HTML markup errors and warnings
(Rescan now...)
Errors:
Legacy doctype. Expected “<!DOCTYPE html>”.
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
The “version” attribute on the “html” element is obsolete. You can safely omit it.
The “profile” attribute on the “head” element is obsolete.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 “cleartype” for attribute “http-equiv” on element “meta”.
A “link” element with a “sizes” attribute must have a “rel” attribute that contains the value “icon” or the value “apple-touch-icon”.
Bad start tag in “div” in “head”.
Stray end tag “noscript”.
The text content of element “script” was not in the required format: Content contains the character sequence “<!--” without a later occurrence of the character sequence “-->”.
Stray end tag “head”.
Duplicate attribute “class”.
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.
