BROWSER & HTML VERSION DIFFERENCES
This page was written for the considerate web page builder.
Using tag elements that are specified in HTML 4.x only may lead to olderbrowsers'
inability to load pages correctly. Though how there can be anyone
still using a browser that does not support at the very least HTML 3.x
is beyond my comprehension.
Anyway, most web pages today are still
built with HTML 3.2 specifications. Additions to HTML 4.0 are not
widely used if at all. Probably because most people do not bother with
it. The exception being <frameset>, but this was already supported
in version 3.2. It was formally adopted in 4.0. This means that Navigator
4.x and Explorer 4.x supports all HTML 4.0 specs and older. 3.x versions
of these two browsers supports HTML 3.2 and older specs.
There are browser spec. expansions.
Some like Netscape include extra tag capabilities.
