Hello! How can I connect animation through a bookmark (anchor), on a third-party js, so that it works in a certain place on the page?

Maybe this will be helpful?

Thanks for the quick response! But the question is different. There are ready-to-use Java scripts. How can they be launched only when scrolling in a certain place on the page? Thank!

You cannot trigger ready-to-use Java scripts via events.
