Alternative style sheets

I've had a site using alternative style sheets for a good year now. It was developed using Firefox 2 and it works in IE7 and Safari 3.1 and Opera 9. How is this a new feature? --rtlong 00:13, 15 April 2008 (PDT)

It's not. Just recently documented. --Sheppy 07:41, 15 April 2008 (PDT)

Alright, thanks. That makes sense. --rtlong 10:22, 15 April 2008 (PDT)

As it is linked to from Firefox 3 for developers, shouldn't this page also mention the CSSOM API which was supposedly added in Firefox 3? -- BenoitL 07:44, 20 April 2008 (PDT)

That's news to me. I'll look into it, thanks. --Sheppy 11:05, 20 April 2008 (PDT)

The files that make up the CSSOM support look like they were checked in four years ago. How sure are you that this is new in Firefox 3? --Sheppy 08:07, 22 April 2008 (PDT)
