(Rescan now...)
Errors:
X-UA-Compatible HTTP header must have the value “IE=edge”, was “IE=edge,chrome=1”.
A document must not include more than one “meta” element with its “name” attribute set to the value “description”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Saw “</>”. Probable causes: Unescaped “<” (escape as “<”) or mistyped end tag.
Element “summary” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Duplicate attribute “itemprop”.
Element “abbr” not allowed as child of element “time” in this context. (Suppressing further errors from this subtree.)
The text content of element “time” was not in the required format: The literal did not satisfy the time-datetime format.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “type” attribute is unnecessary for JavaScript resources.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “banner” role is unnecessary for element “header”.
Empty heading.
The “navigation” role is unnecessary for element “nav”.
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).
