Bad value “cn_kan” for attribute “hreflang” on element “link”: The language subtag “cn_kan” is not a valid language subtag.
The “hspace” attribute on the “img” element is obsolete. Use CSS instead.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
No space between attributes.
Quote “"” in attribute name. Probable cause: Matching quote missing somewhere earlier.
Attribute “45"” not allowed on element “img” at this point.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
The “name” attribute on the “img” element is obsolete. Use the “id” attribute instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Warnings:
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
Attribute “45"” is not serializable as XML 1.0.
