I don’t know what a heck am I doing wrong here! Could anyone help me here please!

Your code so far

  div {
    height: 40px;
    width: 70%;
    background: black;
    margin: 50px auto;
    border-radius: 5px;
    position: relative;

#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;
    left: -25px;

<div id="rect"></div>

Link to the challenge:

You should only deal with the left offset, why did you modify the top offset at 50% and 100%, you have done the left offsets in a correct way, but you shouldn’t modify the top offsets, reset only the top offsets at 50 and 100% to old value
