As far as I know there's no solution to your problem using CSS. All of 
the properties you're using are part of the CSS2 specification, for 
which there is no support below NN 5.0.

> This seems like a rather elementary problem, perhaps it's just my 
version of netscape (4.7). But i'm just trying to add background image 
to the body tag using a style sheet.  This works just fine in IE, but the 
darn thing won't display in Netscape!! Does any one know any savy 
tricks around this crule game known as netscape?

>     BACKGROUND-IMAGE: url("images/Nav/watermark.jpg");
>     BACKGROUND-POSITION: right top;
>     BACKGROUND-REPEAT: no-repeat
