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.
Attribute “aria-selected” not allowed on element “style” at this point.
Bad value “https://theeventscalendar.com/” for attribute “rel” on element “link”: The string “https://theeventscalendar.com/” is not a registered keyword.
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Bad value for attribute “href” on element “a”: Illegal character in query: space is not allowed.
Duplicate ID “fb-root”.
Quote “"” in attribute name. Probable cause: Matching quote missing somewhere earlier.
“data-*” attribute names must be XML 1.0 4th ed. plus Namespaces NCNames.
Warnings:
The “banner” role is unnecessary for element “header”.
The “main” role is unnecessary for element “main”.
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).
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The first occurrence of ID “fb-root” was here.
Attribute “data-width:"100%"” is not serializable as XML 1.0.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
The “contentinfo” role is unnecessary for element “footer”.
