Bootstrap将会根据你的屏幕的大小来调整HTML元素的大小 —— 强调 响应式设计的概念。

你仅需要通过添加下列代码到你的HTML开头来将Bootstrap添加到任意应用中：

<link rel="stylesheet" href="//cdn.bootcss.com/bootstrap/3.3.1/css/bootstrap.min.css"/>







<div class="container-fluid">
<link href="//fonts.gdgdocs.org/css?family=Lobster" rel="stylesheet" type="text/css">
<style>
  .red-text {
    color: red;
  }


  h2 {
    font-family: Lobster, Monospace;
  }


  p {
    font-size: 16px;
    font-family: Monospace;
  }


  .thick-green-border {
