Karl, I think I have finally snapped to what you advised. You said:
You're fighting against two principles: event bubbling and style cascading. You can limit the event to be triggered only on those top- level items, but if you're directly applying a style to those top- level items, the child elements are also going to receive the styles because of the cascade, unless their styles are explicitly set to something different. So, I have to limit trigger to event.target PLUS I need to make sure that each of my bottom elements do not inherit styles? Now, I will work on this principle. I suppose that means that I need to counter every style attribute I give to the highlight,plus every style of every parent or ascendant above.
