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.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Stray end tag “img”.
The “sizes” attribute may be specified only if the “srcset” attribute is also present.
Bad value “100%” for attribute “width” on element “iframe”: Expected a digit but saw “%” instead.
Attribute “allow” not allowed on element “iframe” at this point.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
No “p” element in scope but a “p” end tag seen.
Saw “<” when expecting an attribute name. Probable cause: Missing “>” immediately before.
A slash was not immediately followed by “>”.
Attribute “<” not allowed on element “img” at this point.
Attribute “div” not allowed on element “img” at this point.
End tag “br”.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
End tag for “body” seen, but there were unclosed elements.
Unclosed element “div”.
Warnings:
The “navigation” role is unnecessary for element “nav”.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
Attribute “<” is not serializable as XML 1.0.
