HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode 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).
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad value “none” for attribute “media” on element “link”: Media query ended prematurely.
Bad value “true” for attribute “async” on element “script”.
Element “ul” not allowed as child of element “span” 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.
Element “p” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Text not allowed in element “ul” in this context.
The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “l” instead.
Warnings:
Attribute “xmlns” is not serializable as XML 1.0.
The “type” attribute is unnecessary for JavaScript resources.
Consider adding a “lang” attribute to the “html” start tag to declare the language of this document.
