Hi Jason,
Thanks for the link. I had tried this and other methods, but they didn't seem to work for me. I guess the problem was, that I wanted the shadow to appear around the content wrapper and not just an image or a box.
But I did actually come up with a solution that not only produced a good looking drop shadow, but also grows and shrinks in length with the content wrapper.
Jason, could you open a support ticket, I would like to ask you a question? (not for support)
