具体效果看本站首页侧边栏，实现起来其实也挺容易的。

1、css

aside.sidebar nav{height:250px;overflow:hidden}aside nav ul{list-style-type:none;text-align:center}aside nav 
ul li{float:left;width:115px;line-height:124px;height:124px;margin-right:2px}aside nav ul li.ab
{background:#71a532}aside nav ul li.ab a:hover{-moz-transform:rotate(360deg);-webkit-transform:rotate
(360deg);-o-transform:rotate(360deg);background:#666;-webkit-transition:all 1s}aside nav ul li.sy
{background:#f90}aside nav ul li.sy a:hover{-moz-transform:rotate(360deg);-webkit-transform:rotate(360deg);-
o-transform:rotate(360deg);background:#F60;-webkit-transition:all 1s}aside nav ul li.js{background:#8c49ad}
aside nav ul li.js a:hover{-moz-transform:rotate(360deg);-webkit-transform:rotate(360deg);-o-transform:rotate
(360deg);background:#66C;-webkit-transition:all 1s}aside nav ul li.msh{background:#e7769e}aside nav ul li.msh 
a:hover{-moz-transform:rotate(360deg);-webkit-transform:rotate(360deg);-o-transform:rotate
(360deg);background:#F66;-webkit-transition:all 1s}aside nav ul li.xc{background:#a98659}aside nav ul li.xc 
a:hover{-moz-transform:rotate(360deg);-webkit-transform:rotate(360deg);-o-transform:rotate
(360deg);background:#C93;-webkit-transition:all 1s}aside nav ul li.ly{background:#63a8e8}aside nav ul li.ly 
a:hover{-moz-transform:rotate(360deg);-webkit-transform:rotate(360deg);-o-transform:rotate
(360deg);background:#06C;-webkit-transition:all 1s}aside nav ul li a{display:block;color:#FFF}aside nav ul li 
a:hover{font-weight:bold;color:#FF0}

2、Html

在小工具栏新建文本，拷贝下面的代码：

<nav>
      <ul>
        <li class="ab"><a href="#" rel="no follow" target="_blank">建站软件</a></li>
        <li class="sy"><a href="#" rel="no follow" target="_blank">知更鸟专题</a></li>
        <li class="js"><a href="#" rel="no follow" target="_blank">Xiu专题</a></li>
        <li class="msh"><a href="#" rel="no follow"  target="_blank">Yusi专题</a></li>
        <li class="xc"><a href="#"  rel="no follow" target="_blank">淘宝客</a></li>
        <li class="ly"><a href="#" rel="no follow" target="_blank">诗集</a></li>
     </ul>      
    </nav>
