How does the W3C CSS Validator identify a css3 document?

I have a problem!

Is there a way to identify the css3 file for the W3C validator?

In HTML5 we put <!DOCTYPE html> , but in the CSS file, what can we put?

When I check my css file and contains some css3 elements ( @font-face , box-shadow , etc.), it says that it is invalid! because he does not know this css3. So ... is there a way?

Thank you very much. David.

No, CSS files do not have a self-identification feature. To test a file for a specific version of CSS, you must explicitly choose which version you want. In W3C Validator, this can be selected from the Profile menu in the Advanced Options section.

CSS 3 is what it stands for; until all CSS3 modules are complete (don't hold your breath!) it's debatable what that means ...

James's code broke because he didn't wrap it in code tags, but here is the actual code

 http://jigsaw.w3.org/css-validator/validator?profile=css3&usermedium=all&warning=1&vextwarning=&lang=en&uri=http%3A%2F%2Fwww.yourwebsitename.com%2F

However, this will violate your W3C validation check.

 cannot generate system identifier for general entity "usermedium" …/css-validator/validator?profile=css3&usermedium=all&warning=1&vextwarning=&la… general entity "usermedium" not defined and no default entity …/css-validator/validator?profile=css3&usermedium=all&warning=1&vextwarning=&la… reference not terminated by REFC delimiter …ator/validator?profile=css3&usermedium=all&warning=1&vextwarning=&lang=en&uri=… reference to external entity in attribute value …ator/validator?profile=css3&usermedium=all&warning=1&vextwarning=&lang=en&uri=… reference to entity "usermedium" for which no system identifier could be generated …ator/validator?profile=css3&usermedium=all&warning=1&vextwarning=&lang=en&uri=… cannot generate system identifier for general entity "warning" …validator?profile=css3&usermedium=all&warning=1&vextwarning=&lang=en&uri=http%…

It seems strange to me that the code generated by the W3C CSS validation service disrupts the W3C Markup service. Lol

So take your poison. I adhere to the W3C Markup Validation. :)
