Incorrect site height when I use smooth-scroll with gsap

[btua]

Hi, everyone. I already have website with GSAP animations and I'm trying to connect smooth-scroll library.
When I do it, smooth scroll working, but then doen't work ScrollTrigger and website height incorrect

This is my code

var Scrollbar = window.Scrollbar;

        // Init Smooth Scrollbar
        // ======================
        Scrollbar.init(document.querySelector("#scroll-container"), {
            damping: 0.05,
            renderByPixel: true,
            continuousScrolling: true,
            alwaysShowTracks: true
        });


        // 3rd party library setup
        // More info: https://greensock.com/docs/v3/Plugins/ScrollTrigger/static.scrollerProxy()
        // ========================
        let scrollPositionX = 0,
            scrollPositionY = 0,
            bodyScrollBar = Scrollbar.init(document.getElementById("scroll-container"));

        bodyScrollBar.addListener(({ offset }) => {
            scrollPositionX = offset.x;
            scrollPositionY = offset.y;
        });

        bodyScrollBar.setPosition(0, 0);
        bodyScrollBar.track.xAxis.element.remove();

        // tell ScrollTrigger to use these proxy getter/setter methods for the "body" element:
        ScrollTrigger.scrollerProxy("scroll-container", {
            scrollTop(value) {
                if (arguments.length) {
                    bodyScrollBar.scrollTop = value;
                }
                return bodyScrollBar.scrollTop;
            }
        });

        // when smooth scroller updates, tell ScrollTrigger to update() too. 
        bodyScrollBar.addListener(ScrollTrigger.update);

And then I have height of page

It's pretty tough to troubleshoot without a minimal demo - the issue could be caused by CSS, markup, a third party library, your browser, an external script that's totally unrelated to GSAP, etc. Would you please provide a very simple CodePen or CodeSandbox that demonstrates the issue? 

 

Please don't include your whole project. Just some colored <div> elements and the GSAP code is best (avoid frameworks if possible). See if you can recreate the issue with as few dependancies as possible. If not, incrementally add code bit by bit until it breaks. Usually people solve their own issues during this process! If not, then at least we have a reduced test case which greatly increases your chances of getting a relevant answer.

 

Here's a starter CodePen that loads all the plugins. Just click "fork" at the bottom right and make your minimal demo: 

See the Pen aYYOdN by GreenSock (@GreenSock) on CodePen

 

If you're using something like React/Next/Vue/Nuxt or some other framework, you may find StackBlitz easier to use. We have a series of collections with different templates for you to get started on these different frameworks: React/Next/Vue/Nuxt.

 

Once we see an isolated demo, we'll do our best to jump in and help with your GSAP-specific questions.
