Scrolling images in a box

[tomg55555]

Hi there,

It's my first post here I hope I can find some help here since I tried to look everywhere but did not find any solution to my issue.
I'm trying to replicate the effect seen on this website "https://hervebaillargeon.com/", in the section above the landing where when you scroll down some videos are pinned and vertically overlapped. I'm working in a nextjs framework so react based solutions would be awesome but vanilla js it's super fine I'll figure out how to adjust it. As reference I used this codepen:  but what I cannot really understand is how can I implement that in a container which is not scrollable by itself but is content is scrolled and pinned while scrolling the page. Thank you for the help!

i think that's what you looking for,  my demo is an old one so you may find some weird stuff

Thank you so much for your help Rodrigo, as expected I'm having troubles translating this from JS to NextJs. 

 

I'll show you errors I'm getting:

1st:  

end: () => "+=" + cards.length * cards[0].offsetHeight

 

cards[0].offsetHeight, cards is giving me an error.

 

2nd: 

cards.slice(1).forEach((card, i) => {
    tl.fromTo(card, {
        yPercent: 0

 

again card in the middle line is underlined in red.

 

I suppose the problem is at the beginning when I do create the array but I can't really understand what I'm doing wrong here.

 

 

import React, {useEffect, useRef} from 'react';
import {gsap} from 'gsap'
import {ScrollTrigger} from 'gsap/dist/ScrollTrigger'

const Scroller = () => {

    gsap.registerPlugin(ScrollTrigger);
    const component = useRef(null);
    useEffect(() => {

        let ctx = gsap.context(() => {
            // create as many GSAP animations and/or ScrollTriggers here as you want...

            let cards = gsap.utils.toArray(".card");
            console.log(cards.length);
            console.log(cards[0]);
            let tl = gsap.timeline({
                scrollTrigger: {
                    trigger: ".card-wrapper",
                    pin: ".page-wrapper",
                    start: "top top",
                    scrub: true,
                    markers: true,
                    end: () => "+=" + cards.length * cards[0].offsetHeight
                }
            });

            tl.add(() => {
                console.log("card", 1, "in place")
            }, 0.001);

            cards.slice(1).forEach((card, i) => {
                tl.fromTo(card, {
                    yPercent: 0
                }, {
                    yPercent: -100,
                    duration: 0.5
                });
                tl.add(() => {
                    console.log("card", (i+2), "in place");
                })
            })

            gsap.from("h1", { // <- selector text, scoped to this component!
                opacity: 0,
                y: 100,
                ease: "power3",
                duration: 2
            });
        }, component);

    }, []);

    return (
        <div ref={component}>
            <div className="page-wrapper">
                <div className="wrapper">
                    <div className="card-wrapper">
                        <div className="card card-1">
                            1
                        </div>
                        <div className="card card-2">
                            2
                        </div>
                        <div className="card card-3">
                            3
                        </div>
                        <div className="card card-4">
                            4
                        </div>
                        <div className="card card-5">
                            5
                        </div>
                        <div className="card card-6">
                            6
                        </div>
                    </div>
                </div>
            </div>
        </div>

    );
};
export default Scroller;

 

[GSAP Helper]

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 Stackblitz that demonstrates the issue? 

 

Please don't include your whole project. Just some colored <div> elements and the GSAP code is best. 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

 

Using a framework/library like React, Vue, Next, etc.? 

CodePen isn't always ideal for these tools, so here are some Stackblitz starter templates that you can fork and import the gsap-trial NPM package for using any of the bonus plugins: 

• React (please read this article!)
• Next
• Svelte
• Sveltekit
• Vue
• Nuxt

 

Please share the StackBlitz link directly to the file in question (where you've put the GSAP code) so we don't need to hunt through all the files. 

 

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

here it is the stack blitz, I don't know why is working there but not locally on my app.

I was missing the return function of the use effect.

return () => ctx.revert();

Yep.... that happens to the best of us.

 

Great that you found the problem!

 

Happy Tweening!
