HTML markup errors and warnings
(Rescan now...)
Errors:
Bad start tag in “img” in “head”.
Stray end tag “noscript”.
Bad value “shortcut_icon” for attribute “rel” on element “link”: The string “shortcut_icon” is not a registered keyword.
A “link” element must not appear as a descendant of a “body” element unless the “link” element has an “itemprop” attribute or has a “rel” attribute whose value contains “dns-prefetch”, “modulepreload”, “pingback”, “preconnect”, “prefetch”, “preload”, “prerender”, or “stylesheet”.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
No space between attributes.
Quote “"” in attribute name. Probable cause: Matching quote missing somewhere earlier.
Attribute “ha"” not allowed on element “div” at this point.
CSS: “data-da-type”: Parse Error.
Warnings:
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The “main” role is unnecessary for element “main”.
Attribute “ha"” is not serializable as XML 1.0.
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
