Invalid HTML in Google’s Homepage

When validating my homepage /me got 1Error and 1warning, was curious to paw more!

w3.org validator says : 37 Errors, 2 warning(s) on validation of google.com! Edit 1 : It says : 39 Errors, 2 warning(s) /me loves reading obfuscated code, with javascript in view on of the most obfuscated code can be found in the source pages of google pages, may it be gmail, g+ or even their 404 page! It’s fun reading it.

But for my shock here are the list of errors that was found in google.com

Including errors like :

• Attribute width not allowed on element div at this point.
• The center element is obsolete. Use CSS instead.
• The clear attribute on the br element is obsolete. Use CSS instead. Many more
• End of file seen and there were open elements!!
• Unclosed element center!!

List of other sites that failed :

• facebook.com 41 Errors
• twitter.com 2 Errors, 1 warning(s)
• firefox.com 1 Error, 1 warning(s)
• wikipedia.org 5 Errors, 24 warning(s) Stopped after that! Some of them that passed :
• Opera.com
• gnu.org
• stallman.org Yes indeed the HTML5 parser is rapidly changing and this stats might be wrong sooner, but just for some study this data was collected and shared!__
