Test broken: Change animation timing with keywords

I entered the code correctly and the program actually functioned as it should but the test says it is incorrect. confused by this I watched the video to see what was wrong and my code was identical to that shown in the video.


  .balls {
    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 {
    animation-timing-function: linear;

  #ball2 {
    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>
