HTML markup errors and warnings
(Rescan now...)
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “type” attribute for the “style” element is not needed and should be omitted.
The “banner” role is unnecessary for element “header”.
The “navigation” role is unnecessary for element “nav”.
The “button” role is unnecessary for element “button”.
The “main” role is unnecessary for element “main”.
The “contentinfo” role is unnecessary for element “footer”.
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).
Errors:
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
No space between attributes.
No “p” element in scope but a “p” end tag seen.
Element “style” not allowed as child of element “aside” in this context. (Suppressing further errors from this subtree.)
Element “style” not allowed as child of element “section” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “generator nofollow” for attribute “rel” on element “a”: The string “generator” is not a registered keyword.
