3D Card

This project is a project that implements a 3D card using CSS.

CSS

.card:hover .wrapper {
  transform: perspective(900px) translateY(-5%) rotateX(25deg) translateZ(0);
  box-shadow: 2px 35px 32px -8px rgba(0, 0, 0, 0.75);
  -webkit-box-shadow: 2px 35px 32px -8px rgba(0, 0, 0, 0.75);
  -moz-box-shadow: 2px 35px 32px -8px rgba(0, 0, 0, 0.75);
}

3D Carousel

This project is a project that implements the image carousel effect using CSS and JavaScript.

Start Effect

for (var i = 0; i < imgs.length; i++) {
    imgs[i].style.transform = "rotateY(" + i * (360 / imgs.length) + "deg) translateZ(" + radius + "px)";
    imgs[i].style.transition = "transform 1s";
    imgs[i].style.transitionDelay = delayTime || (imgs.length - i) / 4 + "s";
  }

Image 3D Effect

img {
  transform-style: preserve-3d;
  position: absolute;
  left: 0;
  top: 0;
  width: 100%;
  height: 100%;
  line-height: 200px;
  font-size: 50px;
  text-align: center;
  box-shadow: 0 0 8px #fff;
  -webkit-box-reflect: below 10px linear-gradient(transparent, transparent, #0005);
}

Mouse Event Effect

document.onpointerdown = function (e) {
  clearInterval(wheel.timer);
  e = e || window.event;
  var sX = e.clientX, sY = e.clientY;

  this.onpointermove = function (e) {
    e = e || window.event;
    var nX = e.clientX, nY = e.clientY;
    desX = nX - sX;
    desY = nY - sY;
    tX += desX * 0.1;
    tY += desY * 0.1;
    applyTransform(wheel);
    sX = nX;
    sY = nY;
  };

  this.onpointerup = function (e) {
    wheel.timer = setInterval(function () {
      desX *= 0.95;
      desY *= 0.95;
      tX += desX * 0.1;
      tY += desY * 0.1;
      applyTransform(wheel);
      playSpin(false);
      if (Math.abs(desX) < 0.5 && Math.abs(desY) < 0.5) {
        clearInterval(wheel.timer);
        playSpin(true);
      }
    }, 17);
    this.onpointermove = this.onpointerup = null;
  };

  return false;
};

3D Card Hover

This project shows 3D animation using characters.

Caption Animation

figcaption {
  grid-area: 1/1;
  width: calc(100% + 40px);
  font-family: Exoct;
  color: white;
  font-size: min(32px, 5vmin);
  text-align: center;
  place-self: end center;
  transform: perspective(500px) translateY(100%) rotateX(-90deg);
  backface-visibility: hidden;
  transform-origin: top;
  background: #000;
  transition: 0.5s;
}

Image Effect

figure {
  width: 100%;
  aspect-ratio: 1;
  margin: 0 0 60px;
  padding: 5px 20px 0;
  box-sizing: border-box;
  display: grid;
  grid-template-rows: 100%;
  cursor: pointer;
  position: relative;
  filter: drop-shadow(0 0 20px rgb(0 0 0/50%));
}

figure:before {
  background-image: url(https://assets.codepen.io/1480814/necro-back.jpg);
}

figure + figure:before {
  background-image: url(https://assets.codepen.io/1480814/druid-bac.jpg);
}

3D Card Effect

This project is a project that shows a 3D card using mouse events.

Add mouse event listener

container.addEventListener("mousemove", (e) => {
  let X = (window.innerWidth / 2 - e.pageX) / 30;
  let Y = (window.innerHeight / 2 - e.pageY) / 30;

  card.style.transition = "none";
  card.style.transform = `rotateX(${X}deg) rotateY(${Y}deg)`;
});

3D Card Effect V2

Mouse Event

window.addEventListener("DOMContentLoaded", (event) => {
  const cards = document.querySelectorAll(".card");
  cards.forEach((e) => {
    e.addEventListener("mousemove", (event) => {
      const rect = e.getBoundingClientRect();
      const centerX = (rect.left + rect.right) / 2;
      const centerY = (rect.top + rect.bottom) / 2;
      const posX = event.pageX - centerX;
      const posY = event.pageY - centerY;
      const x = remap(posX, rect.width / 2, angle);
      const y = remap(posY, rect.height / 2, angle);
      e.dataset.rotateX = x;
      e.dataset.rotateY = -y;
    });

    e.addEventListener("mouseout", (event) => {
      e.dataset.rotateX = 0;
      e.dataset.rotateY = 0;
    });
  });

  const update = () => {
    cards.forEach((e) => {
      let currentX = parseFloat(
        e.style.getPropertyValue("--rotateY").slice(0, -1)
      );
      let currentY = parseFloat(
        e.style.getPropertyValue("--rotateX").slice(0, -1)
      );
      if (isNaN(currentX)) currentX = 0;
      if (isNaN(currentY)) currentY = 0;
      const x = lerp(currentX, e.dataset.rotateX, 0.05);
      const y = lerp(currentY, e.dataset.rotateY, 0.05);
      e.style.setProperty("--rotateY", x + "deg");
      e.style.setProperty("--rotateX", y + "deg");
    });
  };
  setInterval(update, 1000 / 60);
});
