    -webkit-animation: buzz-out 1 linear 1.3s;
    -moz-animation: buzz-out 1 linear 1.3s;
    -o-animation: buzz-out 1 linear 1.3s;
    animation: buzz-out 1 linear 1.3s;
}
@-webkit-keyframes buzz-out{10%{-webkit-transform:translateX(3px) rotate(2deg);transform:translateX(3px) rotate(2deg)}20%{-webkit-transform:translateX(-3px) rotate(-2deg);transform:translateX(-3px) rotate(-2deg)}30%{-webkit-transform:translateX(3px) rotate(2deg);transform:translateX(3px) rotate(2deg)}40%{-webkit-transform:translateX(-3px) rotate(-2deg);transform:translateX(-3px) rotate(-2deg)}50%{-webkit-transform:translateX(2px) rotate(1deg);transform:translateX(2px) rotate(1deg)}60%{-webkit-transform:translateX(-2px) rotate(-1deg);transform:translateX(-2px) rotate(-1deg)}70%{-webkit-transform:translateX(2px) rotate(1deg);transform:translateX(2px) rotate(1deg)}80%{-webkit-transform:translateX(-2px) rotate(-1deg);transform:translateX(-2px) rotate(-1deg)}90%{-webkit-transform:translateX(1px) rotate(0);transform:translateX(1px) rotate(0)}100%{-webkit-transform:translateX(-1px) rotate(0);transform:translateX(-1px) rotate(0)}}
