(Rescan now...)
Errors:
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
Attribute “width” not allowed on element “meta” at this point.
Element “meta” is missing one or more of the following attributes: “content”, “property”.
Element “noindex” 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.
The “language” attribute on the “script” element is obsolete. Use the “type” attribute instead.
Element “noindex” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Warnings:
The “language” attribute on the “script” element is obsolete.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The “border” attribute is obsolete.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.
