An ongoing project to catalogue all of these sneaky, hidden, bleeding edge selectors as I prepare my JSConf EU 2012 talk. I'm in the WebKit source so you don't have to be! 

Everything is broken up by tag, but within each the selectors aren't particularly ordered. 

I have not tested/verified all of these. Have I missed some or got it wrong? Let me know. - A

A friendly reminder that you may need to set this property on your target/selected element to get the styling results you want:
