水平表格:标签旁边的文字输入无效

Question

我试图将标签与Bootstrap 4水平形式的文本框放在同一行.似乎没有用.文本框始终显示在下一行中.任何帮助是极大的赞赏.

<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

的col-*必须是.row.在标签上使用网格列类并输入包装器...
