Hello, so I created a new topic regarding my problem. Basically I have a  structure similar to demo in codepen:          What I need is to animate elements inside every section when they appear in the viewport. Now they animate all in the same time. Next question: it is possible in onEnter callback also have an element which trigger onEnter callback?    Thank you for your help. See the Pen RwrYmvR by luk-z-horec (@luk-z-horec) on CodePen &#
