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The “profile” attribute on the “head” element is obsolete.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.
Element “title” not allowed as child of element “head” in this context. (Suppressing further errors from this subtree.)
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Duplicate ID “related-posts-MRP_all”.
The “for” attribute of the “label” element must refer to a non-hidden form control.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
The first occurrence of ID “related-posts-MRP_all” was here.
Empty heading.
