What is wrong here.. I am not able to understand

Tell us what’s happening:

  **Your code so far**


  border-radius: 50%;
  background: linear-gradient(
  position: fixed;
  width: 50px;
  height: 50px;
  margin-top: 50px;
  animation-name: bounce;
  animation-duration: 2s;
  animation-iteration-count: infinite;
#ball1 {
  left: 27%;
  animation-timing-function: cubic-bezier (0.25, 0.25, 0.75, 0.75);
#ball2 {
  left: 56%;
  animation-timing-function: ease-out;

@keyframes bounce {
  0% {
    top: 0px;
  100% {
    top: 249px;


<div class="balls" id="ball1"></div>
<div class="balls" id="ball2"></div>
