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.
Element “meta” is missing one or more of the following attributes: “content”, “itemprop”, “property”.
Element “li” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Named character reference was not terminated by a semicolon. (Or “&” should have been escaped as “&”.)
The “width” attribute on the “td” element is obsolete. Use CSS instead.
Element “script” must not have attribute “charset” unless attribute “src” is also specified.
Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
