网页设计轮播图片每隔五秒换图片且对应的标题也更换，所有图片上层有一个所有图片的标题列表，图片更换时，列表里面的标题也随之变化且对应图片，要求html和css和js写在一起，不用分文件

要创建一个网页设计中的图片轮播效果，结合HTML、CSS和JavaScript，可以按照以下步骤操作：

1. HTML结构:

<div class="carousel-container">
  <div class="slide">
    <img src="image1.jpg" alt="Slide 1">
    <h2 class="slide-title">Title 1</h2>
  </div>
  <!-- Add more slide elements with appropriate images and titles -->
  ...
  <ol class="caption-list">
    <li>Image 1</li>
    <!-- Repeat for all slide titles -->
  </ol>
</div>

2. CSS样式:

.carousel-container {
  position: relative;
  width: 100%;
}

.slide {
  position: absolute;
  opacity: 0;
  transition: opacity 0.5s ease;
}

.slide.active {
  opacity: 1;
}

.caption-list {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  list-style-type: none;
  text-align: center;
}

3. JavaScript (using vanilla JS):

const slides = document.querySelectorAll('.slide');
const captionList = document.querySelector('.caption-list');

let currentIndex = 0;

function changeSlide(newIndex) {
  slides.forEach((slide, index) => {
    if (index === newIndex) {
      slide.classList.add('active');
    } else {
      slide.classList.remove('active');
    }
  });

  captionList.innerHTML = captions[newIndex];
}

setInterval(() => {
  const totalSlides = slides.length;
  currentIndex = (currentIndex + 1) % totalSlides; // Loop the index
  changeSlide(currentIndex);
}, 5000); // Change image every 5 seconds

// Initialize with the first slide
changeSlide(0);

这段代码会设置一个图片轮播，图片每隔5秒自动切换，同时更新标题。请注意，你需要替换`image1.jpg`和相应的标题为实际图片路径和标题。
