HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “dns-preconnect” for attribute “rel” on element “link”: The string “dns-preconnect” is not a registered keyword.
Element “img” is missing required attribute “src”.
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Duplicate attribute “data-role”.
Element “div” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
End tag “section” seen, but there were open elements.
Unclosed element “ul”.
The “itemprop” attribute was specified, but the element is not a property of any item.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
