It helped to read that there's a plugin and a module, because at first I had downloaded the plugin and wondered why it didn't work as a module.
Also, the documentation is great! I downloaded the booklet which helped a lot as far as CSS and identifying elements was concerned.
Why the CSS comes in a php file, and why the actual background comes in a repeat pgn is absolutely beyond me. I'm open to education on that one. Once I had that figured out, I was happy!
