Bootstrap 4 列的弹性对齐

Question

我完全糊涂了。我弄清楚了这一点，然后刷新了 jsfiddle，解决方案以某种方式发生了变化。我有一排两列。我无法让两列在同一行上对齐。我尝试使用 justify-content-around 但它不起作用。帮助将不胜感激。

<div class="container-fluid">
  <div class="d-flex flex-row justify-content-around my-flex-container">
    <div class="d-flex flex-column my-flex-container-column">
      <div class="flex-row my-flex-container">Row 1</div>
      <div class="flex-row my-flex-container">Row 2</div>
      <div class="flex-row my-flex-container">Row 3</div>
      <div class="flex-row my-flex-container">Row 4</div>
    </div>  
    <div class="d-flex flex-column my-flex-container-column">
      <div class="d-flex flex-row my-flex-container">
        <div class="flex-column my-flex-container-column">
           <div class="flex-row my-flex-container">Row 1
           </div>
           <div class="flex-row my-flex-container">Row 2
           </div>
        </div>
      </div>
      <div class="d-flex flex-row flex-1 my-flex-container">
        <div class="my-auto">ROW 3</div>
      </div>

    </div>
  </div>
</div>

您需要将您的 Bootstrap 版本从 Alpha 版本更新到 Beta 版本，您可以获得它 here。

  .my-flex-container {
    border: 2px solid green;
  }
   .my-flex-container-column {
    border: 2px solid green;
  }
  .flex-1{
    flex: 1;
  }

<div class="container-fluid">
  <div class="d-flex flex-row justify-content-around my-flex-container">
    <div class="d-flex flex-column my-flex-container-column">
      <div class="flex-row my-flex-container">Row 1</div>
      <div class="flex-row my-flex-container">Row 2</div>
      <div class="flex-row my-flex-container">Row 3</div>
      <div class="flex-row my-flex-container">Row 4</div>
    </div>  
    <div class="d-flex flex-column my-flex-container-column">
      <div class="d-flex flex-row my-flex-container">
        <div class="flex-column my-flex-container-column">
           <div class="flex-row my-flex-container">Row 1
           </div>
           <div class="flex-row my-flex-container">Row 2
           </div>
        </div>
      </div>
      <div class="d-flex flex-row flex-1 my-flex-container">
        <div class="my-auto">ROW 3</div>
      </div>
 
    </div>
