我在移动设备上具有以下div布局：

  <div class="col-md-8">
    <img src="https://dummyimage.com/400x100/000/fff&text=1" alt="" class="w-100" />
  </div>
  <div class="col-md-4">
    <img src="https://dummyimage.com/400x800/111/fff&text=2" alt="" class="w-100" />
  </div>
  <div class="col-md-8">
    <img src="https://dummyimage.com/400x100/222/fff&text=3" alt="" class="w-100" />
  </div>
  <div class="col-md-8">
    <img src="https://dummyimage.com/400x100/333/fff&text=4" alt="" class="w-100" />
  </div>
  <div class="col-md-8">
    <img src="https://dummyimage.com/400x300/444/fff&text=5" alt="" class="w-100" />
  </div>
  <div class="col-md-8">

Answer 1

唯一的方法是使用d-md-block和float实用程序在md上禁用disable flex ...

<div class="container">
    <div class="row d-md-block">
        <div class="col-md-4 float-right">
            <img src="https://dummyimage.com/400x100/000/fff&text=1" alt="1" class="w-100" />
        </div>
        <div class="col-md-8 float-left">
            <img src="https://dummyimage.com/400x800/111/fff&text=2" alt="2" class="w-100" />
        </div>
        <div class="col-md-4 float-right">
            <img src="https://dummyimage.com/400x100/222/fff&text=3" alt="3" class="w-100" />
        </div>
        <div class="col-md-4 float-right">
            <img src="https://dummyimage.com/400x100/333/fff&text=4" alt="4" class="w-100" />
        </div>
        <div class="col-md-4 float-right">
            <img src="https://dummyimage.com/400x300/444/fff&text=5" alt="5" class="w-100" />
        </div>
        <div class="col-md-4 float-right">
            <img src="https://dummyimage.com/400x100/555/fff&text=6" alt="6" class="w-100" />
        </div>
        <div class="col-md-4 float-right">
            <img src="https://dummyimage.com/400x200/666/fff&text=7" alt="7" class="w-100" />
        </div>
        <div class="col-md-8 float-left">
