Errors

Attribute “xmlns:fb” not allowed here.

Attribute “xmlns:addthis” not allowed here.

Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.

Attribute “retina_logo_url” not allowed on element “img” at this point.

An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

Named character reference was not terminated by a semicolon. (Or “&” should have been escaped as “&”.)

Attribute “allow” not allowed on element “iframe” at this point.

Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)

Warnings

Attribute with the local name “xmlns:fb” is not serializable as XML 1.0.

Attribute with the local name “xmlns:addthis” is not serializable as XML 1.0.

The “main” role is unnecessary for element “main”.

The “contentinfo” role is unnecessary for element “footer”.

Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.

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).
