Animate.css in hover

See this variant (more interactive):

$(".myDiv").hover(function(){
    $(this).addClass('animated ' + $(this).data('action'));
});
$(".myDiv").bind("animationend webkitAnimationEnd oAnimationEnd MSAnimationEnd",function(){
    $(this).removeClass('animated ' + $(this).data('action'));
});

In your CSS file you could just add:

.questo:hover {
    -webkit-animation: shake 1s;
    animation: shake 1s;
}

The nice thing about this solution is that it requires no JavaScript. For reference look at this page
