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.
Stray end tag “head”.
Bad value “150px” for attribute “width” on element “img”: Expected a digit but saw “p” instead.
Bad value “50%” for attribute “width” on element “img”: Expected a digit but saw “%” instead.
Duplicate ID “ubermenu-nav-main-122-header”.
End tag “br”.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
No “p” element in scope but a “p” end tag seen.
The “center” element is obsolete. Use CSS instead.
Quote “"” in attribute name. Probable cause: Matching quote missing somewhere earlier.
Attribute “rel"nofollow"” not allowed on element “a” at this point.
The element “input” must not appear as a descendant of the “a” element.
Duplicate ID “copyright”.
Warnings:
The first occurrence of ID “ubermenu-nav-main-122-header” was here.
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).
Attribute “rel"nofollow"” is not serializable as XML 1.0.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The first occurrence of ID “copyright” was here.
