HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “ImageToolbar” for attribute “http-equiv” on element “meta”.
Attribute “rel” not allowed on element “li” at this point.
Bad value “lightframe, nofollow” for attribute “rel” on element “a”: The string “lightframe,” is not a registered keyword.
“=” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Attribute “ontouchstart” not allowed on element “div” at this point.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Attribute “i” not allowed on element “a” at this point.
Stray end tag “div”.
Element “style” not allowed as child of element “noscript” in this context. (Suppressing further errors from this subtree.)
Warnings:
The “banner” role is unnecessary for element “header”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
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”.
Empty heading.
The “contentinfo” role is unnecessary for element “footer”.
