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.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
The “font” element is obsolete.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 “br”.
End tag “span” seen, but there were open elements.
Unclosed element “font”.
No space between attributes.
End tag “strong” violates nesting rules.
No “font” element in scope but a “font” end tag seen.
Text not allowed in element “iframe” in this context.
Attribute “rel” not allowed on element “ul” at this point.
Warnings:
The “banner” role is unnecessary for element “header”.
Empty heading.
The “navigation” role is unnecessary for element “nav”.
The “main” role is unnecessary for element “main”.
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).
