A super-simple way of making Netscape 4.x-specific stylesheets

Just make sure that the style settings in ns4.css are overriden than the settings in gecko.css.

<html>
<head>
  <title>ns4-specific css</title>
  <link type="text/css" rel="stylesheet" href="ns4.css">
  <style type="text/css">
    @import url("gecko.css");
  </style>
</head>
<body>
  <p>Isn't it ?</p>
</body>
</html>
