Hi! It's no bother at all, and I'll be glad to help you if I can. (Sorry about the delay, holiday weekend and internet issues.)

Are you looking to make elements of your layout have the hover change, or do this in actual entries? I don't think it's going to be possible with inline styles per entry (IJ won't let you put a stylesheet at the top of an actual entry), but there may be a way to make it work similarly - if not exactly - to the code on that site if it's just within the layout.
