HTML markup errors and warnings
(Rescan now...)
Errors:
A “link” element with a “sizes” attribute must have a “rel” attribute that contains the value “icon” or the value “apple-touch-icon”.
Bad value “” for attribute “id” on element “body”: An ID must not be the empty string.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Attribute “alt” not allowed on element “a” at this point.
Duplicate ID “search”.
End tag “section” seen, but there were open elements.
Unclosed element “div”.
Element “h10” not allowed as child of element “p” in this context. (Suppressing further errors from this subtree.)
No “p” element in scope but a “p” end tag seen.
Element “h7” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Element “h10” not allowed as child of element “a” in this context. (Suppressing further errors from this subtree.)
Element “h8” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Element “h9” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Stray end tag “source”.
The “aria-labelledby” attribute must point to an element in the same document.
Warnings:
The “navigation” role is unnecessary for element “nav”.
The first occurrence of ID “search” was here.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
