You can use `@keyframes`inSASS just as you would in regular CSS. Define the animation with`@keyframes` and then use it within a mixin or directly in your styles. For example:`@keyframes slide { from { transform: translateX(-100%); } to { transform: translateX(0); } } .slider { animation: slide 0.5s ease-in-out; }` applies a slide-in animation.
