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The “version” attribute on the “html” element is obsolete.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The “profile” attribute on the “head” element is obsolete.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.
A “link” element with a “sizes” attribute must have a “rel” attribute that contains the value “icon” or the value “apple-touch-icon”.
Element “br” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Duplicate ID “vk_head”.
Duplicate ID “insta_head”.
Duplicate ID “facebook_head”.
Duplicate ID “youtube_head”.
Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
