[Zope3-dev] replacing acronyms for tooltips

[Garrett Smith]

I'd like to replace the existing 'tooltip' implementation in widgets, 
which uses the 'acronym' tag.

Acronyms really aren't appropriate here and are not widely supported by 
browsers. There's a note to replace the acronym with DHTML/JavaScript.

I've done a quick survey of DHTML/JavaScript tooltip implementations and 
haven't seen one that works perfectly -- each has some drawbacks when 
used on various browser (some hand waving here). In addition, the 
DHTML/JavaScript approach requires a sizable JavaScript file download 
(10-15K) to get the functionality. And there's the matter of what 
license the tooltip code is available under.

Until we can find or develop a sufficiently robust tooltip 
implementation, I propose that we use the 'title' attribute of 
span/div/a tags whenever we want to display a tooltip. While 'title' 
isn't perfect either, it seems to be an emerging standard for tooltips 
and doesn't require JavaScript. In any case, I think it's preferable to 
acronym.

Are there any objections to replacing the use of 'acronym' with the 
'title' attribute in span/div/a tags to display tooltips?
