Errors:
X-UA-Compatible HTTP header must have the value “IE=edge”, was “IE=edge,chrome=1”.
Attribute “data” not allowed on element “meta” at this point.
Element “meta” is missing one or more of the following attributes: “http-equiv”, “itemprop”, “name”, “property”.
Element “script” must not have attribute “async” unless attribute “src” is also specified or unless attribute “type” is specified with value “module”.
Start tag “a” seen but an element of the same type was already open.
End tag “a” violates nesting rules.
Stray end tag “span”.
Stray end tag “a”.
Element “img” is missing required attribute “src”.
Element “style” not allowed as child of element “li” in this context. (Suppressing further errors from this subtree.)
Element “style” not allowed as child of element “footer” in this context. (Suppressing further errors from this subtree.)

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 “type” attribute for the “style” element is not needed and should be omitted.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Consider adding a “lang” attribute to the “html” start tag to declare the language of this document.
