h5轮播图

H5轮播图可以使用HTML、CSS和JavaScript来实现，以下是一个简单的示例：

HTML代码：

<div class="slideshow-container">
  <div class="mySlides fade">
    <img src="img1.jpg" style="width:100%">
  </div>
  <div class="mySlides fade">
    <img src="img2.jpg" style="width:100%">
  </div>
  <div class="mySlides fade">
    <img src="img3.jpg" style="width:100%">
  </div>
</div>

CSS代码：

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

.mySlides {
  display: none;
}

.prev, .next {
  cursor: pointer;
  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;
}

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

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

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

@-webkit-keyframes fade {
  from {
    opacity: .4
  }
  to {
    opacity: 1
  }
}

@keyframes fade {
  from {
    opacity: .4
  }
  to {
    opacity: 1
  }
}

JavaScript代码：

var slideIndex = 0;
showSlides();

function showSlides() {
  var i;
  var slides = document.getElementsByClassName("mySlides");
  for (i = 0; i < slides.length; i++) {
    slides[i].style.display = "none";
  }
  slideIndex++;
  if (slideIndex > slides.length) {slideIndex = 1}
  slides[slideIndex-1].style.display = "block";
  setTimeout(showSlides, 4000); // 切换时间间隔为4秒
}

这是一个基本的轮播图，你可以根据自己的需求进行修改和扩展。
