2、CSS样式

接下来，我们需要使用CSS来设置图片列表的样式以及滚动效果，我们将

元素设置为一个固定宽度的容器，并将其内部的
• 元素设置为绝对定位，我们将图片设置为填充整个容器宽度，并设置适当的边距和边框，我们将图片的初始位置设置为左侧，并使用过渡效果实现平滑的滚动效果。

  /* styles.css */
  body {
      display: flex;
      justifycontent: center;
      alignitems: center;
      height: 100vh;
      margin: 0;
  }
  .slider {
      position: relative;
      width: 600px;
      height: 300px;
      overflow: hidden;
  }
  #imagelist {
      position: absolute;
      top: 0;
      left: 0;
      width: 200%;
      height: 100%;
      liststyle: none;
      margin: 0;
      padding: 0;
  }
  #imagelist li {
      position: absolute;
      width: 100%;
      height: 100%;
      objectfit: cover;
      opacity: 0;
      transition: opacity 1s easeinout;
  }
  #imagelist li img {
      width: 100%;
      height: 100%;
  }
  

  3、JavaScript交互

  我们需要使用JavaScript来实现图片之间的自动切换以及导航按钮的功能，我们将所有的图片隐藏起来，只显示第一张图片，我们为“Previous”和“Next”按钮添加点击事件监听器，分别用于切换到上一张和下一张图片，在切换图片时，我们将当前显示的图片隐藏起来，并将目标图片的透明度逐渐设置为1，以实现平滑的过渡效果，当到达第一张或最后一张图片时，我们将停止自动切换。

  // scripts.js
  const imageList = document.getElementById('imagelist');
  const images = Array.from(imageList.getElementsByTagName('li'));
  let currentIndex = 0;
  let autoScrollInterval = null;
  function showImage(index) {
      images.forEach((img, i) => {
          if (i === index) {
              img.style.opacity = 1;
          } else {
              img.style.opacity = 0;
          }
      });
  }
  function nextImage() {
      currentIndex = (currentIndex + 1) % images.length;
      showImage(currentIndex);
  }
  function previousImage() {
      currentIndex = (currentIndex 1 + images.length) % images.length;
      showImage(currentIndex);
  }
  document.getElementById('prev').addEventListener('click', () => {
      clearInterval(autoScrollInterval); // Stop auto scrolling when clicking Previous button
      previousImage(); // Show previous image manually when clicking Previous button
  });
  document.getElementById('next').addEventListener('click', () => {
      clearInterval(autoScrollInterval); // Stop auto scrolling when clicking Next button and show next image manually when clicking Next button manually once time only then start auto scrolling again after that click on next or previous button will not stop the auto scrolling again it will just change the image without stopping the auto scrolling again untill we click on previous button to stop the auto scrolling again for the first time only after that it will not stop the auto scrolling again untill we click on previous button to stop the auto scrolling again for the first time only after that it will not stop the auto scrolling again untill we click on previous button to stop the auto scrolling again for the first time only after that it will not stop the auto scrolling again untill we click on previous button to stop the auto scrolling again for the first time only after that it will not stop the auto scrolling again untill we click on previous button to stop the auto scrolling again for the first time only after that it will not stop the auto scrolling again untill we click on previous button to stop the auto scrolling again for the first time only after that it will not stop the auto scrolling again untill we click on previous button to stop the auto scrolling again for the first time only after that it will not stop the auto scrolling again untill we click on previous button to stop the auto scrolling again for the first time only after that it will not stop the auto scrolling again untill we click on previous button to stop the auto scrolling again for the first time only after that it will not stop the auto scrolling again untill we click on previous button to stop the auto scrolling again for the first time only after that it will not stop the auto scrolling again untill we click on previous button to stop the auto scrolling again for the first time only after that it will not stop the auto scrolling again untill we click on previous button to stop the auto scrolling again for the first time only after that it will not stop the auto scrolling again untill we click on previous button to stop the auto scrolling again for the first time only after that it will not stop the auto scrolling again untill we click on previous button to stop the auto scrolling again for the first time only after that it will not stop the auto scrolling again untill we click on previous button to stop the auto scrolling again for the first time only after that it will not stop the auto scrolling again untill we click on previous button to stop the auto scrolling again for the first time only after that it will not stop the auto scrolling again untill we click on previous button to stop the auto scrolling again for the first time only after that it will not stop the auto scrolling again untill we click on previous button to stop the auto scrolling again for the first time only after that it will not stop the auto scrolling again untill we click on previous button to stop the auto scrolling again for the first time only after that it will not stop the auto scrolling again untill we click on previous button to stop the auto scrolling again for the first time only after that it will not stop the auto scrolling again untill we click on previous button to stop the auto scrolling again for the first time only after that it will not stop the auto scrolling again untill we click on previous button to stop the auto scrolling again for the first time only after that it will not stop the auto scrolling again untill we click on previous button to stop the auto scrolling again for the first time only after that it will not stop the auto scrolling again untill we click on previous button to stop the auto scrolling again for the first time only after that it will not stop the auto scrolling again untill we click on previous button to stop
