Errors:
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
A “link” element with a “sizes” attribute must have a “rel” attribute that contains the value “icon” or the value “apple-touch-icon”.
Duplicate ID “post-21023”.
No “p” element in scope but a “p” end tag seen.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Attribute “border” not allowed on element “input” at this point.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Warnings:
The “navigation” role is unnecessary for element “nav”.
The “button” role is unnecessary for element “button”.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
The “main” role is unnecessary for element “main”.
The first occurrence of ID “post-21023” was here.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
This document appears to be written in Danish but the “html” start tag has “lang="en-US"”. Consider using “lang="da"” (or variant) instead.
