That’s the title of my feature request at Bugzilla. It’s about the content property I wrote about in my previous post.
It turns out it was a duplicate; I searched Bugzilla but I didn’t found anything. Anyway, update your bookmarks to: CSS content
replacement doesn't work with total replacement. I liked my title better…
I made this really easy test case: Content Selector Test, and you know what? Opera applies the rule! Hurray for Opera.
