1、头部
<!DOCTYPE html>
<html>
<head>
<title>Bootstrap 101 Template</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
2、link链接入html
<link href="css/bootstrap.min.css" rel="stylesheet">
<link href="css/bootstrap.css" rel="stylesheet">
3、script的链入
<script src="js/bootstrap.min.js"></script>
里面具体的标签元素很多，讲不清楚，由流动性的框架内包含多个有编号的span框架组成：
<div class="row-fluid">
<div class="row">
<div class="span8">...</div>
<div class="span4">...</div>
</div>
<dd class="lead">Bacon ipsum dolor sit amet tri-tip pork loin ball tip frankfurter swine boudin meatloaf shoulder short ribs cow drumstick beef jowl. Meatball chicken sausage tail, kielbasa strip steak turducken venison prosciutto. Chuck filet mignon tri-tip ribeye, flank brisket leberkas.
