I there a way to decrease font size as a page scrolls

Recommended Posts

I am new and am not sure what to use, I have the full gsap package.  What I want is a static menu that get smaller as you scroll the page down. (CampfirePixels)  I can always do it with css and breakpoints, but I wanted to do it with JavaScript if I can.  See https://d.pr/i/YtUG7r.

Hey dgs. Welcome and thanks for being a Club GreenSock member!


There's a few different ways to do this sort of animation. The way that I would do it is something along the lines of this:


var tl = new TimelineMax({paused:true})
tl.to(".box", 1, {"scale": 0.3})

var maxDistance = 400;

window.addEventListener("scroll", function() {
  var yPos = window.scrollY;
  tl.progress(yPos / maxDistance);

See the Pen BaBpELw?editors=0010 by GreenSock (@GreenSock) on CodePen


I'm happy to explain any part of this if you're having any trouble!
