css - 如何在 Bootstrap 4 中的输入字段旁边设置按钮？

Question

我有带有标签和输入字段的表单组。我想将按钮放在同一行的输入字段旁边。这是我的代码示例:

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous">
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.css">
<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.9/umd/popper.min.js" integrity="sha384-ApNbgh9B+Y1QKtv3Rn7W3mgPxhU9K/ScQsAP7hUibX39j7fakFPskvXusvfa0b4Q" crossorigin="anonymous"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js" integrity="sha384-JZR6Spejh4U02d8jOt6vLEHfe/JQGiRRSQQxSfFWpi1MquVdAyjUar5+76PVCmYl" crossorigin="anonymous"></script>

<div class="form-row">
  <div class="form-group col-8"><label for="date">Date:</label>
    <div class="input-group date"><input class="form-control" type="text" name="date" id="date" value="" placeholder="Enter Date"><span class="input-group-append"><span class="input-group-text"><i class="fa fa-calendar"></i></span></span>
    </div>
  </div>
  <div class="col-4 pt-4"><button type="button" class="btn btn-secondary btn-sm">Reset Date</button></div>
</div>

在我的示例中，您会看到按钮与输入字段不在同一行。有没有办法让它们在同一条线上(垂直高度)？谢谢。

<div class="form-row">
  <div class="form-group col-8"><label for="date">Date:</label>
    <div class="input-group date"><input class="form-control" type="text" name="date" id="date" value="" placeholder="Enter Date"><span class="input-group-append"><span class="input-group-text"><i class="fa fa-calendar"></i></span></span>
<button type="button" class="btn btn-secondary btn-sm" style="margin-left:5px">Reset Date</button>
    </div>
  </div>
 
</div>

备选方案:

你可以给按钮一个 margin-top 像 style="margin-top:10px"
