HTML markup errors and warnings
(Rescan now...)
Errors:
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “noindex” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
The “center” element is obsolete. Use CSS instead.
Attribute “name” not allowed on element “meta” at this point.
Element “meta” is missing one or more of the following attributes: “itemprop”, “property”.
The text content of element “time” was not in the required format: The literal did not satisfy the time-datetime format.
The “align” attribute on the “img” element is obsolete. Use CSS instead.
Named character reference was not terminated by a semicolon. (Or “&” should have been escaped as “&”.)
Stray start tag “script”.
The “itemprop” attribute was specified, but the element is not a property of any item.
Warnings:
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
