# --description--

|
|
|
The `animation-iteration-count` property sets how many times your animation should repeat. This can be set to a number, or to `infinite` to indefinitely repeat the animation. Your Ferris wheel should never stop, so set the `.wheel` selector to have an `animation-iteration-count` of `infinite`.
|
|
|
|
The `animation-timing-function` property sets how the animation should progress over time. There are a few different values for this property, but you want the Ferris wheel animation to run at the same rate from start to finish. Set the `animation-timing-function` to `linear` in your `.wheel` selector.

Your `.wheel` selector should have an `animation-iteration-count` property set to `infinite`.

|
```js
|
|
assert(new __helpers.CSSHelp(document).getStyle('.wheel')?.animationIterationCount === 'infinite');
|

```
