CSS实现广告自动轮播

以下是一个简单的CSS实现广告自动轮播的例子：




<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Auto-Playing Ads</title>
<style>
  .ads {
    display: flex;
    overflow: hidden;
    width: 300px;
    height: 200px;
  }
 
  .ads-container {
    display: flex;
    transition: transform 0.5s ease;
  }
 
  .ads-slide {
    flex: 1 0 auto;
    display: flex;
    align-items: center;
    justify-content: center;
    background-color: #f2f2f2;
    position: relative;
  }
 
  .ads-dot {
    width: 8px;
    height: 8px;
    border-radius: 50%;
    background-color: #ccc;
    margin: 0 4px;
    cursor: pointer;
    transition: background-color 0.3s ease;
  }
 
  .ads-dot.active {
    background-color: #000;
  }
</style>
</head>
<body>
 
<div class="ads">
  <div class="ads-container">
    <div class="ads-slide"><img src="ad1.jpg" alt="Ad 1"></div>
    <div class="ads-slide"><img src="ad2.jpg" alt="Ad 2"></div>
    <div class="ads-slide"><img src="ad3.jpg" alt="Ad 3"></div>
  </div>
</div>
 
<script>
  const adsContainer = document.querySelector('.ads-container');
  const adsDots = document.querySelectorAll('.ads-dot');
  let currentIndex = 0;
 
  function showSlide(index) {
    const translateX = `-${index * 100}%`;
    adsContainer.style.transform = `translateX(${translateX})`;
  }
 
  function updateDots(index) {
    adsDots.forEach((dot, dotIndex) => {
      dot.classList.toggle('active', dotIndex === index);
    });
  }
 
  function autoPlay() {
    currentIndex = (currentIndex + 1) % adsDots.length;
    showSlide(currentIndex);
    updateDots(currentIndex);
  }
 
  setInterval(autoPlay, 3000);
</script>
 
</body>
</html>

这段代码包含了一个简单的自动轮播广告的实现。它使用了CSS Flexbox来布局广告容器和广告元素，并使用JavaScript来控制自动播放。setInterval函数用于每隔3秒自动切换到下一个广告。这个例子假设你有三张广告图片（ad1.jpg, ad2.jpg, ad3.jpg）供轮播展示。
