HTML markup errors and warnings
(Rescan now...)
Errors:
Legacy doctype. Expected “<!DOCTYPE html>”.
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
The “version” attribute on the “html” element is obsolete. You can safely omit it.
The “profile” attribute on the “head” element is obsolete.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.
Attribute “alt” not allowed on element “a” at this point.
Attribute “pages” not allowed on element “ul” at this point.
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “$” instead.
No space between attributes.
Duplicate attribute “class”.
The “itemprop” attribute was specified, but the element is not a property of any item.
Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
