59 basic验证的WebRequest/WebResponse

<table>
  <tbody>
    <tr>
      <td>Field</td>
      <td>@Html.TextBox("Field")</td>
    </tr>
    <tr>
      <td>Field 2</td>
      <td>@Html.TextBox("Field2")</td>
    </tr>
  </tbody>
</table>

产生如下格式：

Field    <TextBox>
Field    <TextBox>

大多数移动设计都是这样设计的：

Field
<TextBox>
Field
<TextBox>

这是我需要做的事情,因为我的一些表单太长而无法在移动浏览器中显示.有没有简单的方法来设置它？也许有一种方法可以让每个单元格在一个新行上渲染,这对我有用吗？是否支持跨浏览器？

还是需要重新设计？

谢谢.

@media (max-width:40em) {
    table,thead,tbody,tfoot,th,td,tr { display:block; }
    tr + tr { margin-top:1em; }
}
