Horizontal Scroll with Sticky Panels Effect

[ssaruh 1 Likes (Newbie)]

Hi! I'm trying to achieve an effect similar to https://gallery.delivery/ or https://shadow-brand.com/, where there is horizontal scrolling but the sections stick to the left side of the page so that the next section overlaps it.

 

 

Here is my pen:

 

I've achieved the horizontal scrolling effect looking at other threads here, but not sure how to approach the stickiness aspect-- I've tried applying a class that would fix the position of the panels but that removes them from the flow and causes things to jump around. Are you able to horizontally pin each element as it reaches the left side of the screen? Haven't seen any examples of this. Not expecting anyone to solve the whole thing for me but if anyone could point me in the right direction or could suggest a method of doing this it would be super helpful!

 

Thanks!

Hi @ssaruh and welcome to the GreenSock forums!

 

This is more related to the way the elements are animated. In this case you have to move each card it's own width times the card's index in the collection and the duration of each animation has to increase based on the same index. For that you can use function based values:

let scrollTween = gsap.to(sections, {
  xPercent: (i) => -100 * i,
  duration: (i) => 0.5 * i,
  ease: "none", // <-- IMPORTANT!
  scrollTrigger: {
    trigger: ".container",
    pin: true,
    markers: true,
    scrub: 0.1,
    //snap: directionalSnap(1 / (sections.length - 1)),
    end: "+=3000 bottom"
  }
});

Unfortunately the container animation class toggle functionality goes a bit wonky and it doesn't work as expected:

You'll have to come up with a different custom logic to toggle that class, based on the progress of the ScrollTrigger instance on scrollTween. I tinkered with it quite a bit and couldn't come up with something solid and I don't have a lot of time to go through this right now.

 

Let us know if you have more questions.

Happy Tweening!

Thank you so much! This achieved the main effect I was looking for.

 

The only other thing I added was a conditional statement so that the last panel doesn't scroll all the way to the left, + making it responsive so it switches to a vertical scroll under 767px window.
