HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Bad value “https://fonts.googleapis.com/css?family=Oswald&text=0123456789./\%” for attribute “href” on element “link”: Illegal character in query: “\” is not allowed.
The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “g” instead.
Element “spn” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Attribute “alt” not allowed on element “a” at this point.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
The “itemprop” attribute was specified, but the element is not a property of any item.
