Challenge: Learn CSS Animation by Building a Ferris Wheel - Step 20

Link to the challenge:

The value of animation-name should match the name of the keyframes you created at the end of the CSS.

Then you would add the animation-duration property on a separate line.

@Sujka
you will add
animation-name: wheel;
animation-duration: 10s;
on separate line line in .wheel
