Fade on top links

You’d need a graduated image about 1200px wide minimum and about 10px high. The idea would be to use it as a background to the nav container using something like:

#menu {background: url(images/gradient.jpg) repeat-y top left;}

However, the way that your nav menu is currently structured, this would show well beyond the nav buttons – which isn’t what you wanted. In order to get it working properly, you’d need to completely re-structure the menu to allow for this kind of background image.
