Inner Overflow Section Scroll Feature

[Sajidul Islam]

Hi all,

Lets say, I have a section and it's total height is 1200px. And I set it's height 100px and use overflow hidden with CSS to hide the other 1100px. My goal is when user scroll to see the other section(below the section I'm talking about) until the remaining 1100px is scrolled. after that people can see the other sections below it.

 

I was able to make a demo, but it not working  properly. Is it possible to achieve my goal using GSAP?

 

 

Please see the video for better understanding.

From your description, it sounds like you need to wrap that scrolling block of text in a parent container and pin everything while it scrolls. Here's a fork of your pen.

Hopefully that helps. Happy tweening.

Hi,

There is a large pin space below that section, Would you be able yo tell me how to fix this issue here?

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:

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.

Hi,

 

If you check Craig's example you'll see this:

gsap.to(".home-banner", {
  yPercent: -100,
  ease: "none",
  scrollTrigger: {
    trigger: ".home-banner", // Element that triggers the animation
    start: "top 45%",
    end: "bottom 45%",
    scrub: 1,
    pin: "#main_scroller_section", // Element pinned in the animation
    markers: true
  }
});

As you can see the element is animated and that triggers the ScrollTrigger instance is different from the element being pinned. That's how you avoid that space you're referring to. Here is how the HTML looks:

<div id="main_scroller_section"> <!-- PINNED ELEMENT -->
  <div class="other-section">Simple Spacer</div>
  <div class="wrapper">
    <div class="home-banner"> <!-- ELEMENT THAT TRIGGERS THE ANIMATION -->
      <!-- CONTENT HERE -->
    </div>
  </div>
  <div class="other-section">Simple Spacer</div>
</div>

Hopefully this clear things up.

Happy Tweening!
