Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
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).
Errors:
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Bad value “” for attribute “target” on element “a”: Browsing context name must be at least one character long.
The element “button” must not appear as a descendant of the “a” element.
Element “div” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
End tag “section” seen, but there were open elements.
Unclosed element “div”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
