Errors:
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Attribute “allow” not allowed on element “iframe” at this point.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Attribute “type” not allowed on element “div” at this point.
Element “div” is missing one or more of the following attributes: “role”.
Duplicate ID “purpose-other”.
Attribute “rold” not allowed on element “a” at this point.
Duplicate ID “gform_38”.
Saw a “form” start tag, but there was already an active “form” element. Nested forms are not allowed. Ignoring the tag.
End tag “form” seen, but there were open elements.
Unclosed element “div”.
Unclosed element “fieldset”.
Cannot recover after last error. Any further errors will be ignored.
