HTML markup errors and warnings
(Rescan now...)
Errors:
Element “meta” is missing one or more of the following attributes: “content”, “property”.
Bad value “900;URL='/'” for attribute “content” on element “meta”: Expected a space character, but saw “U” instead.
Attribute “parsetags” 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.
Duplicate attribute “class”.
The element “header” must not appear as a descendant of the “header” element.
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Start tag “a” seen but an element of the same type was already open.
End tag “a” violates nesting rules.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
