Hi Neil, I agree, there will be a lot of obvious benefits, but in the other hand it could become a lot of new issues. So what the point, if all CSS source including in the file, the file size will be much bigger, but I think if would be possible to use containers to design the content the source will be a little bit smarter. So at least we take a pass on <link rel="stylesheet" type="text/css" href="*.css">. Right?
