From the codepen, I would like to achieve an oscillatory bell movement and although gsap is giving me a lot better than I could achieve on my own with CSS. I plan to read this later. I would like if the bottom tip of the bell doesn't obviously leave the point around the circle its hanging on. I also tried to look through the docs for guides on using rotation, rotationX, etc, but I could only find information on other secondary options for the tween object. I will appreciate a link that documents how primary (x, y, rotation, translate, etc) tween options work. Thank you!
