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).
Bad value “true” for attribute “async” on element “script”.
Element “script” must not have attribute “async” unless attribute “src” is also specified.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
Element “h3” not allowed as child of element “small” in this context. (Suppressing further errors from this subtree.)
Element “p” 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.)
Bad value “generator” for attribute “rel” on element “a”: The string “generator” is not a registered keyword.
Warnings:
Attribute “xmlns” is not serializable as XML 1.0.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
