You want to be using the iframe s srcdoc attribute for that  MDN documentation   var html string    quot  lt html gt  lt body gt  lt h1 gt My epic iframe lt  p gt  lt  body gt  lt  html gt  quot   document querySelector  iframe   srcdoc   html string   The nice thing about using this method over for example Red s method listed on this page  is that iframe contents added with srcdoc are seen as the same-origin  That way can continue to manipulate and access the iframe with JavaScript if you wish
