Errors:
Obsolete doctype. Expected “<!DOCTYPE html>”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

Duplicate attribute “class”.
Attribute “name” not allowed on element “div” at this point.
The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “{” instead.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Bad value “” for attribute “usemap” on element “img”: The empty string is not a valid hash-name reference.
The element “img” with the attribute “usemap” must not appear as a descendant of the “a” element.
Element “area” is missing required attribute “alt”.
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
The “align” attribute on the “div” element is obsolete. Use CSS instead.

The “itemprop” attribute was specified, but the element is not a property of any item.
Warnings:
The “banner” role is unnecessary for element “header”.
Empty heading.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
The “contentinfo” role is unnecessary for element “footer”.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
