I am trying to achieve a scrolling body with fixed header and fixed sidebar. I think I am almost there except that the body scrolls on top of the header. I wish I could simply increase the z-index of the header in relation to the body but this doesn't work since the header is mostly transparent.
Here is the site: link
Any ideas? Thanks
Edit: I should clarify that I want the content to be invisible as it scrolls underneath the header, not simply as a layer beneath it.
