HTML markup errors and warnings
(Rescan now...)
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The “profile” attribute on the “head” element is obsolete.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The “align” attribute on the “img” element is obsolete. Use CSS instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Duplicate ID “title”.
End tag “br”.
No “p” element in scope but a “p” end tag seen.
Named character reference was not terminated by a semicolon. (Or “&” should have been escaped as “&”.)
Warnings:
The first occurrence of ID “title” was here.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
