我如何创建此 bootstrap 网格布局？

Question

我正在尝试将此布局存档到我的页面（图片左侧），但我无法使第二个元素横跨两行。在容器 2 中，我需要插入一个图像。另外，当我最小化屏幕尺寸，使其成为智能手机屏幕尺寸时，布局需要看起来像这样（在图片的右侧）。

    <title>Hello, world!</title>
  </head>
  <body>
        <div class="row">
          <div class="col-lg-6 col-sm-12">
            <div class="row">
                <div class="col-12">1</div>
                <div class="col-12">2</div>
            </div>
          </div>
          <div class="col-lg-6 col-sm-12">
