Errors:
A “link” element with a “sizes” attribute must have a “rel” attribute that contains the value “icon” or the value “apple-touch-icon”.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
The “center” element is obsolete. Use CSS instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
End tag “p” implied, but there were open elements.
Unclosed element “strong”.
No “p” element in scope but a “p” end tag seen.
