Bootstrap的基本使用(css、js文件的引入)

使用Bootstrap需要引入官方的文件

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">  
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <title>Bootstrap3示例</title>	
  <link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
	
<!-- 这里是具体的网页内容 -->

  <!-- bootstrap的核心js文件 -->
  <script src="https://cdn.bootcss.com/jquery/1.12.4/jquery.min.js"></script>
  <script src="https://cdn.bootcss.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</body>
</html>

如果更完善一点的话,参照官网是:

<!DOCTYPE html>
<html lang="zh-CN">
<head>
  <meta charset="utf-8">  
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <meta name="description" content="我是前端开发者">
  <meta name="keywords" content="javascript,vueJS,Jquery,AngularJS,HTML5,CSS3">
  <meta name="author" content="李金芝">
  <title>Bootstrap3示例</title>	
  <link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
	
<!-- 这里是具体的网页内容 -->

<!-- bootstrap的核心js文件 -->
<script src="https://cdn.bootcss.com/jquery/1.12.4/jquery.min.js"></script>
<script src="https://cdn.bootcss.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</body>
</html>
