javascript - Display element over text - html,css,js

Question

I want to overlap a ScrollMagic animation on a text, and not make the animation a separate section like it is right here:

There is supposed to be text over there but it made this animation into a new section where the text is at the bottom.

Code:

gsap.registerPlugin(MotionPathPlugin);

const tween = gsap.timeline();
tween.to(".paper-plane", {
  duration: 1,
  ease: "power1.inOut",
  motionPath: {
    path: [
        {x: 100, y: 0},
        {x: 300, y: 10},
        {x: 500, y: 100},
        {x: 750, y: -100},
        {x: 350, y: -50},
        {x: 600, y: 100},
        {x: 800, y: 0},
        {x: window.innerWidth, y: -250}
    ], 
    curviness: 2,
    autoRotate: true
  }
});

const controller = new ScrollMagic.Controller();
const scene = new ScrollMagic.Scene({
triggerElement: '.animation',
duration: 1000,
triggerHook: 0
})
.setTween(tween)
.setPin('.animation')
.addTo(controller);

*{
    margin: 0;
    padding: 0;
    box-sizing: border-box;
}
header, footer{
    height: 100vh;
    display: flex;
    justify-content: center;
    align-items: center;
    font-family: "Montserrat", sans-serif;
}
header h1{
    font-size: 60px;
}
.animation{
    height: 100vh;
    position: relative;
    overflow: hidden;
}
.paper-plane{
    position: absolute;
    top: 50%;
    left: 0%;
}

Answer 1

you need to set the display to absolute

gsap.registerPlugin(MotionPathPlugin);

const tween = gsap.timeline();
tween.to(".paper-plane", {
  duration: 1,
  ease: "power1.inOut",
  motionPath: {
    path: [{
        x: 100,
        y: 0
      },
      {
        x: 300,
        y: 10
      },
      {
        x: 500,
        y: 100
      },
      {
        x: 750,
        y: -100
      },
      {
        x: 350,
        y: -50
      },
      {
        x: 600,
        y: 100
      },
      {
        x: 800,
        y: 0
      },
      {
        x: window.innerWidth,
        y: -250
      }
    ],
    curviness: 2,
    autoRotate: true
  }
});

const controller = new ScrollMagic.Controller();
const scene = new ScrollMagic.Scene({
    triggerElement: '.animation',
    duration: 1000,
    triggerHook: 0
  })
  .setTween(tween)
  .setPin('.animation')
  .addTo(controller)

* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}

header,
footer {
  height: 100vh;
  display: flex;
  justify-content: center;
  align-items: center;
  font-family: "Montserrat", sans-serif;
}

header h1 {
  font-size: 60px;
}

.animation {
  width: 100%;
  height: 800px;
  position: absolute;
  overflow: hidden;
}

.paper-plane {
  position: absolute;
  top: 0;
  left: 0;
}
