HTML markup errors and warnings
(Rescan now...)
Errors:
Element “div” not allowed as child of element “h1” in this context. (Suppressing further errors from this subtree.)
Element “div” not allowed as child of element “h2” in this context. (Suppressing further errors from this subtree.)
“"” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.
Bad value “group"” for attribute “rel” on element “a”: The string “group"” is not a registered keyword.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
No space between attributes.
The “for” attribute of the “label” element must refer to a non-hidden form control.
Warnings:
