引导水平形式不起作用

Question

我正在尝试为我的 laravel 应用程序构建一个带有引导程序的简单水平表单。这是我正在使用的代码。但它显示如下：

表单显示在页面的左半部分。有任何想法吗？表单最好位于页面的中心。

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" />
<div class="container">
  <form class="form-horizontal">
    <fieldset>

      <!-- Form Name -->
      <legend>Register</legend>

      <!-- Text input-->
      <div class="form-group">
        <label class="col-sm-6 control-label" for="name">Name</label>
        <div class="col-sm-6">
          <input id="name" name="name" placeholder="Name" class="form-control input-md" required="" type="text">
        </div>
      </div>

      <!-- Text input-->
      <div class="form-group">
        <label class="col-sm-6 control-label" for="email">Email</label>
        <div class="col-sm-6">
          <input id="email" name="email" placeholder="Email" class="form-control input-md" required="" type="email">
        </div>
      </div>

      <!-- Password input-->

        <label class="col-sm-6 control-label" for="password">Password</label>
        <div class="col-sm-6">

        <div class="col-sm-6">

        </div>
      </div>

    </fieldset>

<div class="container">
<div class="row">
	<div class="col-lg-8 col-md-8">
		<form class="form-horizontal">
			<fieldset>
				<!-- Form Name -->
				<legend>Register</legend>

				<!-- Text input-->
				<div class="form-group">

您可以尝试以下引导代码：

<div class="col-md-4 col-md-offset-4">your div</div>

因此，基本思想是将所有列除以 3，这意味着总共有 12 个引导列，如果将其除以 4，则得到 3 列。然后将您的 div 放在中间列。意思是 col-md-4 使一列由 4 个引导列组成。

试试这个：我已经尝试过 IntelliJ Idea，它在我的浏览器中运行良好。让我知道什么不起作用？
