HTML markup errors and warnings
(Rescan now...)
Warnings:
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).
Potentially bad value “allow-same-origin allow-scripts allow-popups” for attribute “sandbox” on element “iframe”: Setting both “allow-scripts” and “allow-same-origin” is not recommended, because it effectively enables an embedded page to break out of all sandboxing.
Errors:
No “p” element in scope but a “p” end tag seen.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Text not allowed in element “iframe” in this context.
Element “h2” not allowed as child of element “a” in this context. (Suppressing further errors from this subtree.)
Element “p” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Element “span” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
End tag “article” seen, but there were open elements.
Unclosed element “ul”.
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
The “itemprop” attribute was specified, but the element is not a property of any item.
