CSS Only Infinite Carousel

Preview:

Description:

A simple infinitely looping carousel built on top of plain HTML and CSS/CSS3.

How to use it:

1. Wrap your carousel items into label elements as follows:

<div class="myCarousel">
  <label class="item" for="t-1">
    <img src="1.jpg" alt="picture">
    Carousel Item 1
  </label>
  <label class="item" for="t-2">
    <img src="2.jpg" alt="picture">
    Carousel Item 2
  </label>
  <label class="item" for="t-3">
    <img src="3.jpg" alt="picture">
    Carousel Item 3
  </label>
  ...
</div>

2. Create a group of radio buttons to switch between those carousel items.

<input type="radio" name="carousel" id="t-1">
<input type="radio" name="carousel" id="t-2">
<input type="radio" name="carousel" id="t-3" checked>
...

3. Add a pagination control to the bottom of the carousel. The full HTML structure should be like these:

<div class="slider">
  <input type="radio" name="carousel" id="t-1">
  <input type="radio" name="carousel" id="t-2">
  <input type="radio" name="carousel" id="t-3" checked>
  <input type="radio" name="carousel" id="t-4">
  <input type="radio" name="carousel" id="t-5">
  <div class="myCarousel">
    <label class="item" for="t-1">
      <img src="1.jpg" alt="picture">
      Carousel Item 1
    </label>
    <label class="item" for="t-2">
      <img src="2.jpg" alt="picture">
      Carousel Item 2
    </label>
    <label class="item" for="t-3">
      <img src="3.jpg" alt="picture">
      Carousel Item 3
    </label>
    <label class="item" for="t-4">
      <img src="4.jpg" alt="picture">
      Carousel Item 4
    </label>
    <label class="item" for="t-5">
      <img src="5.jpg" alt="picture">
      Carousel Item 5
    </label>
  </div>
  <div class="dots">
    <label for="t-1"></label>
    <label for="t-2"></label>
    <label for="t-3"></label>
    <label for="t-4"></label>
    <label for="t-5"></label>
  </div>
</div>

4. The core CSS styles for the carousel.

.slider {
  width: 100%;
}
.slider input {
  display: none;
}
.myCarousel {
  display: flex;
  align-items: center;
  justify-content: center;
  position: relative;
  min-height: 350px;
  perspective: 1000px;
  overflow: hidden;
}
.myCarousel .item {
  width: 450px;
  padding: 30px;
  border-radius: 5px;
  background-color: #0A0220;
  position: absolute;
  top: 0;
  box-sizing: border-box;
  text-align: center;
  transition: transform 0.4s;
  box-shadow: 0 0 10px rgba(0,0,0,0.3);
  user-select: none;
  cursor: pointer;
}
.myCarousel .item img {
  width: 100px;
  height: 100px;
  object-fit: cover;
  border-radius: 50%;
  border: 13px solid #3B344D;
}
.dots {
  display: flex;
  justify-content: center;
  align-items: center;
}
.dots label {
  height: 5px;
  width: 5px;
  border-radius: 50%;
  cursor: pointer;
  background-color: #413B52;
  margin: 7px;
  transition-duration: 0.2s;
}

5. Activate the carousel using the radio button CSS hacks.

#t-1:checked ~ .dots label[for="t-1"],
#t-2:checked ~ .dots label[for="t-2"],
#t-3:checked ~ .dots label[for="t-3"],
#t-4:checked ~ .dots label[for="t-4"],
#t-5:checked ~ .dots label[for="t-5"] {
  transform: scale(2);
  background-color: #fff;
}
#t-1:checked ~ .dots label[for="t-2"],
#t-2:checked ~ .dots label[for="t-1"],
#t-2:checked ~ .dots label[for="t-3"],
#t-3:checked ~ .dots label[for="t-2"],
#t-3:checked ~ .dots label[for="t-4"],
#t-4:checked ~ .dots label[for="t-3"],
#t-4:checked ~ .dots label[for="t-5"],
#t-5:checked ~ .dots label[for="t-4"] {
  transform: scale(1.5);
}
#t-1:checked ~ .myCarousel label[for="t-3"],
#t-2:checked ~ .myCarousel label[for="t-4"],
#t-3:checked ~ .myCarousel label[for="t-5"],
#t-4:checked ~ .myCarousel label[for="t-1"],
#t-5:checked ~ .myCarousel label[for="t-2"] {
  transform: translate3d(600px, 0, -180px) rotateY(-25deg);
  z-index: 2;
}
#t-1:checked ~ .myCarousel label[for="t-2"],
#t-2:checked ~ .myCarousel label[for="t-3"],
#t-3:checked ~ .myCarousel label[for="t-4"],
#t-4:checked ~ .myCarousel label[for="t-5"],
#t-5:checked ~ .myCarousel label[for="t-1"] {
  transform: translate3d(300px, 0, -90px) rotateY(-15deg);
  z-index: 3;
}
#t-2:checked ~ .myCarousel label[for="t-1"],
#t-3:checked ~ .myCarousel label[for="t-2"],
#t-4:checked ~ .myCarousel label[for="t-3"],
#t-5:checked ~ .myCarousel label[for="t-4"],
#t-1:checked ~ .myCarousel label[for="t-5"] {
  transform: translate3d(-300px, 0, -90px) rotateY(15deg);
  z-index: 3;
}
#t-3:checked ~ .myCarousel label[for="t-1"],
#t-4:checked ~ .myCarousel label[for="t-2"],
#t-5:checked ~ .myCarousel label[for="t-3"],
#t-2:checked ~ .myCarousel label[for="t-5"],
#t-1:checked ~ .myCarousel label[for="t-4"] {
  transform: translate3d(-600px, 0, -180px) rotateY(25deg);
}
#t-1:checked ~ .myCarousel label[for="t-1"],
#t-2:checked ~ .myCarousel label[for="t-2"],
#t-3:checked ~ .myCarousel label[for="t-3"],
#t-4:checked ~ .myCarousel label[for="t-4"],
#t-5:checked ~ .myCarousel label[for="t-4"],
#t-5:checked ~ .myCarousel label[for="t-5"] {
  z-index: 4;
}
