Hello,

I was validating an HTML page CSS with http://jigsaw.w3.org/css-validator/
and I got multiple errors.

The problem was that I my CSS seemed fine and I was not getting any
detail about the errors.

Then I removed the comment I had on the start of each CSS file and all
the errors disappeared.

Can't a CSS file start with a comment to be validated?

.... I have seen many CSS documents that start with a comment.

Thank You,
Miguel
