效果如下:
css:
body { font-family:\"Microsoft Yahei\"; }
body,ul,li,img,h3,dl,dd,dt,h1{margin:0px;padding:0px;list-style:none;}
img{vertical-align: top;}
/***大图切换***/
.scroll_view{margin: 0px auto;overflow:hidden;position: relative;}
.photo_view li{position:absolute;width: 100%;}
.photo_view li em,.photo_view li h3{position: absolute;bottom: 0px;z-index: 1;height: 35px;line-height: 35px;width: 100%;left: 0px;}
.photo_view li em{z-index: 1;background:rgba(0,0,0,0.5);filter: progid:DXImageTransform.Microsoft.gradient( GradientType = 0,startColorstr = \'#50000000\',endColorstr = \'#50000000\');_background:#000;}
.photo_view li h3{z-index: 2;text-indent: 1em;font-weight: normal;}
.photo_view li h3 a{color:#fff;}
.photo_view li h3 a:hover{color:#f60;}
.small_photo{position: absolute;bottom: 40px;right: 10px;cursor: pointer;z-index: 4;}
.small_photo li {float: left;padding-right: 10px;}
.small_photo li img{width: 80px;height: 35px;border: solid 2px #ccc;border-radius: 2px;}
.small_photo li.active img{border: solid 2px #f60;}
