/*If you want a css only solution you can use active*/
.crossRotate:active {
transform: rotate(45deg);
-webkit-transform: rotate(45deg);
-ms-transform: rotate(45deg);
}
/*But the transformation will not persist when the activity moves.
For that you need javascript (jquery click and css is the cleanest IMO).*/
