CSS @keyframes and animation Properties Work

HTML-CSS

Everything looks correct to me…what am I overlooking???

Your code so far


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

  #rect {
  #anim {
    animation-name: rainbow;
    animation-duration: 4s;
  }
  @keyframes rainbow { 
    0% {
      background-color: blue;
    }
    50% {
      background-color: green;
    }
    100% {
      background-color: yellow;
    }
  }
  
  
  
  
</style>
<div id="rect"></div>

Look at your selector:

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

You should only target the element with an id of rect. I guess you copied the example code and didn’t change it fully.
