HTML markup errors and warnings
(Rescan now...)
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “date” input type is not supported in all browsers. Please be sure to test, and consider using a polyfill.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “banner” role is unnecessary for element “header”.
The “charset” attribute on the “script” element is obsolete.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
Errors:
Attribute “ng-controller” not allowed on element “span” at this point.
Attribute “placeholder” is only allowed when the input type is “email”, “number”, “password”, “search”, “tel”, “text”, or “url”.
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Attribute “id-2019” not allowed on element “span” at this point.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
End tag “h3” seen, but there were open elements.
Unclosed element “span”.
The “itemprop” attribute was specified, but the element is not a property of any item.
