(Rescan now...)
Errors:
Bad value “6c4ee411648f8e71eeb3b8e2-” for attribute “type” on element “script”: Subtype missing.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
A “script” element with the “language="JavaScript"” attribute set must not have a “type” attribute whose value is not “text/javascript”.
The “center” element is obsolete. Use CSS instead.
Saw “<” when expecting an attribute name. Probable cause: Missing “>” immediately before.
Attribute “<” not allowed on element “img” at this point.
Attribute “a” not allowed on element “img” at this point.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
No “p” element in scope but a “p” end tag seen.
Element “p” not allowed as child of element “h3” in this context. (Suppressing further errors from this subtree.)
Element “script” must not have attribute “async” unless attribute “src” is also specified.
Warnings:
The “complementary” role is unnecessary for element “aside”.
Attribute “<” is not serializable as XML 1.0.
The “article” role is unnecessary for element “article”.
The “contentinfo” role is unnecessary for element “footer”.
