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>”.
Bad value “Content-Style-Type” for attribute “http-equiv” on element “meta”.
Bad value “Content-Script-Type” for attribute “http-equiv” on element “meta”.
A document must not include more than one “meta” element with a “http-equiv” attribute whose value is “content-type”.
Bad element name “gcse:searchbox-only”: Code point “U+003A” is not allowed
The element “img” with the attribute “usemap” must not appear as a descendant of the “a” element.
Element “area” is missing required attribute “alt”.
Text not allowed in element “ul” in this context.
Warnings:
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
Element name “gcse:searchbox-only” cannot be represented as XML 1.0.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
