Bad value “imagetoolbar” for attribute “http-equiv” on element “meta”.
The “language” attribute on the “script” element is obsolete. Use the “type” attribute instead.
CSS: Parse Error.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
The “type” attribute for the “style” element is not needed and should be omitted.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
