twitter-bootstrap - 水平表格 : Text Input next to label not working

Question

我试图让标签与 Bootstrap 4 水平形式的文本框位于同一行。似乎不起作用。文本框始终显示在下一行。非常感谢任何帮助。

<div class="form-group form-group-sm col-sm-6">
  <label for="first_name" class="col-form-label">First Name</label>
  <div>
    <input type="text" class="form-control" id="first_name" name="first_name">
  </div>
</div>

Answer 1

col-* 必须在 .row 中。在标签和输入包装器上使用网格列类...
