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.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Duplicate attribute “href”.
Duplicate ID “xx”.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
No space between attributes.
End tag “div” seen, but there were open elements.
Unclosed element “form”.
Saw “=” when expecting an attribute name. Probable cause: Attribute name missing.
Quote “"” in attribute name. Probable cause: Matching quote missing somewhere earlier.
Attribute “=""” not allowed on element “img” at this point.
Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “navigation” role is unnecessary for element “nav”.
The first occurrence of ID “xx” was here.
Attribute “=""” is not serializable as XML 1.0.
