Is there a way to specify the css version in a document?
It seems very strange to me if you can’t. X/HTML has ridiculously detailed doctypes, yet CSS you can’t even specify it?
Hi,
There is only one single version of CSS although it does have levels. 
The way that CSS is designed means that it doesn’t need versioning.
Probably best if you read this short article that explains the reasoning behind it
Cool, thanks for the info
