HTML markup errors and warnings
(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”.
Element “panel” not allowed as child of element “form” in this context. (Suppressing further errors from this subtree.)
The “language” attribute on the “script” element is obsolete. Use the “type” attribute instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Duplicate attribute “name”.
Warnings:
The “navigation” role is unnecessary for element “nav”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
