Oh, got'cha. That's an interesting technique. I'll have to try it and see how it works. Do you which of Trent's posts he mentions it?

If not I can find it, but if you have a link directly to the post it would be appreciated.

From the look of the code I think it's setting the width so it defaults to a relative size of your choosing. The way I'm doing it here you don't have that default. Your default size would either be the max-width if your browser is open larger or the full screen if your browser is open smaller.
