Thanks for the patience.
Trying to simplify:
https://codepen.io/nelson-velasco/pen/wvydaby
1. I made a Gsap timeline that goes from point A to point B
2. Point B is associated with the width of a specific div
3. This div can vary in width (resize)
4. Then I associate the movement to the width of that div as follows:
.to(icon_advance,{ left: myDiv.offsetWidth, })
5. The Gsap timeline doesn't adjust to the new width, or I don't know how to do it.
Again i appreciate any response
