【中文标题】在移动设备上将 Bootstrap 布局从内联表单更改为网格【英文标题】：Change Bootstrap layout from inline form to grid on mobile device 【发布时间】：2016-08-21 22:02:39 【问题描述】：我有一个复杂的 Web 表单，其中一行包含许多字段。 Bootstrap 内联表单在大屏幕上效果很好。但是，要求是使页面具有响应性，以便内联表单在平板电脑和手机等较小的屏幕上转换为 3 列网格布局。
大屏内联表单：
手机屏幕上的必需布局
有可能吗？这是针对 Bootstrap 3 的。
非常感谢任何提示！
代码片段：

【问题讨论】：
我什么都试过了。 SO一直是最后的手段。我不是要求有人为我编码，为了记录。我相信其他一些人可能面临类似的情况。如果@Paulie_D 无法提供有关如何解决问题的任何提示，请不要回来投反对票。 只尝试显示顶部屏幕截图的内联表单布局，因此我故意模糊了文本。如果有人发现它令人困惑，我深表歉意。应该使用whiteout。是否必须给出代码 sn-p 才能理解问题？ 相同的结果...我们不知道什么元素是什么，以及它们应该如何定位在之前/之后。这就是为什么我们要求您使用代码进行演示...这样我们就可以看到您进行更改时发生的情况。 添加了代码片段。谢谢你。屏幕截图将被编辑以反映代码。 你能分享你的 CSS 吗？您正在使用一些自定义类。 【参考方案1】：试试这个。使用 col-md-push-* 和 col-md-pull-*
更新 JSFIDDLE
这里在form-group类和样式之前使用了form-inline类
.form-inline .form-control
width: 100%;
.nopadding
padding: 0px 2px 0px 0px !important;
margin: 0px !important;

不是这样的。请在发布解决方案之前阅读问题。原始布局是 INLINE。 Chensformers，我更新了我的代码..请查看我上面的片段 在属性中使用 0 时省略单位。 0px, 0pt, 0%, 0em, 0rem 等等。所有这些都给出了相同的结果，即 0。【参考方案2】：我修改了您的一些 html 标记，删除了一些内联样式并添加了一些类。
这就是您要查找的内容：
.myform
margin-top: 10px;
.myform fieldset
padding: 10px 20px;
background-color: #F7F7F7;
.myform .form-group
display: block;
.myform input,
.myform select
min-width: 100%;
border-radius: 0;
.myform .double-input
margin: 0;
.myform .double-input div[class^='col-'],
.myform .double-input div[class*=' col-']
padding-left: 0;
.myform .double-input:first-child div[class^='col-'],
.myform .double-input:first-child div[class*=' col-']
padding: 0;
@media (min-width: 992px)
.control-label
text-align: left;
display: block;
.myform .double-input:first-child div[class^='col-'],
.myform .double-input:first-child div[class*=' col-']
padding-right: 3px;
@media (max-width: 992px)
.myform input,
.myform select
border-top: 0;
border-right: 0;
border-left: 0;
#fName
border-right: 1px solid #ccc;
#gender
