之前写了一个焦点图左右轮播的,感觉淡出淡入用得也比较多,就干脆一起放上来啦。这个容器用了百分比宽度,图片始终保持居中处理,定宽或者自适应宽度都是可以的。
兼容到IE6+以上浏览器,有淡出淡入速度和切换间隔两个参数可以改。效果图如下:
Html代码如下:
<!doctype html><html lang="zh-CN"><head> <meta charset="utf-8"> <title>淡出淡入焦点图</title> <link href="CSS/style.css" rel="stylesheet"/> <script src="js/jquery-1.9.1.min.js"></script> <script src="js/common.js"></script></head><body> <div class="wrap"> <div class="banner"> <div class="bannerCon"> <!-- 容器有做自适应宽度处理,下面的图片会保持居中显示,建议使用最大尺寸的图片填充 --> <ul class="imgList"> <li><a href="#"><img src="images/banner01.jpg" alt=""/></a></li> <li><a href="#"><img src="images/banner02.jpg" alt=""/></a></li> <li><a href="#"><img src="images/banner03.jpg" alt=""/></a></li> </ul> <ul class="btnList"> <li class="cur"><span></span></li> <li><span></span></li> <li><span></span></li> </ul> <span class="PRe-nex prev"><</span> <span class="pre-nex next">></span> </div> </div> </div></body></html>
Css样式如下:
@charset "utf-8";/* 简单reset */body, p, ul, ol, li { margin: 0; padding: 0;}ul, ol { list-style: none;}img { border:none; }a,button{ outline: none; }.clearfix:after { visibility: hidden; display: block; font-size: 0; content: " "; clear: both; height: 0;} /* 具体样式 */.banner { height: 400px; }.banner .bannerCon { position: relative; width: 60%; height: 100%; margin: 0 auto; overflow: hidden;}.bannerCon .imgList { width: 100%; height: 100%;}.bannerCon .imgList li { display: none; position: absolute; top: 0; left: 0; width: 100%; height: 100%; background-color: #e2f6fd; /* 这个背景是为了展示宽度大于图片宽度时的区域,可以删除 */ z-index: 1;}.bannerCon .imgList li a { display: block; height: 100%; text-align: center;}.imgList li a img { position: absolute; top: 0; left: 50%; margin-left: -400px; /* 这个数值填图片的实际宽度的一半 */}.bannerCon .pre-nex { display: none; position: absolute; top: 50%; width: 40px; height: 60px; margin-top: -40px; font: bold 40px/60px Simsun; color: #ccc; text-align: center; border:none; background: rgba(0,0,0,.30); filter:progid:DXImageTransform.Microsoft.Gradient(startColorStr=#4c000000, endColorStr=#4c000000); cursor: pointer; z-index: 3;}.bannerCon .pre-nex.show { display: inline-block; }.bannerCon .prev { left: 13%; }.bannerCon .next { right: 13%; }.bannerCon .btnList { position: absolute; left: 0; bottom: 20px; width: 100%; height: 12px; text-align:center; z-index: 6; _overflow: hidden;}.bannerCon .btnList li { display: inline; }.bannerCon .btnList li span { display: inline-block; width: 12px; height: 12px; margin: 0 5px; border-radius: 6px; background-color:#14829e; cursor: pointer;}.bannerCon .btnList li.cur span { background-color: #f30; }
