$('#arrowBtn').on('mouseleave', (e)=>{ gsap.to('.arrow', {y:0, duration:0.5, ease:'power3.out', overwrite:'auto'}); })
$('#arrowBtn').on('click', (e)=>{ gsap.to(window, {scrollTo:innerHeight, duration:1.5, ease:'power1.inOut'}); }) // scrollTo requires the ScrollTo plugin (not to be confused w/ ScrollTrigger)
