I would like to use a custom background image, and am wondering if it is possible to have it slowly scroll sideways.

Are there CSS (or even JS) controls that allow for this? Is an animated GIF the way to go?

And what are the CSS selectors for Theme Designer elements? I'd like to test this out on my user-level CSS page prior to making it live for the whole wiki.
