I currently have a simple javascript that swaps a small image next to text from a mouseover/mouseout action initiated through an image map. But, it seems that there is probably a better method of doing this with css - perhaps with font weight and color change rather than an image? For example I have a state map with 10 city names on it, and ten companies listed below that just happen to be located in those ten cities. When I hover over the city, I want the applicable company's font to be weighted and change color.
Make sense?
Addition:
I forgot to add - in case in makes a difference. Both the image map and the 'company' list contain alt tags for links.
