The “profile” attribute on the “head” element is obsolete.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.
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
Text not allowed in element “iframe” in this context.
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
Bad value “” for attribute “name” on element “button”: Must not be empty.
Attribute “about” not allowed on element “div” at this point.
Attribute “content” not allowed on element “span” at this point.
Bad value “auto” for attribute “height” on element “img”: Expected a digit but saw “a” instead.
Attribute “name” not allowed on element “meta” at this point.
Element “meta” is missing one or more of the following attributes: “itemprop”, “property”.
The “itemprop” attribute was specified, but the element is not a property of any item.

The “banner” role is unnecessary for element “header”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “navigation” role is unnecessary for element “nav”.
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).
