Just noticed that I haven't answered. Sorry for the delay Use cases are when an element needs to be scroll-aware, and the container can be many different elements. Some examples: - Sticky positioning - Load sub elements when element becomes visible in scroll - Animate element when visible in scroll - Pause animations when element is out of sight - Do something when scrolling to bottom scrollParents array for nested scroll-enabled containers might be useful as well, tough it can be easily achieved by recursively calling scrollParent.scrollParent.scrollParent... I prepared one example for a use of scrollParent: https://jsfiddle.net/oriadam/n53asLs2 On Mon, Jun 12, 2017 at 4:41 PM, Mark <mark@heyimmark.com> wrote: > Sounds like a cool feature.
