3D Rotator Gallery In Pure CSS

A creative, automatic, CSS only photo gallery that rotates through images in a 3D space.

How to use it:

1. Add images to the rotator gallery.

<div class="rotator">
  <div class="items">
    <img src="1.jpg" alt="Image Alt" />
  </div>
  <div class="items">
    <img src="2.jpg" alt="Image Alt" />
  </div>
  <div class="items">
    <img src="3.jpg" alt="Image Alt" />
  </div>
  <div class="items">
    <img src="4.jpg" alt="Image Alt" />
  </div>
  <div class="items">
    <img src="5.jpg" alt="Image Alt" />
  </div>
  <div class="items">
    <img src="6.jpg" alt="Image Alt" />
  </div>
  <div class="items">
    <img src="7.jpg" alt="Image Alt" />
  </div>
  <div class="items">
    <img src="8.jpg" alt="Image Alt" />
  </div>
  <div class="items">
    <img src="9.jpg" alt="Image Alt" />
  </div>
</div>

2. The core styles for the rotator gallery.

.rotator {
  position: absolute;
  left: 0;
  right: 0;
  margin: auto;
  width: 55%;
  height: 150px;
  transform-style: preserve-3d;
  animation: roter 17s linear infinite;
}
.rotator:hover {
  animation-play-state: paused;
}
@keyframes roter {
  from {
    transform: rotateY(0deg);
  }
  to {
    transform: rotateY(360deg);
  }
}
.items {
  position: absolute;
  height: 100%;
  width: 100%;
  overflow: hidden;
  border: 2px solid #333;
}
.items:hover img {
  transform: scale(1.2);
}
.items img {
  height: 100%;
  width: 100%;
  transition: all 3s ease;
}

3. Determine the initial position for each image. That’s it.

.items:first-child {
  transform: rotateY(calc(40deg * 1)) translateZ(300px);
}
.items:nth-child(2) {
  transform: rotateY(calc(40deg * 2)) translateZ(300px);
}
.items:nth-child(3) {
  transform: rotateY(calc(40deg * 3)) translateZ(300px);
}
.items:nth-child(4) {
  transform: rotateY(calc(40deg * 4)) translateZ(300px);
}
.items:nth-child(5) {
  transform: rotateY(calc(40deg * 5)) translateZ(300px);
}
.items:nth-child(6) {
  transform: rotateY(calc(40deg * 6)) translateZ(300px);
}
.items:nth-child(7) {
  transform: rotateY(calc(40deg * 7)) translateZ(300px);
}
.items:nth-child(8) {
  transform: rotateY(calc(40deg * 8)) translateZ(300px);
}
.items:nth-child(9) {
  transform: rotateY(calc(40deg * 9)) translateZ(300px);
}
