Wow... you would expect CSS-rewriting to do as much as taking a second argument (in the syntax you mention) and putting it in index, say... and does this seem in reach, css-ers ? (of course, removing the brackets, ....). > And of course, while we are waiting for the ability to re-structure > trees, we still have the choice to do that restructuring server side > using XSLT or the like... Oh sure. And we're doing this in ActiveMath for example... This was the part of my mail saying that some DHTML would sort of allow us to reach great heights (with some, sadly, very special browsers, I fear). We're doing it in HTML 4 presentation-target for example. And it allows the sub-term under the mouse to be highlighted (the subterm of the content tree)... but that's all "added" by the XSLT and the markup becomes very heavy... It works in HTML-4, and could work in XHTML+MathML on Mozilla. But for it to work in MathPlayer we would need the latter to run some javascript, and DOM, and... is it really wished ? It looks cleaner to be able to associate the semantic of something under the mouse from the markup synchronized than with some onMouseOvers, or ? paul
