@keyframes move {
    10%{
        transform: translate(50px,50px)
    }
    30%{
        transform: translate(150px,150px) scale(1.5);
    }
    50%{
        transform: translate(250px,150px) scale(1);
    }
    70%{
        transform: translate(350px,250px) scale(2);
    }
    100%{
        transform: translate(0px,0px) scale(1);
    }
}

@-webkit-keyframes move {
    10%{
        -webkit-transform: translate(50px,50px)
    }
