HTML markup errors and warnings
(Rescan now...)
Errors:
Legacy doctype. Expected “<!DOCTYPE html>”.
Stray doctype.
Bad value “https://www.w3.org/1999/xhtml” for the attribute “xmlns” (only “http://www.w3.org/1999/xhtml” permitted here).
The “profile” attribute on the “head” element is obsolete.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 “text/html; charset=utf-8; ?>” for attribute “content” on element “meta”: The legacy encoding contained “;”, which is not a valid character in an encoding name.
Duplicate ID “menu-item-91”.
Element “li” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Duplicate ID “text-13”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
No “p” element in scope but a “p” end tag seen.
Warnings:
Attribute “xmlns” is not serializable as XML 1.0.
The first occurrence of ID “menu-item-91” was here.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
The first occurrence of ID “text-13” was here.
