HTML markup errors and warnings
(Rescan now...)
Warnings:
Document uses the Unicode Private Use Area(s), which should not be used in publicly exchanged documents. (Charmod C073)
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).
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
The first occurrence of ID “” was here.
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
Errors:
Attribute “gtm-id” not allowed on element “a” at this point.
No “p” element in scope but a “p” end tag seen.
Bad value “” for attribute “id” on element “div”: An ID must not be the empty string.
Duplicate ID “”.
The element “button” must not appear as a descendant of the “a” element.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Element “span” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
