(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.
Attribute “placeholder” is only allowed when the input type is “email”, “number”, “password”, “search”, “tel”, “text”, or “url”.
Element “img” is missing required attribute “src”.
No “p” element in scope but a “p” end tag seen.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Duplicate ID “ownrisk”.
Warnings:
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
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).
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The first occurrence of ID “ownrisk” was here.
This document appears to be written in Dutch but the “html” start tag has “lang="en"”. Consider using “lang="nl"” (or variant) instead.
