Can someone tell me how to specify a CSS3 file for validation by the W3C?
In HTML5, we use <!DOCTYPE html>, but what should we use in a CSS file?
Whenever I try to validate my CSS file containing CSS3 elements like @font-face and box-shadow, it shows errors because it doesn't recognize them as CSS3. Is there a solution for this?
Thank you in advance. - Davide.
CSS files do not have a built-in identification feature. To verify a file against a specific version of CSS, you must manually select the desired version. This can be done in the W3C Validator by choosing from the "Profile" menu under "More options."
Although CSS Level 3 is available, it's difficult to determine its full significance until all CSS3 Modules are finalized (which may take some time).
Bob's code failed because he forgot to use code tags, but here is the actual code snippet:
http://jigsaw.w3.org/css-validator/validator?profile=css3&usermedium=all&warning=1&vextwarning=&lang=en&uri=http%3A%2F%2Fwww.yourwebsitename.com%2F
Unfortunately, using this will cause issues with W3C Markup Validation.

I find it amusing that code from the W3C CSS validation service causes problems for the W3C Markup service. LOL
Choose your battles wisely. I personally prefer W3C Markup Validation. :)
