From Chrome 129, new JavaScript events `scrollSnapChange` and `scrollSnapChanging` enable more precise control over snap targets within scrolling contexts. `scrollSnapChange` fires after the scroll gesture ends and a new snap target is established, while `scrollSnapChanging` fires during the scrolling process when a potential new snap target is determined. These events unlock new possibilities for scroll snap interactions, including animations, linked scrollers, and various UI enhancements.
