CSS实现的一个图片放大展示的一种思路

这个用纯css实现的图片放大效果,真不错,看了以前有不少用纯css实现的图片放大效果的代码,都不理想,还是在这个好啊
看下面的HTML代码：
<div class="photo">
<ul>
<li><a href="#nogo1" class="hor"><img src=http://www.jb51.net/logo.gif  alt="" title="" /><b>Snow capped mountains</b></a></li> </ul>
</div>
下面是CSS代码：


代码如下:

/* common styling */ 
a {color:#000;} 
a:hover {text-decoration:none;} 
a:visited {color:#000;} 
/* slides styling */ 
.photo {padding:20px; background:#222; width:600px; height:330px; text-align:left;} 
.photo h1 {font-size:14px; font-weight:normal; color:#fc0; margin:0 0 0 5px; padding:0;} 
.photo ul {list-style:none; padding:0; margin:0; width:216px; background:#333; border:1px solid #666; position:relative; height:144px;} 
.photo ul li {display:inline; width:24px; height:24px; float:left; margin:6px;} 
.photo ul li a {display:block; width:24px; height:24px; cursor:default; background:url(pics/arrow.gif) no-repeat;} 
.photo ul li a b {display:none;} 
.photo ul li a img {display:block; width:22px; height:22px; border:1px solid #666; border-top-color:#ccc;}

.photo ul li a:hover {white-space:normal;position:relative;}

.photo ul li a.vert:hover img {position:absolute; left:-12px; top:-20px; width:48px; height:64px; border-color:#fc0;} 
.photo ul li a.hor:hover img {position:absolute; left:-20px; top:-12px; width:64px; height:48px; border-color:#fc0;}

.photo ul li a:active, .photo ul li a:focus {position:static; outline:0;}

.photo ul li a:focus.vert img, .photo ul li a:active.vert img {background-color:#000; position:absolute; left:260px; top:0; width:240px; height:320px; border:1px solid #fc0; padding:5px 45px;} 
.photo ul li a:focus.hor img, .photo ul li a:active.hor img {background-color:#000; position:absolute; left:260px; top:0; width:320px; height:240px; border:1px solid #fc0; padding:45px 5px;} 
.photo ul li a:focus b, .photo ul li a:active b {display:block; position:absolute; width:204px; height:150px; border:1px solid #666; top:165px; left:0; color:#ddd; font-weight:normal; padding:6px;}
