Major beginner needs help with an animation!

Hey I’m trying to rotate a PNG file. I’ve managed to get the item to rotate but only at the beginning of the page thanks to help from someone here.
How do I target the actual element within my page?
This is the code I’m using:

<img class="logo" src="	https://static.showit.co/200/mrKDvB1pTPWw4F5mq2ga7Q/135504/topseller.png">

And

.logo {
  animation: rotation 20s infinite linear;
}

@keyframes rotation {
  from {
    transform: rotate(0deg);
  }

  to {
    transform: rotate(359deg);
  }
}

This is the page:

And this is the item I am trying to target:
