If you stick to the W3C DOM then your scripts will be executable by
IE5+, Netscape 6+ and any other up-to-date browsers (Safari, Phoenix,

For the visual layout, yes. For the scripting, it uses the DOM. To stop
older browsers choking on it, I simply included a test for DOM
compliance with this little wrapper:
that are smart enough to understand it pass the test. Older browsers
just carry on, blissfully unaware, without any error messages.
sniff for specific browsers. It'll only end in tears. Sniff for what
you want to support instead.
So if, for example, you had temporarily lost your mind and you wanted
to build a site that only worked in using Netscape 4's proprietary
Document Object Model, instead of sniffing the browser agent and
version number, you would just check to see if document.layers exists.
By the way, something that hasn't come up in this discussion (and
probably doesn't need mentioning because I'm sure most people know this
already) is that Netscape 6 has nothing to do with Netscape 4. Zilch.
...okay the name is similar, but apart from that it's a completely
different beast with a completely different rendering engine and
Document Object Model. Netscape 6 doesn't include backwards
compatibility for Netscape 4's proprietary Document Object Model.
In a nutshell; even Netscape don't support Netscape 4!
