An Example:
Here is an HTML example I have created: http://jsfiddle.net/Tgjnp/2/
The Question:
The CSS:
a {
    color: #bbb;
    text-decoration: none;
    margin-right: 2em;
    font-weight: bold;            
}
.green {
    color: green;                        
}
By the example, the set class is to get the fade animation, so the specified color fades in and out on mouse hover. Other than that, it should revert back to its default color.
The question is, how to have the hover color fade in and out?
