Webkit Pseudo-Element Selectors (Shadow DOM Elements)

An ongoing project to catalogue all of these sneaky, hidden, bleeding edge selectors as I prepare my JSConf EU 2012 talk.

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:

-webkit-appearance:none;
