Errors:
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
No space between attributes.
A slash was not immediately followed by “>”.
Quote “"” in attribute name. Probable cause: Matching quote missing somewhere earlier.
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
Attribute “http:” not allowed on element “html” at this point.
Attribute “ogp.me” not allowed on element “html” at this point.
Attribute “ns” not allowed on element “html” at this point.

Bad value “Content-Script-Type” for attribute “http-equiv” on element “meta”.
Bad value “Content-Style-Type” for attribute “http-equiv” on element “meta”.
Bad start tag in “img” in “head”.
Element “head” is missing a required instance of child element “title”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Stray end tag “noscript”.
A “link” element must not appear as a descendant of a “body” element unless the “link” element has an “itemprop” attribute or has a “rel” attribute whose value contains “dns-prefetch”, “modulepreload”, “pingback”, “preconnect”, “prefetch”, “preload”, “prerender”, or “stylesheet”.
Element “title” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Attribute “name” not allowed on element “meta” at this point.
Element “meta” is missing one or more of the following attributes: “itemprop”, “property”.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
Attribute “http:” is not serializable as XML 1.0.

The “type” attribute for the “style” element is not needed and should be omitted.
