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.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
No “li” element in scope but a “li” end tag seen.
No “p” element in scope but a “p” end tag seen.
Attribute “alt” not allowed on element “a” at this point.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Stray start tag “style”.
Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
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).
