Errors:
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
No space between attributes.
Saw “"” when expecting an attribute name. Probable cause: “=” missing immediately before.
Attribute “"” not allowed on element “meta” at this point.
Bad value “” for attribute “id” on element “div”: An ID must not be the empty string.
Bad value “” for attribute “src” on element “img”: Must be non-empty.
Bad value “ 425w,
1024w” for attribute “srcset” on element “img”: Density for image “1024w” is identical to density for image “425w”.
Element “script” must not have attribute “defer” unless attribute “src” is also specified.
Warnings:
Attribute “"” is not serializable as XML 1.0.
