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

Bad value “mail” for attribute “type” on element “input”.
Attribute “placeholder” is only allowed when the input type is “email”, “number”, “password”, “search”, “tel”, “text”, or “url”.
