HTML markup errors and warnings
(Rescan now...)
Errors:
Attribute “amp” not allowed on element “html” at this point.
The “center” element is obsolete. Use CSS instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “figcaption” not allowed as child of element “a” in this context. (Suppressing further errors from this subtree.)
Start tag “a” seen but an element of the same type was already open.
Stray end tag “a”.
End tag “section” seen, but there were open elements.
Unclosed element “div”.
Element “img” is missing required attribute “src”.
Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
