HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Duplicate attribute “prefix”.
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
Bad start tag in “img” in “head”.
Stray end tag “noscript”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Attribute “name” not allowed on element “meta” at this point.
Element “meta” is missing one or more of the following attributes: “itemprop”, “property”.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
Consider avoiding viewport values that prevent users from resizing documents.
