为什么这十二列不显示内联？

Question

我在bootply遇到的这种奇怪的行为。我想了解为什么我有十二列网格的结果。此行为与xs，sm，md，lg列类型一起运行。

或许更了解网格系统bootstrap 3 ...但我相信12列始终和列的类型。

    <div class="container-fluid">

    <div class="row">
        <div class="col-md-2 vcenter">
            <span class="label label-primary">bla</span>
        </div>
        <div class="col-md-10 vcenter">
            <p class="textPres">Ava "fefefeef
                feeeeeeeeeeeeeeeeeeeeeeeeeeeeee
                fggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggg
                gggggggggggggggggggggggggggggggggggggggggggggggg
                gggggggggggggggggggggggggggggggggggggggggggggggg
            </p>
        </div>
    </div>

</div><!-- /.container -->
