Hello I'm using TweenMax with scrollmagic. I was hoping to have my top: 200px, change dynamically based on the size of the browser, so something like $('#container-div).position().top * 1.2 instead of 200px Is this possible? Thanks very much var controller = new ScrollMagic(); var seq = new TimelineMax() .add(TweenMax.to("#top-text-container", 100, {top: "200px", force3D:true})) new ScrollScene({ duration:2800, }).setTween(seq) .addTo(controller);
