尝试添加class="text-center"到div col元素：

<div class="col-xs-12 text-center" id="buttonList">

尝试使用样式“margin：0 auto;”

You can try:

margin-left:auto; margin-right:auto margin-left:auto; margin-right:auto for horizontal alignment;

margin-top:auto; margin-bottom:auto margin-top:auto; margin-bottom:auto , for vertical alignment

margin:auto for both.
