HTML markup errors and warnings
(Rescan now...)
Errors:
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
A “link” element with a “sizes” attribute must have a “rel” attribute that contains the value “icon” or the value “apple-touch-icon”.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
The element “footer” must not appear as a descendant of the “header” element.
Duplicate ID “menu-footerbottom”.
End tag for “body” seen, but there were unclosed elements.
Unclosed element “div”.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The first occurrence of ID “menu-footerbottom” 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).
