</ul> 

css代碼：

復制代碼代碼如下:

 
*{ margin:0; padding:0;} 
.list{ width:640px; margin:100px auto; border:1px solid #ddd; overflow:hidden;} 
.list li{ float:left; width:150px; height:80px; overflow:hidden; list-style:none; margin:5px; display:inline; position:relative;} 
.list li img{ float:left; width:150px; height:80px; border:none;} 
.list li a{ position:absolute; left:0; top:0; width:150px; height:0; background:#999; margin-top:40px; display:inline; text-align:center; line-height:80px; overflow:hidden; color:#fff; text-decoration:none;} 

jq代碼（注意要引入jq庫）：

復制代碼代碼如下:

 
$(function () { 
$('.list li').hover(function () { 
$(this).children('a,img').stop(); 
$(this).children('img').stop().animate({ 'marginTop': 40, 'height': 0 }, 200, function () { 
$(this).siblings('a').stop().animate({ 'height': 80, 'marginTop': 0 }, 200); 
}); 

}, function () { 
$(this).children('a,img').stop(); 
$(this).children('a').stop().animate({ 'height': 0, 'marginTop': 40 }, 200, function () { 
$(this).siblings('img').stop().animate({ 'marginTop': 0, 'height': 80 }, 200); 

}); 
}); 

}); 

是不是很簡單的幾句jq代碼？親，不妨copy下來看下效果唄！
