With a little JavaScript, it's not hard to make DHTML which works in
all DHTML-browsers.

E.g. you have this layer:

<style type="text/css">
#mylayer {
         position: absolute;
         top: 300px;
         left: 30px;
         background-color: orange;
}
</style>

<div id="mylayer">
Text in a layer.
</div>

Just add this JavaScript function:

<script language="JavaScript">
function getStyle( layer ) {
         if( document.getElementById ) {
                 return document.getElementById( layer ).style
         } else if( document.all ) {
                 return document.all[layer].style
         } else {
                 return document[layer]
         }
}
</script>

And in JavaScript, you can change all kinds of properties:
getStyle('mylayer').left = 120
getStyle('mylayer').top = 100
getStyle('mylayer').visibility='hidden'
getStyle('mylayer').visibility='visible'
getStyle('mylayer').zIndex = 2

This works in Netscape Navigator 4 and higher and Internet Explorer 4 and 
higher!

With a little JavaScript you can also make cross-browser clipping and
content-changing. (And that's about it for cross-browser possibilities).

And I never noticed Netscape 6 being slower than other browsers.

There is no excuse not supporting the W3C standards!
