[www-validator-css] <none>

I have a good afternoon with CSS 3.0 features for mozila, chrome and safari, but the fields you see errors, but function normally, how could we do to validate this code.

Of the errors described below:

257 # content. Team. Vcard img Property-moz-box-shadow does not exist: 3px inset # aaa 0 0 0 0 3px inset # aaa
258 # content. Team. Vcard img Property webkit-box-shadow does not exist: 3px 0 0 0 0 3px # aaa # aaa
