There turns out to be a valid way of hiding style rules from Internet Explorer 4 for Windows. I just tested it myself last night as I installed Windows 98 for the umpth time. You just write:@import "filepath/filename.css";
as opposed to @import url("filepath/filename.css");
The only problem is it shuts out Konqueror 2.1.2 as well but, I imagine later versions of Konqueror will fix this and, as I’ve reiterated many times, the site is still readable and functional without the style, it just looks bland.
Anyway I intend to implement this on all my sites.
