Tell us what’s happening:

Your code so far


<style>
  div {
    height: 40px;
    width: 70%;
    background: black;
    margin: 50px auto;
    border-radius: 5px;
    position: relative;
    horizontal: left;
  }

#rect {
  animation-name: rainbow;
  animation-duration: 4s;
}

@keyframes rainbow {
  0% {
    background-color: blue;
    top: 0px;
    left: 0px;
  }
  50% {
    background-color: green;
    top: 25px;
    left: 25px;
  }
  100% {
    background-color: yellow;
    top: -25px;

So I don’t really see a reason why the animation shouldn’t work.
But if it’s your test crashing… There’s a simple solution for that.

The exercise askes you not to change the top values:

has to be 50px on 50%
and 0px at 100%

what is the solution please?

Use the values for top in the keyframe declaration that were given to you in the exercise. Like below:

  0% {
    background-color: blue;
    top: 0px;
    
  }
  50% {
    background-color: green;
    top: 50px;
    
  }
  100% {
    background-color: yellow;
    top: 0px;
    
  }
}
