Without a minimal demo, it's very difficult to troubleshoot; the issue could be caused by CSS, markup, a third party library, a 3rd party script, etc. Would you please provide a very simple CodePen or Stackblitz that illustrates 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. Start minimal and then incrementally add code bit by bit until it breaks. Usually people solve their own issues during this process! If not, at least we have a reduced test case which greatly increases your chances of getting a relevant answer.

 

 

that loads all the plugins. Just click "fork" at the bottom right and make your minimal demo: 

 

 

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. ✅

Thank you, i just add the minimal demo but using stackblitz

[Create gsap simple animation for each slide with swiper everytime the slider change]

it's very hard to tell without a minimal demo.

it sounds like you might just be animating it to 100 multiple times which won't show any change if the y is already at 100.

make sure you are increasing the y value by 100 each time.

This can be done using the relative string syntax y:"+=100"

 

gsap.to(something, {y:"+=100"})

 

 

 

you right, i need to edit my question

[UPDATE]: QUESTION UPDATED

[Create gsap simple animation for each slide with swiper everytime the slider change]

I tried creating a simple animation for each slide whenever the slider changes. For example, just adding y: 100px to it. However, when I added GSAP onSlideChange, it work just for the first time and the other slides didn't animate; instead, they got stuck at y: 100px.

demo: https://stackblitz.com/edit/swiper-react-saklce?file=src%2FApp.js

<Swiper
  slidesPerView={1}
  onSlideChange={e => {
    gsap.to(".swiper-slide-active .hero-cta", {
      y: "100%"
    })
  }}
  loop
>
  <SwiperSlide>
    <button className="hero-cta">slide 1</button
  </SwiperSlide>
  <SwiperSlide>
    <button className="hero-cta">slide 1</button
  </SwiperSlide>
</Swiper>

my expected, each button get animated everytime the slide change, thanks in advance

[Extra whitespace from pin-spacer]

 

I've been experimenting with GSAP for the past few weeks using next, and I've been trying to use "pin" with "scrollTrigger." However, it seems like I'm getting extra white space every time I use "pin" with the scroll trigger. Is there something wrong with my code? 

first, I create two refs.

const animatedPath = useRef(null)
const svgref = useRef(null)

 

and second I use `useLayoutEffect` for register scroll trigger plugin and define gasp animation

useLayoutEffect(() => {
  gsap.registerPlugin(ScrollTrigger)

  const tl = gsap.timeline({
    scrollTrigger: {
      trigger: svgref.current,
      start: "top top",
      end: "bottom 100",
      scrub: true,
      markers: true,
      pin: true
    }
  })

  gsap.set(animatedPath.current, {
    strokeDasharray: 471.2,
    strokeDashoffset: 471.2,
  })

  tl.to(animatedPath.current, {
    strokeDashoffset: 0
  })
}, [])

after that, i create svg with circle inside it

<section style={{ height: "200vh" }}>
  <svg ref={svgref} style={{ width: "400px", height: "400px" }} xmlns="http://www.w3.org/2000/svg">
    <circle cx={200} cy={200} r={75} fill="none" stroke="black" strokeWidth={10} ref={animatedPath} />
  </svg>
</section>

The result shows that the `pin-spacer` class has a large padding/whitespace, and the animation doesn't start properly.
