Hi ,

While validating my CSS on http://jigsaw.w3.org/css-validator/

I am getting following errors:

1.Property zoom doesn't exist : 1 1.

2.Property -webkit-transition doesn't exist : all 200ms ease-in all 200ms ease-in

3.Property opacity doesn't exist in CSS level 2.1

4.Property -moz-border-radius doesn't exist

5.Property -webkit-border-radius doesn't exist

Is it really required to validate the MarkUp and CSS completely for SEO or these errors which mostly are browser specific can be ignored for now.

If these errors have to removed can someone please suggest the way to do so also.
