Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Bad value “Content-Style-Type” for attribute “http-equiv” on element “meta”.
Bad start tag in “img” in “head”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Stray end tag “noscript”.
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.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
Element “input” with attribute “type” whose value is “button” must have non-empty attribute “value”.
Element “div” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Attribute “addthis:url” not allowed on element “div” at this point.
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).

The “font” element is obsolete. Use CSS instead.
Warnings:
The “language” attribute on the “script” element is obsolete. You can safely omit it.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Attribute “addthis:url” is not serializable as XML 1.0.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
