Warnings

Attribute “name” not allowed on element “meta” at this point.

Element “meta” is missing one or more of the following attributes: “itemprop”, “property”.

Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.

Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)

No space between attributes.

Bad value “_new” for attribute “target” on element “a”: Reserved keyword “new” used.
