Change Listview icons size

The size of Listview icons is 16px. But often I wish show bigger size icons. So I wrote some css.

.ui-listview .ui-li-icon {
  position: absolute !important;
  max-height: 24px !important;
  max-width: 24px !important;
  left: 10px !important;
  top: 10px !important;
}

16px

24px
