如何想取消hover的效果，可以将button标签换成span便签

<span class="btn btn-default btn-circle-micro white"></span>
<span class="btn btn-default btn-circle-micro red"></span>
<span class="btn btn-default btn-circle-micro blue"></span>
<span class="btn btn-default btn-circle-micro green"></span>
<span class="btn btn-default btn-circle-micro yellow"></span>
<span class="btn btn-default btn-circle-micro brown"></span>
<span class="btn btn-default btn-circle-micro purple"></span>
