Errors

Almost standards mode doctype. Expected “<!DOCTYPE html>”.

The “profile” attribute on the “head” element is obsolete. To declare which “meta” terms are used in the document, instead register the names as meta extensions. To trigger specific UA behaviors, use a “link” element instead.

Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.

The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “{” instead.

An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

End tag “p” seen, but there were open elements.

Unclosed element “code”.

Element “p” not allowed as child of element “code” in this context. (Suppressing further errors from this subtree.)

End tag “code” violates nesting rules.

Cannot recover after last error. Any further errors will be ignored.
