Lynx is a browser. Lynx does not support JavaScript.

Why? CSS is supposed to be an optional presentation layer. User  
agents shouldn't need to download it at all.

You still haven't provided any examples.

Currently, a well written document will have one place to look for  
semantics (the HTML document) and one place to look for presentation  
(the stylesheet). Your proposal would put semantics in the stylesheet  
as well as the markup.

I said "information", not "content". This would include expansions of  
acronyms, URIs that are being linked to, and the language the  
document is written in (to give a few examples).
