Decent > implementation of CSS, of course, took even longer. Today, many browsers have decent implementation of CSS. Only Mozilla (and w3c Amaya) has partial implementation of p-MathML and not of content MathML. Moreover, the CSS spec was BEFORE and MathML WG completely ignored it. > > Perhaps there should have been more awareness of CSS within the > Math group.

I'd challenge even a CSS wiz like George to do that : I understand that Lie said "a markup language that could be presented using existing CSS properties." Not "a markup language that would be restricted to using existing CSS properties." If available CSS properties were not sufficient, then the MathML WG would present us: content MathML + CSS-Math module. Instead they presented us that messy and completely inadequate system called p-MathML that mathematicians and others are masively rejecting. They presented us a MathML system is completely inadequate for the web and would stop from being served on the Internet. What is the point to do exactly the same errors that presentational HTML but powered to the 10 power now? Why <font> was harmfull in HTML and eliminated from specs but lots of inefficient <mstyle> are nice today? Why after of many years, Distler blog is still unable to render something so simple as {ds}^2 (last time i saw it rendered as roman!), why most of people at WHATWG rejected MathML? Why CSS approach can render better the fraction contained in canonical science today that the MathML approach that distort the spacing for numerator? Why... I believe that the real problem then was that the MathML WG thought that CSS was not winner, ignored lesson from the ISO 12083 + DSSSL world and decided reinvent the wheel. Somewhat as today we see MathML folks claiming that a CSS approach _cannot_ render matrices, when just ***can*** (and surprise when can a CSS approach to that!) and with a bit of work and better CSS implementations CSS can render matrices better than p-MathML can.
