The demo (http://webdesignerwall.com/demo/css-social-buttons/ http://webdesignerwall.com/demo/css-social-buttons/) looks great but a button is pretty useless without an :active (pressed) state. Would be nice if it was built-in. There are some pressed classes defined but I don't think you can dynamically add them when the button is :active through CSS only.
