Errors:
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Attribute “name” not allowed on element “meta” at this point.
Element “meta” is missing one or more of the following attributes: “itemprop”, “property”.
Bad value “” for attribute “for” on element “label”: An ID must not be the empty string.
Any “input” descendant of a “label” element with a “for” attribute must have an ID value that matches that “for” attribute.
Element “noindex” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
The “language” attribute on the “script” element is obsolete. Use the “type” attribute instead.
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
The “for” attribute of the “label” element must refer to a non-hidden form control.
Warnings:
Empty heading.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
