HTML5 validation fails when a style element contains html comments and the following text: "empty-" (as in the CSS property "empty-cells". The following is a valid document that will fail: <!DOCTYPE html> <html> <head> <meta charset="UTF-8"/> <title>Christina Hardyment - Author and Journalist</title> <style>  </style> </head> <body> </body> </html> 55710 1 ville.skytta 2011-08-23 19:17:22 +0000 The example document no longer fails, so I'm assuming this has been fixed at some point.
