CSS Only Cross-fading Image Slideshow

Description:

A simple image slideshow implemented in pure CSS that allows the user to switch between images with a cross-fading effect based on CSS opacity, transition and transform properties.

How to use it:

Add as many images to the slideshow following the HTML structure as these:

<div class="carousel">
  <input type="radio" id="carousel-1" name="carousel" checked>
  <input type="radio" id="carousel-2" name="carousel">
  <input type="radio" id="carousel-3" name="carousel">
  <input type="radio" id="carousel-4" name="carousel">
  <input type="radio" id="carousel-5" name="carousel">
  <ul class="carousel__items">
      <li class="carousel__item"><img src="1.jpg" alt=""></li>
      <li class="carousel__item"><img src="2.jpg" alt=""></li>
      <li class="carousel__item"><img src="3.jpg" alt=""></li>
      <li class="carousel__item"><img src="4.jpg" alt=""></li>
      <li class="carousel__item"><img src="5.jpg" alt=""></li>
  </ul>
  <div class="carousel__prev">
      <label for="carousel-1"></label>
      <label for="carousel-2"></label>
      <label for="carousel-3"></label>
      <label for="carousel-4"></label>
      <label for="carousel-5"></label>
  </div>
  <div class="carousel__next">
      <label for="carousel-1"></label>
      <label for="carousel-2"></label>
      <label for="carousel-3"></label>
      <label for="carousel-4"></label>
      <label for="carousel-5"></label>
  </div>
  <div class="carousel__nav">
      <label for="carousel-1"></label>
      <label for="carousel-2"></label>
      <label for="carousel-3"></label>
      <label for="carousel-4"></label>
      <label for="carousel-5"></label>
  </div>
</div>

The required CSS styles for the slideshow. Just copy and insert the CSS snippets into your document and the carousel works.
