You can have two solutions here with the property display.

您可以在这里使用属性有两个解决方案display。

• One with inline-block:

  .col-md-12 column {  
     text-align:center;
  }
  .col-md-12 column form {
     display:inline-block;
  }
  

• Two with table:

  .col-md-12 column form {
     display:table;
     margin:auto;
  }
  

• 一个inline-block：

  .col-md-12 column {  
     text-align:center;
  }
  .col-md-12 column form {
     display:inline-block;
  }
  

• 两个table：

  .col-md-12 column form {
     display:table;
     margin:auto;
  }
  

If you have a fixed widthfor the form you only need to add the margin:auto

如果你有一个固定width的表单，你只需要添加margin:auto

Give your form a class

给你的表格上课

<form role="form" class="myForm">

and add the following style to it

并为其添加以下样式

.myForm
{
    width: 480px;
    margin-left: auto;
    margin-right: auto;
}

and creating the style declaration:

并创建样式声明：

.center{margin:0px auto;}

keeping in mind that .centermust have a set width that is less than the width of it's container.

请记住，它.center的设置宽度必须小于其容器的宽度。

Hope that helps.
