Q
How does the animation-fill-mode property impact the appearance of elements before and after a keyframe animation?

Answer & Solution

Answer: Option D
Solution:
The animation-fill-mode property in CSS keyframe animations impacts the appearance of elements before and after a keyframe animation by defining how the element's styles should be applied before (backwards) and after (forwards) the animation. By specifying backwards, the element applies the styles of the starting keyframe before the animation begins, and by specifying forwards, the element retains the styles of the ending keyframe after the animation ends, ensuring a smooth transition in appearance.
