之前已经为大家介绍了好几款css3按钮，今天要为大家介绍的是一款纯css3实现的圆形旋转分享按钮。旋转的角度可以自己调整。在demo中演示了三个角度旋转。360度，60度，-360度。如图：
看下实现代码：
html代码：
<b>360 degree spin onMouseover and onMouseout</b></p>
<p id="socialicons">
<a href="http://www.w2bc.com/">
<img border="0" src="rss.png" /></a> <a href="http://www.w2bc.com/">
<img border="0" src="delicious.png" /></a> <a href="http://www.w2bc.com/">
<img border="0" src="facebook.png" /></a> <a href="http://www.w2bc.com/">
<img border="0" src="twitter.png" /></a> <a href="http://www.w2bc.com/">
<img border="0" src="yahoo.png" /></a>
</p>
<p>
<b>60 degree spin onMouseover and onMouseout</b></p>
<p id="socialicons2">
<a href="http://www.w2bc.com/">
<img border="0" src="rss.png" /></a> <a href="http://www.w2bc.com/">

</p>
<p>
<b>-360 degree spin onMouseover ONLY</b></p>
<p id="socialicons3">
