Lynx doesn't do JavaScript.  This should be considered a serious shortcoming
in Lynx, but instead it seems to be viewed as a virtue.  I'd really like
to see text browser that did JavaScript and CSS.

Anyway, the answer there would be a <noscript> fallback intended for
browsers which don't do JavaScript or which don't have JavaScript
enabled.

Surely you don't mean "for _anything_".  Do you assume client-side
support for HTML 2.0?  What about HTML 3.2?  What about HTML 4.01
Transitional?  What about HTML 4.01 Strict?  What about CSS level
1?  What about CSS level 2?  What about ECMAScript?  What about
DOM?

See, we need to assume some level of basic support.  Okay, so some
browsers won't measure up to it -- but some browsers (such as Lynx)
have not been reprogrammed in 5 years.  More recent browsers do
indeed have some degree of all of the above, so the answer simply
is to ask what is the reasonable level of support to expect, and
is it fair game to expect someone to be using a reasonable browser
when accessing your site?
