Bugzilla – Bug 724
body@margintop and body@marginheight should be reported as obsolete presentational attributes, not unknown attributes
Last modified: 2010-04-10 00:27:11 CEST
When validating www.google.com, validator.nu flags margintop and marginheight with this error: Error: Attribute topmargin not allowed on element body at this point. But most presentational attributes have an error message like this: Error: The bgcolor attribute on the body element is obsolete. Use CSS instead.
I fixed this recently in bug 730 You can test it now at http://www.w3.org/html/check
