HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “100%” for attribute “width” on element “img”: Expected a digit but saw “%” instead.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
End tag for “body” seen, but there were unclosed elements.
Unclosed element “div”.
Warnings:
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
Empty heading.
