A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
CSS: “background-color”: Parse Error.
Attribute “hundredbit” not allowed on element “li” at this point.
Bad value “text” for attribute “type” on element “script”: Subtype missing.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
