.animation{
width: 100px;
height: 100px;
border-radius: 50px;
background-color: #dd3456;
animation-name: up_down;
animation-delay: 0ms;
animation-duration: 2s;
animation-timing-function: ease-in;
animation-iteration-count: infinite;
}
@keyframes up_down {
0%{
transform: translateY(10px);
}
50%{
transform: translateY(0px);
}
100%{
transform: translateY(10px);
}
}
