No idea what's wrong here

Tell us what’s happening:
I think the size is already 1.5x but it just doesn’t let me through.

  **Your code so far**

<style>
.ball {
  width: 40px;
  height: 40px;
  margin: 50 auto;
  position: fixed;
  background: linear-gradient(
    35deg,
    #ccffff,
    #ffcccc
  );
  border-radius: 50%;
}
#ball1 {
  left: 20%;
}
#ball2 {
  left: 65%;
transform: scale(1.5,1.5);
}


</style>

<div class="ball" id= "ball1"></div>
<div class="ball" id= "ball2"></div>
