.canvas {

height: 200px;
margin: 50px auto;
background: #fff;
position: relative;
overflow: hidden;
border:1px solid #666;
}

.canvas #ball {
width: 50px;
height: 50px;
background: #999;
position: relative;
border-radius: 50px;
top: 100px;
left : 595px;

animation-name: ball;
animation-iteration-count: 1;
animation-timing-function: ease-in;
animation-duration: 2.0s;

-moz-animation-name: ball;
-moz-animation-iteration-count: 1;
