Element “meta” is missing one or more of the following attributes: “charset”, “content”, “http-equiv”, “itemprop”, “name”, “property”.

Bad value “cleartype” for attribute “http-equiv” on element “meta”.

A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.

Bad value “” for attribute “name” on element “input”: Must not be empty.
