html - 如何使用 bootstrap 排列输入字段？

Question

我认为我不太了解 bootstrap 如何与网格一起工作。我希望 name 和 actual 字段匹配，除非屏幕大小为 xs，因此每个字段都是自己的行。对于每一行，我希望文本框始终对齐。

这是我尝试过的。

如果有人能帮助我扩大描述字段，则可加分 - 高度足以容纳至少 20 行新行。

这包括描述中额外的 20 个空格将此添加到您的 .css

     .col-sm-4 {
     display: inline-block;
     vertical-align: middle;
     float: none;
     }
