不使用JS实现html中五张图片轮播

可以使用 HTML 和 CSS 实现图片轮播，以下是一个简单的例子：

<div class="slideshow-container">
  <div class="mySlides fade">
    <img src="image1.jpg" style="width:100%">
  </div>

  <div class="mySlides fade">
    <img src="image2.jpg" style="width:100%">
  </div>

  <div class="mySlides fade">
    <img src="image3.jpg" style="width:100%">
  </div>

  <div class="mySlides fade">
    <img src="image4.jpg" style="width:100%">
  </div>

  <div class="mySlides fade">
    <img src="image5.jpg" style="width:100%">
  </div>

  <a class="prev" onclick="plusSlides(-1)">&#10094;</a>
  <a class="next" onclick="plusSlides(1)">&#10095;</a>
</div>

<br>

<div style="text-align:center">
  <span class="dot" onclick="currentSlide(1)"></span>
  <span class="dot" onclick="currentSlide(2)"></span>
  <span class="dot" onclick="currentSlide(3)"></span>
  <span class="dot" onclick="currentSlide(4)"></span>
  <span class="dot" onclick="currentSlide(5)"></span>
</div>

CSS 样式：

* {
  box-sizing: border-box;
}

.slideshow-container {
  max-width: 1000px;
  position: relative;
  margin: auto;
}

.mySlides {
  display: none;
}

.prev,
.next {
  position: absolute;
  top: 50%;
  width: auto;
  margin-top: -22px;
  padding: 16px;
  color: white;
  font-weight: bold;
  font-size: 18px;
  transition: 0.6s ease;
  border-radius: 0 3px 3px 0;
  user-select: none;
}

.next {
  right: 0;
  border-radius: 3px 0 0 3px;
}

.prev:hover,
.next:hover {
  background-color: rgba(0, 0, 0, 0.8);
}

.dot-container {
  text-align: center;
  padding: 20px;
  background: #ddd;
}

.dot {
  cursor: pointer;
  height: 15px;
  width: 15px;
  margin: 0 2px;
  background-color: #bbb;
  border-radius: 50%;
  display: inline-block;
  transition: background-color 0.6s ease;
}

.active,
.dot:hover {
  background-color: #717171;
}

.fade {
  -webkit-animation-name: fade;
  -webkit-animation-duration: 1.5s;
  animation-name: fade;
  animation-duration: 1.5s;
}

@-webkit-keyframes fade {
  from {
    opacity: 0.4;
  }

  to {
    opacity: 1;
  }
}

@keyframes fade {
  from {
    opacity: 0.4;
  }

  to {
    opacity: 1;
  }
}

JavaScript：

var slideIndex = 1;
showSlides(slideIndex);

function plusSlides(n) {
  showSlides((slideIndex += n));
}

function currentSlide(n) {
  showSlides((slideIndex = n));
}

function showSlides(n) {
  var i;
  var slides = document.getElementsByClassName("mySlides");
  var dots = document.getElementsByClassName("dot");
  if (n > slides.length) {
    slideIndex = 1;
  }
  if (n < 1) {
    slideIndex = slides.length;
  }
  for (i = 0; i < slides.length; i++) {
    slides[i].style.display = "none";
  }
  for (i = 0; i < dots.length; i++) {
    dots[i].className = dots[i].className.replace(" active", "");
  }
  slides[slideIndex - 1].style.display = "block";
  dots[slideIndex - 1].className += " active";
}

这个例子中有五张图片，使用 fade 类来实现图片的淡入淡出效果，同时也包括了左右箭头和圆点来切换图片。每次调用 `showSlides` 函数时都会将当前图片隐藏，然后显示下一张或上一张图片。可以通过 `currentSlide` 函数来直接跳转到指定的图片。
