Well, it took some work, but we managed to sort out most of the problems with the template that makes Hollywood Gothique look the way it does. Among other things, the homepage slider no longer creates a large white gap between it and the posts displayed below.
On the downside, there still seems to be a problem on pages (not posts) with large images pushing text off the margin, but we are fixing that. Also, the “sticky header” does not work. That is, the horizontal navigation bar at the top (listing the Home button, Departments, Search, etc) is supposed to remain visible no matter how far down you scroll; instead it disappears off the top of the page. We have a support request in to the makers of the template. Hopefully it will be sorted out soon.
