如果您需要lg上的3个项目和xs上的2个项目，则必须使用列包装和响应式重置。 col-的所有应该在一个.row中...
<div class="row">
<div class="col-lg-4 col-xs-6"> 1 </div>
<div class="col-lg-4 col-xs-6"> 2 </div>
<!-- clearfix xs cols every 2 -->
<div class="clearfix visible-xs"></div>
<div class="col-lg-4 col-xs-6"> 3 </div>
<!-- clearfix lg cols every 3 -->
<div class="clearfix visible-lg"></div>
<div class="col-lg-4 col-xs-6"> 4 </div>
<div class="clearfix visible-xs"></div>
<div class="col-lg-4 col-xs-6"> 5 </div>
<div class="col-lg-4 col-xs-6"> 6 </div>
<div class="clearfix visible-xs visible-lg"></div>
<div class="col-lg-4 col-xs-6"> 7 </div>
<div class="col-lg-4 col-xs-6"> 8 </div>
<div class="clearfix visible-xs"></div>
<div class="col-lg-4 col-xs-6"> 9 </div>
...
