Errors:
Attribute “allow” not allowed on element “iframe” at this point.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Duplicate attribute “style”.
End tag “section” seen, but there were open elements.
Unclosed element “div”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “navigation” for attribute “role” on element “ul”.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Bad value “noindex” for attribute “rel” on element “a”: The string “noindex” is not a registered keyword.
Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
