CSS Carousels can be enhanced with scroll-driven animations, allowing animations to trigger as carousel items scroll into view. This technique involves defining keyframes and applying them using the animation-timeline property. While CSS Scroll Snapping is used for smooth scrolling, it can interfere when scroll-based animations are applied. Using view() timelines results in smoother animations but does not resolve the conflict with smooth scrolling.
