Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Bad start tag in “iframe” in “head”.
Stray end tag “noscript”.
Element “script” must not have attribute “charset” unless attribute “src” is also specified.
Attribute “http-equiv” not allowed on element “meta” at this point.
Element “meta” is missing one or more of the following attributes: “itemprop”, “property”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Attribute “name” not allowed on element “meta” at this point.
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”, “pingback”, “preconnect”, “prefetch”, “preload”, “prerender”, or “stylesheet”.
A “link” element with a “sizes” attribute must have a “rel” attribute that contains the value “icon” or the value “apple-touch-icon”.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “highslide-bookmarkable-{'width':'853', 'height':'517', 'objectType':'iframe'}” for attribute “rel” on element “a”: The string “highslide-bookmarkable-{'width':'853',” is not a registered keyword.
Warnings:
The “language” attribute on the “script” element is obsolete. You can safely omit it.
Consider avoiding viewport values that prevent users from resizing documents.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
