Hi Folks,
I have stumbled over this website
<http://www.westciv.com/style_master/academy/css_tutorial/index.html>
and I wonder how they manage to invert the colors of the fixed
background image when scrolling downward and the blue header moves
away. I do not find any directive of the header beckground which tells
to invert the underlying bg image.
Any hints?
Thank in advance - Dudelman.
