(Rescan now...)
Warnings:

Attribute “allow” not allowed on element “iframe” at this point.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Duplicate attribute “class”.
Attribute “a” not allowed on element “a” at this point.
End tag “p” implied, but there were open elements.
Unclosed element “span”.
Stray end tag “span”.
No “p” element in scope but a “p” end tag seen.

The “for” attribute of the “label” element must refer to a non-hidden form control.
The “aria-labelledby” attribute must point to an element in the same document.
