@media (min-width: 576px) { ... }

// Medium devices (tablets, 768px and up)
@media (min-width: 768px) { ... }

我试图删除大屏幕-播放，但它不工作。最后是类行justify-content-md-center影响了，但我不知道如何修复它。

<div class="container-fluid">

    <div class="col-md-auto">

    <div class="col-md-auto">

    </div>

    <div class="col-md-auto">

      </div>

      <div class="col-md-auto">
        <a href="">
          <img src="brand-5.jpg" alt="">

          <img src="brand-4.jpg" alt="">
        </a>
      </div>

  </div>

部分“row justify-content-md-center”需要在容器流体内部，以便占据100%的屏幕宽度。把它想象成一个盒子，你必须用'container'或'container-fluid'指定区域，然后放置你的元素。
