# --description--
|
|
|
|
The `@keyframes` at-rule is used to define the flow of a CSS animation. Within the `@keyframes` rule, you can create selectors for specific points in the animation sequence, such as `0%` or `25%`, or use `from` and `to` to define the start and end of the sequence.
|
|
|
|
`@keyframes` rules require a name to be assigned to them, which you use in other rules to reference. For example, the `@keyframes freeCodeCamp { }` rule would be named `freeCodeCamp`.
|
|
|
|
Time to start animating. Create a `@keyframes` rule named `wheel`.
|
|
|
|
# --hints--
|
|
|
|
You should have a `@keyframes` rule.
|
|
|
|
```js
|
|
assert(new __helpers.CSSHelp(document).getCSSRules('keyframes')?.length === 1);
|
|
```
|
|
|
|
Your new `@keyframes` rule should be named `wheel`.
|
|
|
|
```js
|
|
assert(new __helpers.CSSHelp(document).getCSSRules('keyframes')?.[0]?.name === 'wheel');
|
|
```
