(Rescan now...)
Errors:
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Bad value “” for attribute “href” on element “link”: Must be non-empty.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
No space between attributes.
End tag “li” seen, but there were open elements.
Unclosed element “a”.
Start tag “a” seen but an element of the same type was already open.
No “a” element in scope but a “a” end tag seen.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
End tag “div” seen, but there were open elements.
The “center” element is obsolete. Use CSS instead.
Bad value “{handler: 'iframe', size: {x: 550, y: 650}}” for attribute “rel” on element “a”: The string “{handler:” is not a registered keyword.
Warnings:
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
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).
