Understanding Keyframes
What are Keyframes?
Keyframes define specific points in an animation sequence. They specify what styles an element should have at particular moments during the animation timeline.
@keyframes animationName {
0% { /* start state */ }
50% { /* middle state */ }
100% { /* end state */ }
