ajax search css not validating

hi guys, does anyone know why i get this on the validator:

URI : http://www.insideyork.co.uk/assets/templates/insideyork/insideyorkform.css
108 #ajaxSearch_submit Value Error : cursor hand is not a cursor value : hand
117 #ajaxSearch_output Property -moz-opacity doesn’t exist : 0.95
118 #ajaxSearch_output Property opacity doesn’t exist : 0.95
119 #ajaxSearch_output Parse Error - opacity=95) !important

URI : http://www.insideyork.co.uk/
223 Property opacity doesn’t exist : 0

Because those properties don’t in fact validate, but they make the effects work in a variety of browsers.
