I gave a presentation last night on the topic of improving web design for developers. On the topic of CSS I gave a very simple demonstration on using a non-table based layout. It went well over all, but I didn't have a ton of time to get it perfect and resulted with this.

It works, but wasn't the best I could do (the right column noticeably doesn't extend to the bottom of the content). Christian asked a great question about this, but my brain froze and I wasn't able to come up with a quality answer. Of course this one detail plagued me through the night.

Well, the answer is very simple. Wrap the two columns in a container element (another <div> in this case). Set the overflow property to auto or hidden, adjust the width, accounting for padding, and use the same background color as the sidebar. And presto, you get what I meant to do.

If you'd like to see the markup and style, just view the source of the page.
