html - 想要将营销 div 居中并在其周围放一个框 - 使用 Bootstrap

Question

我正在使用 bootstrap 3，我正在尝试将营销 div 居中并在其周围放一个框。我想将营销部分保持在中心位置。

.box 只是一个带边框的简单框。

这是我的代码:

<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>

它把盒子向右延伸得太远了，我不明白为什么它不在两边。

看起来您的列并没有完全加起来。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>
