--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.
assert(new __helpers.CSSHelp(document).getCSSRules('keyframes')?.length === 1);
Your new @keyframes rule should be named wheel.
assert(new __helpers.CSSHelp(document).getCSSRules('keyframes')?.[0]?.name === 'wheel');
