Errors:
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Element “p” not allowed as child of element “h1” in this context. (Suppressing further errors from this subtree.)
No “p” element in scope but a “p” end tag seen.
Element “style” not allowed as child of element “aside” in this context. (Suppressing further errors from this subtree.)
Bad value “generator” for attribute “rel” on element “a”: The string “generator” is not a registered keyword.
Warnings:
The “banner” role is unnecessary for element “header”.
The “navigation” role is unnecessary for element “nav”.

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).
