(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.
Bad value “Content-Script-Type” for attribute “http-equiv” on element “meta”.
Bad value “Content-Style-Type” for attribute “http-equiv” on element “meta”.
A document must not include more than one “meta” element with its “name” attribute set to the value “description”.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Attribute “xmlns:svgjs” not allowed here.
Stray end tag “a”.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
Attribute with the local name “xmlns:svgjs” is not serializable as XML 1.0.
Empty heading.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
