为我编写一个html+css的高级轮播图

以下是一个简单的 HTML + CSS 高级轮播图示例：

HTML 代码：

<div class="slider-container">
  <div class="slider">
    <div class="slide slide1"></div>
    <div class="slide slide2"></div>
    <div class="slide slide3"></div>
  </div>
  <div class="slider-nav">
    <div class="nav-item nav1"></div>
    <div class="nav-item nav2"></div>
    <div class="nav-item nav3"></div>
  </div>
</div>

CSS 代码：

.slider-container {
  position: relative;
  width: 600px;
  height: 400px;
  overflow: hidden;
}

.slider {
  position: absolute;
  top: 0;
  left: 0;
  width: 300%;
  height: 100%;
  display: flex;
  transition: all 0.5s ease;
}

.slide {
  width: 33.333%;
  height: 100%;
  background-size: cover;
  background-position: center;
}

.slide1 {
  background-image: url('slide1.jpg');
}

.slide2 {
  background-image: url('slide2.jpg');
}

.slide3 {
  background-image: url('slide3.jpg');
}

.slider-nav {
  position: absolute;
  bottom: 20px;
  left: 50%;
  transform: translateX(-50%);
  display: flex;
}

.nav-item {
  width: 10px;
  height: 10px;
  border-radius: 50%;
  margin-right: 10px;
  background-color: #ccc;
  cursor: pointer;
  transition: all 0.5s ease;
}

.nav-item.active {
  background-color: #fff;
}

JavaScript 代码：

var slider = document.querySelector('.slider');
var slides = document.querySelectorAll('.slide');
var navItems = document.querySelectorAll('.nav-item');

var currentSlide = 0;
var slideInterval = setInterval(nextSlide, 5000);

function nextSlide() {
  slider.style.transform = 'translateX(-' + (currentSlide + 1) * 33.333 + '%)';
  navItems[currentSlide].classList.remove('active');
  currentSlide++;
  if (currentSlide >= slides.length) {
    currentSlide = 0;
  }
  navItems[currentSlide].classList.add('active');
}

for (var i = 0; i < navItems.length; i++) {
  navItems[i].addEventListener('click', function() {
    clearInterval(slideInterval);
    slider.style.transform = 'translateX(-' + (this.dataset.index * 33.333) + '%)';
    navItems[currentSlide].classList.remove('active');
    currentSlide = this.dataset.index;
    navItems[currentSlide].classList.add('active');
    slideInterval = setInterval(nextSlide, 5000);
  });
}

注意：以上代码仅为示例，实际应用中可能需要根据具体需求进行修改和优化。
