In this demo only the links with the attribute 'class="fadeLink"' are faded.
In this way you can make it so that just the links in a navigation menu are the ones that fade.
Run your mouse over the fading links to the left and the non fading links below.
The next step is to have different fade in colors depending on the attributes of the class. (Still working on that one).

NOTE: The links below have their own, seperate a:hover (mouseover) effect.
