HTML markup errors and warnings
(Rescan now...)
Errors:
Stray start tag “html”.
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
The “center” element is obsolete. Use CSS instead.
Attribute “pubdate” not allowed on element “time” at this point.
Bad value “2018-03-4” for attribute “datetime” on element “time”: The literal did not satisfy the time-datetime format.
Bad value “2018-03-3” for attribute “datetime” on element “time”: The literal did not satisfy the time-datetime format.
Element “div” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
End tag “ul” seen, but there were open elements.
Unclosed element “div”.
Warnings:
The “banner” role is unnecessary for element “header”.
The “navigation” role is unnecessary for element “nav”.
The “article” role is unnecessary for element “article”.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
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).
