HTML markup errors and warnings
(Rescan now...)
Errors:
Bogus doctype.
Quirky doctype. Expected “<!DOCTYPE html>”.
The “profile” attribute on the “head” element is obsolete.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 “https://fonts.googleapis.com/css?family=Lato:400,700,400italic,700italic|Oswald:400,700” for attribute “href” on element “link”: Illegal character in query: “|” is not allowed.
Text not allowed in element “ul” in this context.
Element “a” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
The value of the “for” attribute of the “label” element must be the ID of a non-hidden form control.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “type” attribute is unnecessary for JavaScript resources.
The “type” attribute for the “style” element is not needed and should be omitted.
Consider adding a “lang” attribute to the “html” start tag to declare the language of this document.
