The header and footer should take up both of the columns.

@media (min-width: 400px){
  .container{
    grid-template-areas:
	  /* two columns shared between advert and header */
	  /* you want header to use both columns */
      "advert header"
      "advert content"
	  /* two columns shared between advert and footer */
	  /* you want footer to use both columns*/
      "advert footer";
  }
}
