最近在帮别人改一些东西,在网上找了好久,但是没有相同的,自己改了下,拿出来分享下:
先展示下效果把:
index.html 页面展示代码

接下来是对应的JS文件内容:

OK,最后加上一些样式上的东西,就可以跑起来了;
body { margin: 0px; padding: 0px; } div { margin: 0px; padding: 0px; } ul { margin: 0px; padding: 0px; } li { margin: 0px; padding: 0px; } h4 { margin: 0px; padding: 0px; } p { margin: 0px; padding: 0px; } body { no-repeat 50% 0px rgb(0, 0, 0); font: 12px/1.8 arial; color: rgb(255, 255, 255); font-size-adjust: none; font-stretch: normal; } a { background: rgb(102, 102, 102); padding: 2px 5px; color: rgb(255, 255, 255); text-decoration: none; } a:hover { background: rgb(255, 153, 0); } #box { margin: 1px auto 0px; width: 680px; height: 320px; position: relative; } #box ul { width: 680px; height: 320px; position: relative; } #box li { background: rgb(0, 0, 0); list-style: none; border-radius: 3px; border:0px solid rgb(0, 0, 0); left: 377px; top: 146px; width: 0px; height: 0px; overflow: hidden; position: absolute; z-index: 0; cursor: pointer; } #box li div { background: rgb(0, 0, 0); width: 100%; height:40px; bottom: -100px; position: absolute; opacity: 0.7; } #box li div h4 { font: 12px/24px arial; margin: 0px 10px; border-bottom-color: rgb(51, 51, 51); border-bottom-width: 1px; border-bottom-style: solid; font-size-adjust: none; font-stretch: normal; } #box li div h4 span { color: red; margin-left: 10px; } #box li div p { margin: 5px 10px 0px; text-indent: 2em; } .numbutLeft{width: 15px; height: 5px; background-color:#AFB7B6; float: left; cursor: pointer;} .numbut{width: 15px; height: 5px; background-color:#AFB7B6; float: left; margin-left: 5px; cursor: pointer;} .numbutCen{width: 15px; height: 5px; background-color:#FF0000; float: left; margin-left: 5px; cursor: pointer;} .numbutLeftCen{width: 15px; height: 5px; background-color:#FF0000; float: left; cursor: pointer;} .numbutdiv{height: 10px;width: 100%;color: red;margin-top: 0px; padding-top: 0px} .ndv{height: 10px;width: 95px; margin: 0 auto} #box .next { background-position: -39px 0px; right: -60px; } #copyright { text-align: center; padding-top: 10px; }
OOOOOKKK 了,奇特的效果就要出来了 ,还有一些不完美的地方,懒得去改了,有高手可以改改看,但希望分享哦。
效果如下:
