一共提供5中樣式，有閃光，有邊框變幻。
只能說樣式確實很酷，還是親自試試效果吧。
查看效果
使用方法：
先引用css文件htbtn.css：
<link rel="stylesheet" type="text/css" href="http://hovertree.com/texiao/css3/28/css/htbtn.css">
然後外層加類htcontainer，按鈕加類htbtn，再加類htbtn-1或者htbtn-2等，一共5種，
如果是htbtn-1的話，多加一個svg元素
html代碼：
<div class="htcontainer">
<a href="http://hovertree.com/" class="htbtn htbtn-1">
<svg>
<rect x="0" y="0" fill="none" width="100%" height="100%" />
</svg>
光標懸浮
</a>
<a href="http://hovertree.com/h/bjaf/4slmqpp2.htm" class="htbtn htbtn-2">何問起</a>
</div>
