Re: A "Wanna Be" CSS programmer

Here's an example of a browser sniffer that serves up different style sheets
dependeing on browser type and version. This is what I use for my sites:

<.SCRIPT language="JavaScript">
<.!--
var browserName=navigator.appName;
var browserVer=parseInt(navigator.appVersion);
if ((browserName=="Netscape" && browserVer>=6) || (browserName=="Microsoft
Internet Explorer" && browserVer>=4))
  version="n3";
else
  version="n2";

if (version=="n3")
  document.write("<link rel='stylesheet' type='text/css'
href='styles.css'>");
else
  document.write("<link rel='stylesheet' type='text/css'
href='styles_nn.css'>");
//-->
<./SCRIPT>

If you're going to copy and paste this for use, make sure you take out the
periods I put in the script tags and comment tag or it won't work. Also,
make sure you change the name of the style sheets in the document.write
section and name them whatever your stylesheets are named.

HTH,
Lisa
