@171h/scroll-sync v0.0.1

Scroll Sync

Scroll synchronization (scroll-sync), which associates multiple elements with scroll properties (overflow: scroll). When a scroll event occurs in one of the elements, the scroll effect is mapped to all the elements associated with it. To achieve synchronization purposes. scroll-sync supports fixed synchronization (px) and relative synchronization (%).

Acknowledgements

This is a rewrite of scroll-sync with typescript and added some new features liking scroll-sync only by x or y.
