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 “script” must not have attribute “charset” unless attribute “src” is also specified.
Element “style” not allowed as child of element “li” in this context. (Suppressing further errors from this subtree.)
No “p” element in scope but a “p” end tag seen.
Duplicate ID “fb-root”.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Bad character “

Bad character “ ” after “<”. Probable cause: Unescaped “<”. Try escaping it as “<”.
Warnings:
The first occurrence of ID “fb-root” was here.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “contentinfo” role is unnecessary for element “footer”.
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).
