I am having trouble getting this to behave. I have an animation that is occurring inside of an element that is also being animated (or changed). The issue is that when the outer element changes size, all of the values for the inner animation are not adjusting to the new size. In the codepen you can see this by clicking the start button and then either resize the output window or click the enlarge button to enlarge the outer div. How do you solve this. How do you tell the tween to pay attention to the values if that change? Thanks.
