Opacity behavior of the "Down page" button when scrolling

[VictorKrs]

Hello users, WWW!

I can't get the "Down page" button to display correctly.
In the project, following the link ( https://docs.google.com/document/d/1ONQ ... ue&sd=true ), the "Up page" button is displayed correctly (100% opacity appears when scrolling the page slightly and persists until scrolling to the end of the page). The opacity behavior of the "Down page" button would like to have the same, but the opposite is true (that is, the opacity of 100% remains when scrolling almost to the end of the page and begins to decrease to "0" at the same distance to the end of the page as the "Down page" button, but from the beginning of the page). I've tried many settings, read the help, studied the demo project, but it doesn't work out as needed! I spent a lot of time ☹

Please help me!


Yours sincerely, Victor

I think your logic is wrong.

The 'end' offset should be a positive value (250 instead of -250) and the opacity should be 1 instead of 0

Thank you for the decision, Pablo!

Yes, I misunderstand the logic, it's obvious!
I need to dive into the question and figure it out!

Yours sincerely, Victor
