Change navigation font color based on background

Question

My problem is this. I have a fixed left navigation bar and I have to change the list font color based on the background of the section under it. The code is like this fiddle. So

Answer 1

Can't you just give it a neutral colour to the fixed div and make it wrap around its content rather than have to resort to client scripts to dynamically change the colour? I have sanitized a bit the fixed element to make it look a bit more appealing...padding, margins, etc.

#left_side
{
    position:fixed;
    left: 20px;
    top:10px;
    z-index:999;
    background-color:#eee;
    padding:10px;
}
