html - 如何在 Bootstrap 4 中使每一列的高度相等？

Question

看看这张照片:

第二列在右边，看起来高度不等于第一列我需要弄清楚第二列应该如何获得与第一列相同的高度。

我的 HTML:

<div class="row"">
  <div class="col-8">
    <div class="row">
      <div class="col-12 mb-2">
        <div class="imgcontainer">
          <img src="https://loremflickr.com/1280/720" class="img-fluid" alt="Picture">
          <div class="top-left">Top Left</div>
        </div>
      </div>
      <div class="col-12">
        <div class="imgcontainer">
          <img src="https://loremflickr.com/1280/720" class="img-fluid" alt="Picture">

      </div>
    </div>
  </div>
  <div class="col-4">

使用 flexbox utils 制作右列 display:flex, flex-direction: column...

<div class="container-fluid">
    <div class="row">
        <div class="col-8">
            <div class="row">
                <div class="col-12 mb-2">
                    <div class="imgcontainer">
                        <img src="https://loremflickr.com/1280/720" class="img-fluid" alt="Picture">
                        <div class="top-left">Top Left</div>
                    </div>
                </div>
                <div class="col-12">
                    <div class="imgcontainer">
                        <img src="https://loremflickr.com/1280/720" class="img-fluid" alt="Picture">

                    </div>
                </div>
            </div>
        </div>
        <div class="col-4 d-flex flex-column">
