CSS Only 3D Image Slider

A responsive 3D image slider built entirely using radio buttons and CSS3 transforms. There are no graphics used, just basic HTML and CSS.

How to use it:

1. Add images to the label tags and create a set of radio buttons to toggle between those images.

<section id="slider">
  <input type="radio" name="sliderImg" id="s1">
  <input type="radio" name="sliderImg" id="s2">
  <input type="radio" name="sliderImg" id="s3" checked>
  <input type="radio" name="sliderImg" id="s4">
  <input type="radio" name="sliderImg" id="s5">
  <label for="s1" id="slide1">
    <img src="1.jpg" height="100%" width="100%">
  </label>
  <label for="s2" id="slide2">
    <img src="2.jpg" height="100%" width="100%">
  </label>
  <label for="s3" id="slide3">
    <img src="3.webp" height="100%" width="100%">
  </label>
  <label for="s4" id="slide4">
    <img src="4.webp" height="100%" width="100%">
  </label>
  <label for="s5" id="slide5">
    <img src="5.jpg" height="100%" width="100%">
  </label>
</section>

2. The necessary CSS rules to enable the image slider.

[type=radio] {
  display: none;
}
#slider {
  height: 35vw;
  position: relative;
  perspective: 1000px;
  transform-style: preserve-3d;
}
#slider label {
  margin: auto;
  width: 60%;
  height: 100%;
  border-radius: 4px;
  position: absolute;
  left: 0;
  right: 0;
  cursor: pointer;
  transition: transform 0.4s ease;
}
