Create Movement Using CSS Animation (Can't Pass)

Tell us what’s happening:

Hi,

I need help to pass this challenge.

Here’s the error message. " The @keyframes rule for 50% should use the left offset of 25px."
I don’t why I’m still getting the message.

Your help will be surely appreciated.

Your code so far


<style>
  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: 0px; 
    left:25px;
  100% {
    background-color: yellow;
    top: 0px;
    left:-25px;
  }
}
</style>

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

You forgot a closing bracket (}) after 50% :wink:

Thank you, my friend. However, I’m not sure if I got it wrong . But does have to look like this? @keyframes rainbow {
0% {
background-color: blue;
top: 0px;
left:0px;
}
50% {
background-color: green;
top: 0px;
left:25px;
}
100% {
background-color: yellow;
top: 0px;
left:-25px;
}
}

Cause it’s still give me the same error, though. :sweat:

Oh I see, it’s because you modified the top property at 50%, just leave it like it was before (top: 50px) and it will work ! :slight_smile:
