HTML markup errors and warnings
(Rescan now...)
Errors:
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Attribute “xmlns:fb” not allowed here.
Bad value “Content-Script-Type” for attribute “http-equiv” on element “meta”.
Bad value “Content-Style-Type” for attribute “http-equiv” on element “meta”.
No space between attributes.
A slash was not immediately followed by “>”.
Saw “"” when expecting an attribute name. Probable cause: “=” missing immediately before.
Attribute “"” not allowed on element “img” at this point.
End tag for “body” seen, but there were unclosed elements.
Unclosed element “div”.
Warnings:
Attribute with the local name “xmlns:fb” 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.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
