JavaScript scroll snap events for scroll-triggered animations

Chrome 129 and above now supports new scroll snap events, scrollsnapchange and scrollsnapchanging, enhancing the dynamic control over CSS scroll snap features. These events allow developers to track and style elements as they transition to new snap targets, with scrollsnapchanging triggered during a scroll movement predicting potential targets, and scrollsnapchange fired once a target is locked post-scroll. Implementations of these events demonstrate their utility in creating interactive features like animated carousels, auto-playing video trailers, and dynamic storytelling experiences. By combining these JavaScript events with CSS snap properties, a seamless scrolling experience is achieved, surpassing the capabilities of the Intersection Observer API, which lacks real-time updates. Despite limited browser support currently confined to Chrome and Edge, these events present a significant step forward in integrating JavaScript-driven dynamics with CSS snapping, offering developers new avenues for creative and functional design.
