Just as an experiment I’m trying to use javascript to detect Mozilla(Netscape)-based browsers and serve up their own stylesheet. Here’s what I’m using to catch the broadest range of these browsers.
//detect Netscape 4.7+
if (navigator.appName==“Netscape”&&parseFloat(navigator.appVersion)>=4.7)
Assuming the js is correct how and where do I reference the stylesheet after detection? Would it be structured in a similar fashion to a conditional comment?

You would write a reference to it using document.write, if you’re
inside the JavaScript domain. If you are doing this in PHP, then
simply echo out the link that way.
//JavaScript
if (navigator.appName == "Netscape" && parseFloat
(navigator.appVersion) >= 4.7){
document.write(‘’);
}

Thanks. I hadn’t considered PHP, I wonder if that would be
preferable. I’ll have to research that.

PHP browser detection is very crude compared to JavaScript. There are numerous wrappers out there, but they amount to endless regular expressions applied to whatever the browser (and/or any intermediate cache servers) sends as its “user agent” string; where JavaScript just “asks” the browser and gets a nice clean array of properties.
