Each animation-duration property is paired with a corresponding animation-name property.
If more animation-duration values are declared than corresponding animation-name values, the excess animation-duration values are ignored.
If fewer animation-duration values are declared than corresponding animation-name values, the list of animation-duration values is repeated from the beginning until the animation-name values are exhausted.
