After looking it over, I'm thinking the second example would be a much more simplified method of doing it, which (not understanding javascript very well) hadn't even crossed my mind. All the child divs are wrapped in a parent so that should work.

I'm in the middle of completing another part of the project, but as soon as I have the chance I will try implementing this and report back on the results.

I really have to take a few weeks off and learn some of this stuff.
