HTML markup errors and warnings
(Rescan now...)
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).
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
Attribute “color:#fff;” is not serializable as XML 1.0.
Errors:
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
End tag “div” seen, but there were open elements.
Unclosed element “header”.
Stray end tag “header”.
Bad value “” for attribute “action” on element “form”: Must be non-empty.
The “clear” attribute on the “br” element is obsolete. Use CSS instead.
The “center” element is obsolete.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.
No space between attributes.
Attribute “color:#fff;” not allowed on element “h3” at this point.
No “p” element in scope but a “p” end tag seen.
Element “p” not allowed as child of element “h3” in this context. (Suppressing further errors from this subtree.)
