Q: jQuery datepicker css validation to W3C standards I am trying to get the W3C Validator working for all my XHTML and CSS.  However, when using the standard jQuery datepicker, I get 23 CSS validation errors in the jquery-ui-1.8.23.custom.css file that came with the download.
I really don't want to have to change my footer (or add a non-standard footer) to remove the CSS validation icon, but I also don't want to customize the CSS file to eliminate these errors either.  Are these the only two options I have?

A: For zoom property - its a fix for IE. Commonly used by jQuery or Google. So if the zoom is your only bug - dont bother with it :) 

A: Don't be overzealous with the validator. It only provides you with quick overview of the potential problems you may have. Having browsers' prefixes on your CSS doesn't affect your page loading or browser performance by any mean. It won't rank your site higher if your CSS pass all the rules. Today front-end development is in continuous change. Drafts are changing everyday and new features are experimented. If you want your CSS 100% to be valid then remove all the prefixed rules ... It comes with a price though.
