Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Bad value “https://www.w3.org/1999/xhtml” for the attribute “xmlns” (only “http://www.w3.org/1999/xhtml” permitted here).
The “profile” attribute on the “head” element is obsolete. To declare which “meta” terms are used in the document, instead register the names as meta extensions. To trigger specific UA behaviors, use a “link” element instead.
Bad value “screen, projection” for attribute “media” on element “link”: Deprecated media type “projection”. For guidance, see the Media Types section in the current Media Queries specification.
Saw “<” when expecting an attribute name. Probable cause: Missing “>” immediately before.
A slash was not immediately followed by “>”.
Attribute “<” not allowed on element “script” at this point.
Attribute “script” not allowed on element “script” at this point.
The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “<” instead.
The “center” element is obsolete. Use CSS instead.
Stray end tag “center”.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
Element “g:plusone” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Element “p” not allowed as child of element “h3” in this context. (Suppressing further errors from this subtree.)
The “align” attribute on the “p” element is obsolete. Use CSS instead.
No “p” element in scope but a “p” end tag seen.
End tag “div” seen, but there were open elements.
Unclosed element “center”.
Stray end tag “div”.
End tag “br”.
Warnings:
Attribute “xmlns” is not serializable as XML 1.0.
The “type” attribute is unnecessary for JavaScript resources.
The “type” attribute for the “style” element is not needed and should be omitted.
Attribute “<” is not serializable as XML 1.0.
Element name “g:plusone” cannot be represented as XML 1.0.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
