</div>

<div class="paper">
<p class="p1">Drag the papers to move!</p>
</div>
<!-- partial -->
  <script  src="./script.js"></script>

</body>
</html>

after that you need to add style.css :

@import url('https://fonts.googleapis.com/css2?family=Zeyada&display=swap');




body {
  height: 100vh;
  display: flex;
  align-items: center;
  justify-content: center;

  background-size: 1000px;
  background-image: url("https://www.psdgraphics.com/wp-content/uploads/2022/01/white-math-paper-texture.jpg");
  background-position: center center;
}

.paper {
  background-image: url("https://i0.wp.com/textures.world/wp-content/uploads/2018/10/2-Millimeter-Paper-Background-copy.jpg?ssl=1");
  background-size: 500px;
  background-position: center center;
  padding: 20px 100px;
  //min-width: 800px;
  
  transform: rotateZ(-5deg);
  box-shadow: 1px 15px 20px 0px rgba(0,0,0,0.5);
  
  position: absolute;
}

.paper.heart {
  position: relative;
  width: 200px;
  height: 200px;
  padding: 0;
  border-radius: 50%;
}

.paper.image {
  padding: 10px;
}
.paper.image p {
  font-size: 30px;
}

img {
  max-height: 200px;
  width: 100%;
  user-select: none;
}

.paper.heart::after {
  content: "";
  background-image: url('https://cdn.pixabay.com/photo/2016/03/31/19/25/cartoon-1294994__340.png');
  width: 100%;
  height: 100%;
  position: absolute;
  top: 0;
  left: 0;
  background-size: 150px;
  background-position: center center;
  background-repeat: no-repeat;
  opacity: 0.6;
}

.paper.red {
/*   filter: hue-rotate(90deg); */
}
.paper:nth-of-type(3n) {
  background-position: left top;
}
.paper:nth-of-type(3n) {
/*   filter: hue-rotate(200deg); */
}

p {
  font-family: 'Zeyada';
  font-size: 50px;
  color: rgb(0,0,100);
  opacity: 0.75;
  user-select: none;
  
  // filter: drop-shadow(2px 1.5px 1px rgba(0,0,105,0.9));
}

after that the most important part adding javascript :If you want to work this effect on mobile use script.js for mobile :script.js (Mobile ) :

let highestZ = 1;
class Paper {
  holdingPaper = false;
  touchStartX = 0;
  touchStartY = 0;
  touchMoveX = 0;
  touchMoveY = 0;
  touchEndX = 0;
  touchEndY = 0;
  prevTouchX = 0;
  prevTouchY = 0;
  velX = 0;
  velY = 0;
  rotation = Math.random() * 30 - 15;
  currentPaperX = 0;
  currentPaperY = 0;
  rotating = false;
  init(paper) {
    paper.addEventListener("touchmove", (e) => {
      e.preventDefault();
      if (!this.rotating) {
        this.touchMoveX = e.touches[0].clientX;
        this.touchMoveY = e.touches[0].clientY;
        this.velX = this.touchMoveX - this.prevTouchX;
        this.velY = this.touchMoveY - this.prevTouchY;
      }
      const dirX = e.touches[0].clientX - this.touchStartX;
      const dirY = e.touches[0].clientY - this.touchStartY;
      const dirLength = Math.sqrt(dirX * dirX + dirY * dirY);
      const dirNormalizedX = dirX / dirLength;
      const dirNormalizedY = dirY / dirLength;
      const angle = Math.atan2(dirNormalizedY, dirNormalizedX);
      let degrees = (180 * angle) / Math.PI;
      degrees = (360 + Math.round(degrees)) % 360;
      if (this.rotating) {
        this.rotation = degrees;
      }
      if (this.holdingPaper) {
        if (!this.rotating) {
          this.currentPaperX += this.velX;
          this.currentPaperY += this.velY;
        }
        this.prevTouchX = this.touchMoveX;
        this.prevTouchY = this.touchMoveY;
        paper.style.transform = `translateX(${this.currentPaperX}px) translateY(${this.currentPaperY}px) rotateZ(${this.rotation}deg)`;
      }
    });
    paper.addEventListener("touchstart", (e) => {
      if (this.holdingPaper) return;
      this.holdingPaper = true;
      paper.style.zIndex = highestZ;
      highestZ += 1;
      this.touchStartX = e.touches[0].clientX;
      this.touchStartY = e.touches[0].clientY;
      this.prevTouchX = this.touchStartX;
      this.prevTouchY = this.touchStartY;
    });
    paper.addEventListener("touchend", () => {
      this.holdingPaper = false;
      this.rotating = false;
    });
    // For two-finger rotation on touch screens
    paper.addEventListener("gesturestart", (e) => {
      e.preventDefault();
      this.rotating = true;
    });
    paper.addEventListener("gestureend", () => {
      this.rotating = false;
    });
  }
}
const papers = Array.from(document.querySelectorAll(".paper"));
papers.forEach((paper) => {
  const p = new Paper();
  p.init(paper);
});

script.js ( Pc or Desktop ):
let highestZ = 1;

class Paper {
  holdingPaper = false;
  mouseTouchX = 0;
  mouseTouchY = 0;
  mouseX = 0;
  mouseY = 0;
  prevMouseX = 0;
  prevMouseY = 0;
  velX = 0;
  velY = 0;
