Keyframes allow the user to be able to control the element animation a lot more and is another great way to make your longpage more dynamic and interesting.

KEYFRAME ANIMATIONS

In the object animation panel > start animation > Keyframe. Keyframes are similar to timestamps. You set a (key)frame for when you want a specific action. This way you create a path for the element to follow. This path contains keyframes based on the elements position, from a startpoint to endpoint along with rotation and acceleration. Both can be used: based upon time or based upon viewport.

Timeline and viewport keyframe animation

In the object animation panel > scroll > keyframe animation. The element will move across the publication based on the user scrolling in correspondence to the keyframes that have been set by the creator.
