自版本 2.3.2 起，Bootstrap 提供了两种类型的网格，默认网格系统和流动网格系统。默认的网格系统是 940px 宽和 12 列。本文主要讲解第一种。
<!DOCTYPE html><html> <head> <title>Fixed layout example with Bootstrap</title> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <!-- Bootstrap --> <link href="bootstrap/CSS/bootstrap.min.css" rel="stylesheet" media="screen"> </head> <body> <script src="http://code.jquery.com/jquery.js"></script> <script src="bootstrap/js/bootstrap.min.js"></script> </body></html>View Code
Bootstrap 使用 CSS 的 class "row" 来创建水平行，使用 CSS 的 class "spanx"（x 的值从 1 到 12）来创建垂直列。通过这两个就可以创建一个三列的网格（每一列包含一些文本内容），HTML 如下所示

创建网格的语法如下：
<div class="row"><div class="spanx">inline elements like span, block level elements like p, div.</div> <div>
