i believe your theme css bypass responsive setting. find your theme css that especially control responsive css. could be in responsive.css. then find setting for:

@media screen and (max-width: 480px) {
  .my {
     display:inline-block
  }
}

and replace to:

@media screen and (max-width: 480px) {
  .my {
     display: block;
  }
}
