<!DOCTYPE html>

<br> var slideIndex = 1;<br> showSlides(slideIndex);</p> <p>function plusSlides(n) {<br> showSlides(slideIndex += n);<br> }</p> <p>function currentSlide(n) {<br> showSlides(slideIndex = n);<br> }</p> <p>function showSlides(n) {<br> var i;<br> var slides = document.getElementsByClassName("mySlides");<br> var dots = document.getElementsByClassName("dot");<br> if (n > slides.length) {slideIndex = 1} <br> if (n < 1) {slideIndex = slides.length}<br> for (i = 0; i < slides.length; i++) {<br> slides[i].style.display = "none"; <br> }<br> for (i = 0; i < dots.length; i++) {<br> dots[i].className = dots[i].className.replace(" active", "");<br> }<br> slides[slideIndex-1].style.display = "block"; <br> dots[slideIndex-1].className += " active";<br> }<br> * {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} } .zong{ width:100%; height: 500px; position: absolute; bottom: 0%; border:2px solid red; }
