对应的图片地址改为自己的图片地址：

HTML 代码：

<div class="slideshow-container"><div class="mySlides fade"><div class="numbertext">1 / 3</div><img src="img1.jpg" style="width:100%"><div class="text">文本 1</div></div><div class="mySlides fade"><div class="numbertext">2 / 3</div><img src="img2.jpg" style="width:100%"><div class="text">文本 2</div></div><div class="mySlides fade"><div class="numbertext">3 / 3</div><img src="img3.jpg" style="width:100%"><div class="text">文本 3</div></div><a class="prev" onclick="plusSlides(-1)">❮</a><a class="next" onclick="plusSlides(1)">❯</a></div><br><div style="text-align:center"><span class="dot" onclick="currentSlide(1)"></span><span class="dot" onclick="currentSlide(2)"></span><span class="dot" onclick="currentSlide(3)"></span></div>

CSS 代码设置上一张下一张图片的按钮及文本。

CSS 代码：

* {box-sizing:border-box}body {font-family: Verdana,sans-serif;}.mySlides {display:none}/* 幻灯片容器 */.slideshow-container {max-width: 1000px;position: relative;margin: auto;}/* 下一张 & 上一张 按钮 */.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;}/* 定位 "下一张" 按钮靠右 */.next {right: 0;border-radius: 3px 0 0 3px;}/* On hover, add a black background color with a little bit see-through */.prev:hover, .next:hover {background-color: rgba(0,0,0,0.8);}/* 标题文本 */.text {color: #f2f2f2;font-size: 15px;padding: 8px 12px;position: absolute;bottom: 8px;width: 100%;text-align: center;}/* 数字文本 (1/3 等) */.numbertext {color: #f2f2f2;font-size: 12px;padding: 8px 12px;position: absolute;top: 0;}/* 标记符号 */.dot {cursor:pointer;height: 13px;width: 13px;margin: 0 2px;background-color: #bbb;border-radius: 50%;display: inline-block;transition: background-color 0.6s ease;}.active, .dot:hover {background-color: #717171;}/* 淡出动画 */.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 = 1;showSlides(slideIndex);function plusSlides(n) {showSlides(slideIndex += n);}function currentSlide(n) {showSlides(slideIndex = n);}function showSlides(n) {var i;var slides = document.getElementsByClassName("mySlides");var dots = document.getElementsByClassName("dot");if (n > slides.length) {slideIndex = 1}if (n < 1) {slideIndex = slides.length}for (i = 0; i < slides.length; i++) {slides[i].style.display = "none";}for (i = 0; i < dots.length; i++) {dots[i].className = dots[i].className.replace(" active", "");}slides[slideIndex-1].style.display = "block";dots[slideIndex-1].className += " active";}

你也可以将幻灯片设置为自动播放 JavaScript 代码修改为如下：

JavaScript 代码：

var slideIndex = 0;showSlides();function showSlides() {var i;var slides = document.getElementsByClassName("mySlides");var dots = document.getElementsByClassName("dot");for (i = 0; i < slides.length; i++) {slides[i].style.display = "none";}slideIndex++;if (slideIndex > slides.length) {slideIndex = 1}for (i = 0; i < dots.length; i++) {dots[i].className = dots[i].className.replace(" active", "");}slides[slideIndex-1].style.display = "block";dots[slideIndex-1].className += " active";setTimeout(showSlides, 2000); // 切换时间为 2 秒}
