This is far from ideal, and I would personally never use JS for this purpose. As for CSS3 selector support in JQuery, Peter Gasston recently posted an article announcing news that JQuery is losing support for many Level 3 selectors.

@David Smith: If you’re after Level 3 selectors, then you’ll be disappointed with the news that there is no planned implementation of them in the IE8 RC, in case you didn’t already know.

It’s nice to see that a number of vendors are taking the initiative to implement properties included in the Basic UI module, even if they do involve using vendor-specifc prefixes. As I mention in an article I wrote mainly about the box-sizing concept but also go into some detail about the current module status. It is also worth mentioning that on top of having to find a new owner (that’s if Tantek doesn’t want to be reinstated) and a test-suite being created, there are also several features that are at risk of being removed from the module before it exits CR. So in this sense, I would think of the module as being fairly unpolished although it’s been a CR since mid ’04.

(comment mostly just posted to get another browser-involved David on the list)

I didn’t know about Gecko and cursor (or WebKit previous to their ACID 3 work). That is good to know. I’ll add it to the post and look at creating a CSS3 UI compatibility table soon.
