Html 想把一个营销部门放在中心，并在其周围放一个盒子-使用Bootstrap

我使用的是Bootstrap3，我试图将营销部门放在中心，并在其周围放一个盒子。我想保持营销部门的小型化和中心化

.box只是一个带有边框的简单框

这是我的密码：

<div class="container">
    <div class="col-md-offset-2">
        <div class="row box">
            <div class="marketing">
                <div class="col-lg-3">
                    <img class="img-responsive" src="http://placehold.it/100x100" alt="placeholder" class="img-rounded">
                    <h2>Lorem Ipsum</h2>
                        <p class="marketing-desc">Lorem ipsum dolor sit amet</p>
             </div>

             <div class="col-lg-3">
                 <img class="img-responsive" src="http://placehold.it/100x100" alt="placeholder" class="img-rounded">
                    <h2>Lorem Ipsum</h2>
                        <p class="marketing-desc">Lorem ipsum dolor sit amet, quidam debitis honestatis ut eam. Dicant perpetua pro an, id mei iusto ridens. Cibo salutatus has ex..</p>
            </div>

            <div class="col-lg-3">
                <img class="img-responsive" src="http://placehold.it/100x100" alt="placeholder" class="img-rounded">
                <h2>Lorem Ipsum</h2>
                    <p class="marketing-desc">Lorem ipsum dolor sit amet, quidam debitis honestatis ut eam.</p>
                  </div>
              </div>
          </div>
     </div>
</div>

它把盒子向右边延伸得太远了，我不明白为什么两边都没有

链接看起来您的列不太完整。相反，您可以在现有列中嵌套另一行12列。尝试：

<div class="container">
    <div class="row">
        <div class="col-lg-offset-2 col-lg-8">
            <div class="row box">
                <div class="marketing">
                    <div class="col-lg-4">
                        <img class="img-responsive" src="http://placehold.it/100x100" alt="placeholder" class="img-rounded">
                        <h2>Lorem Ipsum</h2>
                        <p class="marketing-desc">Lorem ipsum dolor sit amet</p>
                    </div>

                    <div class="col-lg-4">
                        <img class="img-responsive" src="http://placehold.it/100x100" alt="placeholder" class="img-rounded">
                        <h2>Lorem Ipsum</h2>
                        <p class="marketing-desc">Lorem ipsum dolor sit amet, quidam debitis honestatis ut eam. Dicant perpetua pro an, id mei iusto ridens. Cibo salutatus has ex..</p>
                    </div>

                    <div class="col-lg-4">
                        <img class="img-responsive" src="http://placehold.it/100x100" alt="placeholder" class="img-rounded">
                        <h2>Lorem Ipsum</h2>
                        <p class="marketing-desc">Lorem ipsum dolor sit amet, quidam debitis honestatis ut eam.</p>
                    </div>
                </div>
            </div>
        </div>
    </div>
</div>

编辑：列只设置为大，所以确保窗口从远到右足够大。

你的意思是左：p。.这就是我看到的：如果你用css创建一个小提琴链接。.人们很可能会快速响应，你会得到答案。
