Description : Defining and using `@keyframes` animations in SASS.
Answer :
`@keyframes` is used to create CSS animations inSASS. Define animation steps within `@keyframes` and then apply them using the `animation` property. For example:`@keyframes slideIn { from { transform: translateX(-100%); } to { transform: translateX(0); } } .slide { animation: slideIn 1s ease-out; }` creates a slide-in animation for elements with the `.slide`class.
