<body>
<div id="playimages" class="play">
<ul class="big_pic">
<div class="prev"></div>
<div class="next"></div>

<div class="text">加载图片说明……</div>
<div class="length">计算图片数量……</div>

<a class="mark_left" href="javascript:;"></a>
<a class="mark_right" href="javascript:;"></a>
<div class="bg"></div>

<li style="z-index:1;"><img src="images/1.jpg" /></li>
<li><img src="images/2.jpg" /></li>
<li><img src="images/3.jpg" /></li>
<li><img src="images/4.jpg" /></li>
<li><img src="images/5.jpg" /></li>
<li><img src="images/6.jpg" /></li>
</ul>
<div class="small_pic">
<ul style="width:390px;">
<li style="filter: 100; opacity: 1;"><img src="images/1.jpg" /></li>
<li><img src="images/2.jpg" /></li>
<li><img src="images/3.jpg" /></li>
<li><img src="images/4.jpg" /></li>
<li><img src="images/5.jpg" /></li>
<li><img src="images/6.jpg" /></li>
</ul>
</div>
</div>

</body>
</html>

 

注意要点:

1css页面布局,将li叠放,position:absolute;left都是0.

2.图片之所以会有高度变化,是因为,li的高度是从0-390,li里面嵌套img,img的高度是固定不变的,这样的话,高度是变化的。
