now my sidebar is as long as the content inside it. But I want it to be the same height as the post or page (which of course varies in height according to it's own content).
Take a look at this website: http://www.spike.com/
I know they don't use WordPress, but look at their sidebar and how it stretches all the way down to match the height of the page.
How can I achieve the same?
BTW I don't want to use the "min-height" css property.
