Scrollama – Scrollytelling with IntersectionObserver

Scrollama is a modern & lightweight JavaScript library for scrollytelling using IntersectionObserver in favor of scroll events.

The code that accompanies the markup pictured above:

// instantiate the scrollama
const scroller = scrollama();

// setup the instance, pass callback functions
scroller
  .setup({
    container: '.scroll', // wrapping container
    step: '.scroll__text .step', // all steps
    graphic: '.scroll__graphic', // the sticky element
    offset: 0.5, // optional, default = 0.5
  })
  .onStepEnter(handleStepEnter)
  .onStepExit(handleStepExit)
  .onContainerEnter(handleContainerEnter)
  .onContainerExit(handleContainerExit);
