引导错误：在移动/笔记本电脑上工作，但不是台式机

Question

我是前端开发和修改登录页面上现有表单（添加额外列）的新手。当我添加此列时，它可以在所有设备（桌面除外）上正常呈现。

我希望得到有关可能原因以及如何解决此问题的指示。

下面是我的代码副本：

    <div class="fields">
                        <div class="col-lg-4 col-md-4 col-sm-4 lbl"><label>First Name*</label></div>
                        <div class="col-lg-8 col-md-8 col-sm-8 fld"><input type="text" maxlength="40" name="fname" id="fname" required/></div>
                    </div>
                    <div>

分享代码或使用

在引导中使用

class="col-lg-14 col-md-14 col-sm-5 col-xs-12"

桌面使用 lg 和 md
