HTML markup errors and warnings
(Rescan now...)
Errors:
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Legacy doctype. Expected “<!DOCTYPE html>”.
Bad value “https://www.w3.org/1999/xhtml” for the attribute “xmlns” (only “http://www.w3.org/1999/xhtml” permitted here).
Attribute “custom-element” not allowed on element “script” at this point.
The element “a” must not appear as a descendant of the “button” element.
No “li” element in scope but a “li” end tag seen.
No “p” element in scope but a “p” end tag seen.
Element “div” not allowed as child of element “small” in this context. (Suppressing further errors from this subtree.)
Element “ul” not allowed as child of element “small” in this context. (Suppressing further errors from this subtree.)
The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “{” instead.
The “aria-labelledby” attribute must point to an element in the same document.
Warnings:
Attribute “xmlns” is not serializable as XML 1.0.
The “type” attribute is unnecessary for JavaScript resources.
Consider avoiding viewport values that prevent users from resizing documents.
The “charset” attribute on the “script” element is obsolete.
The “navigation” role is unnecessary for element “nav”.
