twitter-bootstrap - 如何在 Bootstrap 中将我的 SignUp From 居中？

Question

我试图将这个 Bootstrap form 居中.

我希望输入字段和按钮与 DOM 的中心对齐。

<div>                
    <div class = "container">                    
        <div>                             
            <form class = "">        
                <div  class = "row">          
                    <div class = "form-group">          
                        <input  type = "email" class = "form-control input-lg" placeholder = "Enter email address "/>        
                    </div>   
                </div>
                <div  class = "row">              
                    <div class = "form-group">
                        <input  type = "password" class = "form-control input-lg" placeholder = "Enter password" /> 
                    </div>            
                    <input type = "submit" class = "btn btn-info btn-lg"/>
                </div>                              
            </form> 
        </div> 
    </div>  
</div>

尝试使用这个

<div>
  <div class="container">
    <div align="">
      <form class="text-center">
        <div class="">
          <div class="form-group">
            <input type="email" class="form-control input-lg" placeholder="Enter email address " />
          </div>
        </div>
        <div class="">
          <div class="col-sm-4">
          </div>
          <div class="form-group">
            <input type="password" class="form-control input-lg" placeholder="Enter password" />
          </div>
          <input type="submit" class="btn btn-info btn-lg" />
        </div>
      </form>
    </div>
  </div>
</div>
