So I am working on a fiddle and when I press the on the element to activate the rotation, it no longer changes scale when you hover over it. And you will notice that all of the others change scale just fine. This is what I have for the rotation.
$(C1).click(function() {
$(C1).css("transform", "rotateY(-180deg)");
setTimeout(function() {
$(C1).css("transform", "rotateY(0deg)");
});
