Bootstrap水平表单不起作用

标签： html css twitter-bootstrap

我试图为我的laravel应用程序构建一个带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：

form is displayed on the left halve of the page

表单显示在页面的左半部分。有任何想法吗？优选地，表格应该在页面上居中。

您可以尝试以下引导代码：

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

所以，基本的想法是将所有列除以3意味着总共有12个自举列，如果将它除以4，它会给你3列。然后把你的div放在中间列。意思是col-md-4生成一列4个引导列。

试试这个：我尝试过使用IntelliJ Idea，它在浏览器中运行正常。让我知道什么不起作用？
