REQ: Help with color inversion of background image...

[dudelman]

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.

body {font-size: 100%;
font-family: Verdana, Helvetica, Arial, sans-serif;
margin: 0;
padding: 0;
background-color: #fff;
background-image: url(images/page_bg.gif);
^^^^^^^^^^^^^^^ ^^^
background-repeat: no-repeat;
background-attachment: fixed;

}
#header {background-color: #091c5a;
background-image: url(images/banner.gif);
^^^^^^^^^^^^^^^ ^^
background-repeat: no-repeat;
background-attachment: fixed; }
