These 2 Column Faux CSS Layouts use a background image to make it look like the
left and right columns are equal in height and independent of each other.
Things couldn't be further from the truth. I created a parent column called faux
and vertically tiled the image, that contained both the left and right child columns.
I then vertically tiled the faux background image and viola.
I first found about this method from the
alistapart site by a guy called Dan Cederholm
