如何对齐这些引导程序表单元素

我是bootstrap学习的初学者，并希望在bootstrap中对齐这些元素。当我没有添加任何图标时，它运行良好。但是如果我添加任何输入字段的任何图标，那么对齐会像下面给出的图一样被破坏。 enter image description here

这是代码：

<!DOCTYPE html>
<html lang="en">
<head>
  <title>Leave Form</title>
  <meta charset="utf-8">

输入组：不要与其他组件混合

  

不要将表单组或网格列类直接与输入混合使用   组。而是将输入组嵌套在表单组或内部   与网格相关的元素。

因为您要将输入组与列混合，请参阅Docs和正在运行的代码段。

答案 1 :(得分：0)

所有关于对齐和间距（边距和填充）。 例如。在“从日期：”行中，你有“”和“输入组”的css使“padding-left：0”因为它的对齐方式不同。 您可以在Mozilla中使用Firebug插件来查看和更改浏览器本身的CSS。
