Counter animation uses ScrollTrigger Library to fire on scroll. Learn more about ScrollTrigger here.
Trigger: the element that will fire the animation on scroll. Use the keyword “this” to use the element itself as the trigger.
Start: determines the position of the Trigger to fire the animation. “top bottom” means when the top of the element hits the bottom of the viewport.
End: determines the end of the animation if needed. It is specially useful when using the Scrub property.

In case you need to fire the animation on additional events.
