HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “icon” for attribute “type” on element “link”: Subtype missing.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
No “p” element in scope but a “p” end tag seen.
Element “div” not allowed as child of element “cite” in this context. (Suppressing further errors from this subtree.)
Quote “"” in attribute name. Probable cause: Matching quote missing somewhere earlier.
Attribute “btn-md"” not allowed on element “a” at this point.
The “aria-labelledby” attribute must point to an element in the same document.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “navigation” role is unnecessary for element “nav”.
Attribute “btn-md"” is not serializable as XML 1.0.
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
