越来越喜欢CSS3的Transition属性
HTML:

复制代码代码如下:
<div class="nav">
<li><a href="#">HOME</a></li>
<li><a href="#">LIFE</a></li>
<li><a href="#">WEB</a></li>
<li><a href="#">PHP</a></li>
<li><a href="#">PIC</a></li>
<li><a href="#">ABOUT</a></li>
</div>

CSS:

复制代码代码如下:
<style>
body{
background:#EDEDED;
}</p><p>.nav{
width:606px;
margin:100px auto 0 auto;
}</p><p>li{
