Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Errors:
Bad start tag in “img” in “head”.
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”.
Attribute “name” not allowed on element “meta” at this point.
Element “meta” is missing one or more of the following attributes: “itemprop”, “property”.
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”, “pingback”, “preconnect”, “prefetch”, “preload”, “prerender”, or “stylesheet”.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Bad value “jp” for attribute “hreflang” on element “link”: The language subtag “jp” is not a valid ISO language part of a language tag.
Stray end tag “head”.
