(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Bad value “screen, projection” for attribute “media” on element “link”: Deprecated media type “projection”. For guidance, see the Media Types section in the current Media Queries specification.
Bad value “handheld” for attribute “media” on element “link”: Deprecated media type “handheld”. For guidance, see the Media Types section in the current Media Queries specification.
Element “meta” is missing one or more of the following attributes: “content”, “property”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad value “” for attribute “target” on element “a”: Browsing context name must be at least one character long.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “for” attribute of the “label” element must refer to a non-hidden form control.
Warnings:
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
This document appears to be written in English but the “html” start tag has an empty “lang” attribute. Consider using “lang="en"” (or variant) instead.
