HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
The “label” element may contain at most one “button”, “input”, “meter”, “output”, “progress”, “select”, or “textarea” descendant.
Any “input” descendant of a “label” element with a “for” attribute must have an ID value that matches that “for” attribute.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “itemprop” attribute was specified, but the element is not a property of any item.
Warnings:
The “navigation” role is unnecessary for element “nav”.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
“label” element with multiple labelable descendants.
The “main” role is unnecessary for element “main”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
