Creating a carousel using CSS can be achieved using CSS animations and transforms. Here is an example of how to create a basic carousel using CSS: HTML: 
 <div class="carousel-container">
  <div class="carousel">
    <div class="slide">
      <img src="" alt="Image 1">
    </div>
    <div class="slide">
      <img src="" alt="Image 2">
    </div>
    <div class="slide">
      <img src="image3.jpg" alt="Image 3">
    </div>
  </div>
</div>
</div>
CSS: 

.carousel-container {
  width: 100%;
  overflow: hidden;
}

.carousel {
  display: flex;
  width: 300%;
  animation: slide 10s infinite;
}

.slide {
  width: 33.33%;
  padding: 10px;
  box-sizing: border-box;
}

.slide img {
  width: 100%;
}

@keyframes slide {
  0% {
    transform: translateX(0);
  }
  33.33% {
    transform: translateX(-100%);
  }
  66.66% {
    transform: translateX(-200%);
  }
  100% {
    transform: translateX(0);
  }
}
In this example, we have a container with the class "carousel-container" that has an overflow of hidden to hide the overflow of the carousel. The carousel itself has a width of 300% to accommodate the width of all the slides, and a flex display to align the slides horizontally. The slides have a width of 33.33% to ensure that all three slides fit within the carousel container. The slide images have a width of 100% to fill the width of their respective slides. The @keyframes rule defines the animation for the carousel, where we translate the carousel horizontally by 100% for each slide, and then back to 0% to create the carousel effect. The animation is set to repeat infinitely with a duration of 10 seconds. Note that this is a basic example, and you can modify the styles and animation to fit your specific needs and design.
