A document must not include more than one “meta” element with its “name” attribute set to the value “description”.
Stray end tag “nav”.
The “center” element is obsolete. Use CSS instead.
Element “style” not allowed as child of element “center” in this context. (Suppressing further errors from this subtree.)
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
End tag “div” seen, but there were open elements.
Unclosed element “footer”.

Warnings:
The “type” attribute is unnecessary for JavaScript resources.

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).

The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
Consider adding a “lang” attribute to the “html” start tag to declare the language of this document.
