Q
What is the purpose of using keyframes in CSS animations?

Answer & Solution

Answer: Option A
Solution:
The purpose of using keyframes in CSS animations is to define the starting and ending states of an animation. Keyframes allow developers to specify intermediate style changes at different points along the animation timeline (e.g., 0%, 50%, 100%), enabling complex movements, transformations, and sequences of style changes that contribute to dynamic and engaging animations on web pages.
