我正在使用bootstrap。

Answer 1

演示http://bootply.com/103569

可以使用像：

这样的偏移量

<div class="container">
<div class="row clearfix">
    <div class="col-md-6 col-md-offset-3 column">
        <form role="form">
            <div class="form-group">
                 <label for="exampleInputEmail1">Email address</label><input type="email" class="form-control" id="exampleInputEmail1" />
            </div>
            <div class="form-group">
                 <label for="exampleInputPassword1">Password</label><input type="password" class="form-control" id="exampleInputPassword1" />
            </div>
            <div class="form-group">
                 <label for="exampleInputFile">File input</label><input type="file" id="exampleInputFile" />
                <p class="help-block">
                    Example block-level help text here.
                </p>
            </div>
            <div class="checkbox">
                 <label><input type="checkbox" /> Check me out</label>
            </div> <button type="submit" class="btn btn-default">Submit</button>
        </form>
    </div>
</div>
<div class="row clearfix">
    <div class="col-md-12 column">
    </div>
</div>
</div>

或

<div class="container">
<div class="row clearfix">
    <div class="col-md-12 column">
    <div class="col-md-6 col-md-offset-3 column">
        <form role="form">
            <div class="form-group">
                 <label for="exampleInputEmail1">Email address</label><input type="email" class="form-control" id="exampleInputEmail1" />
            </div>
            <div class="form-group">
                 <label for="exampleInputPassword1">Password</label><input type="password" class="form-control" id="exampleInputPassword1" />
            </div>
            <div class="form-group">
                 <label for="exampleInputFile">File input</label><input type="file" id="exampleInputFile" />
                <p class="help-block">
                    Example block-level help text here.
                </p>
            </div>
            <div class="checkbox">
                 <label><input type="checkbox" /> Check me out</label>
            </div> <button type="submit" class="btn btn-default">Submit</button>
        </form>
    </div>
    </div>
</div>
</div>

Answer 2

您可以在此处使用属性display获得两个解决方案。

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;
}

如果您对表单有固定的width，则只需添加margin:auto

Answer 3

给你的表格一个班级

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

并添加以下样式

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

Answer 4

我会尝试添加

class="center"

到

<form role="form">

以

结尾

<form role="form" class="center">

并创建样式声明：

.center{margin:0px auto;}

请注意，.center的设定宽度必须小于其容器的宽度。

希望有所帮助。
