Errors:
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 “article” for attribute “itemtype” on element “meta”: The string “article” is not an absolute URL.
Element “meta” is missing one or more of the following attributes: “content”, “itemprop”, “name”.
No “p” element in scope but a “p” end tag seen.
Heading cannot be a child of another heading.
Bad value “intro-title inovative” for attribute “id” on element “h1”: An ID must not contain whitespace.
Stray end tag “h1”.
End tag “br”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “h1” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
The “itemprop” attribute was specified, but the element is not a property of any item.
Warnings:
Empty heading.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
