The stylesheet switching was really very simple. The one obstacle was the navOver() and navOut() functions. The color selection was hard-coded in the functions and now I needed a way to get the background color from the TopWrapper to use for the mouse over. It should have been simple, but you know
that it wasn't, or I wouldn't be writing about it. I suppose that I should not be surprised that there are still discrepancies in the way that different browsers support document objects, properties, attributes and methods. In any case, I tried using someone else's
do what I want.
