通过上图大家会发现:如果在单个行中放置超过12列，则每组额外列将作为一个单位包装到新行上。

        <div class="row">

            <div class="col-xs-12 col-md-8">.col-xs-12 col-md-8</div>

            <div class="col-xs-6 col-md-4">.col-xs-6 col-md-4</div>

        </div>

在这段代码中大家看图当页面缩小到815px时,网格是以 .col-xs-12和.col-xs-6分割的,又因为 .col-xs-12 已经等于12列了,所以后面的那个 <div class="col-xs-6 col-md-4">.col-xs-6 col-md-4</div> 额外列将作为一个单位包装到新行上。示例如下:

        <div class="row">

            <div class="col-xs-1 col-md-1">.col-xs-1 .col-md-1</div>

            <div class="col-xs-1 col-md-1">.col-xs-1 .col-md-1</div>

            <div class="col-xs-1 col-md-1">.col-xs-1 .col-md-1</div>

            <div class="col-xs-1 col-md-1">.col-xs-1 .col-md-1</div>

            <div class="col-xs-1 col-md-1">.col-xs-1 .col-md-1</div>

            <div class="col-xs-1 col-md-1">.col-xs-1 .col-md-1</div>

            <div class="col-xs-1 col-md-1">.col-xs-1 .col-md-1</div>

        </div>

        <!-- 如果在单个行中放置超过12列，则每组额外列将作为一个单位包装到新行上。 -->

        <div class="row">

            <div class="col-xs-9">.col-xs-9</div>

            <div class="col-xs-4">

                .col-xs-4

                <br>Since 9 + 4 = 13 &gt; 12, 这个4列宽的div被包装到一个新行上作为一个连续的单元.</div>

            <div class="col-xs-6">

                .col-xs-6

                <br>后续列将沿着新行继续。</div>

        </div>

页面中第三行的空白是因为: .col-md-offset-4 ,第四行的空白是因为: .col-md-offset-3 ,第五行的第一个空白是因为 .col-md-offset-3,第二个空白是因为哪一行只有 <div class="col-md-6 col-md-offset-3">.col-md-6 .col-md-offset-3</div>,后面没有内容了,所以是空白的.

第二行的空白是因为页面缩小后,它按照: <div class="col-md-5">.col-sm-6 .col-md-5 .col-lg-6</div>和<div class="col-md-5 col-md-offset-2"> .col-sm-6 .col-md-5 .col-md-offset-2 .col-lg-6 .col-lg-offset-0 </div>去进行网格分割的,因为col-md-offset-2所以中间会两个网格的空白.
