HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Attribute “xmlns:v” not allowed here.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
No “p” element in scope but a “p” end tag seen.
Element “br” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Stray end tag “h2”.
End tag “p” seen, but there were open elements.
Unclosed element “a”.
Start tag “a” seen but an element of the same type was already open.
End tag “a” violates nesting rules.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
The “language” attribute on the “script” element is obsolete. You can safely omit it.
Attribute with the local name “xmlns:v” is not serializable as XML 1.0.
The “complementary” role is unnecessary for element “aside”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
