html - 将小元素放在标题下方，但保持垂直对齐

Question

我有下面代码的布局，其中每个列表项都有一个标题“Item 0”，下面有一个带有文本“Description Item 0”的小标签，然后是右侧的两个选择菜单。我想要原样的布局，唯一的问题是我想要标题“元素 0”下方的小标签“描述元素 0”，但它不起作用。你知道如何将小标签放在标题“Item 0”下方并保持元素的垂直对齐吗？

HTML代码:

<div class="container py-5">
  <div class="row no-gutters">
    <div class="col-12 col-lg-8">
      <div class="card">
        <div class="card-header">
          <h5 class="text-heading-blue mb-0 font-weight-semi-bold">Title</h5>
        </div>
        <div class="card-body">
          <ul class="list-group">
            <li class="list-group-item d-flex justify-content-between align-items-center">
              <span>Item 0</span>
              <span>Description Item 0</span>
              <form>
                <select class="custom-select form-control" style="width:100px;">
                  <option selected="">0</option>
                  <option>1</option>
                  <option>2</option>
                </select>
              </form>
              <form>
                <select class="custom-select form-control" style="width:100px;">                  <option selected="">0</option>
                  <option>1</option>
                  <option>2</option>
                </select>
              </form>
            </li>

          </ul>
        </div>
        <div class="card-footer">
          <button type="button" class="float-right btn">Next</button>
        </div>
      </div>
    </div

你为什么不把这两个元素放在同一个<span>并使用 <br /> ？

<span>Item 0<br />Description Item 0</span>
