HTML markup errors and warnings
(Rescan now...)
Warnings:
The “banner” role is unnecessary for element “header”.
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).
The “main” role is unnecessary for element “main”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “contentinfo” role is unnecessary for element “footer”.
Errors:
Element “div” not allowed as child of element “h1” in this context. (Suppressing further errors from this subtree.)
The element “header” must not appear as a descendant of the “header” element.
Bad character “お” after “<”. Probable cause: Unescaped “<”. Try escaping it as “<”.
Element “li” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “img” is missing required attribute “src”.
End tag “main” seen, but there were open elements.
Unclosed element “div”.
