Systems and methods for visually creating scroll-triggered animation in a document. Based on input received, a key position is determined that is associated with an element that is to be animated. An indicator may be displayed to visually show the location of the key position on an editing canvas. A scroll-triggered animation is defined for the element based on the specified key position. The scroll-triggered animation defines attributes of the element during scroll of the document in the end use environment. For example, the animation may specify that the element has a particular location when the scroll is at the specified key position. The scroll-triggered animation may additionally or alternatively comprise a before-effect and an after-effect, performing one animation before the scroll reaches the key position and another animation after the scroll reaches the key position.
