Hello Santiago,

The best way of doing is this:

  1. Add a div-block ‘scroll-tracker-container’ and make it absolute, position it to the top of the page.
  2. Add a second div-block inside that container ‘tracker’ and make it absolute as well but to cover the whole container.
  3. Using animations ‘While page scrolling’ make that tracker 0% when the page is at the top and 100% when the page is at the bottom.

Let me know if this makes sense.
