本文算是bootstrap学习使用的年底大总结，供大家参考，具体内容如下
bootstrap框架
bootstrap学习从现在开始，前端开发框架bootstrap，可大大简化网站开发过程，从而深受广大开发者的喜欢。
<!doctype html>
<html lang="zh-cn"><!-- 语言设置 -->
<head>
<meta charset="utf-8">
<meta http-equiv="x-ua-compatible" content="ie=edge">
<meta name="viewport" content="width=device-width, initial-scale=1"><!-- 浏览器缩放 -->
<title>bootstrap</title>
<!-- bootstrap -->
<link href="css/bootstrap.min.css" rel="stylesheet">
<!-- html5 shim and respond.js for ie8 support of html5 elements and media queries -->
<!-- warning: respond.js doesn't work if you view the page via file:// -->
<!--[if lt ie 9]>
<script src="http://cdn.bootcss.com/html5shiv/3.7.2/html5shiv.min.js"></script>
<script src="http://cdn.bootcss.com/respond.js/1.4.2/respond.min.js"></script>
</head>
<body>
<h1>你好</h1>
<!-- jquery (necessary for bootstrap's javascript plugins) -->
<script src="http://cdn.bootcss.com/jquery/1.11.1/jquery.min.js"></script>
<!-- include all compiled plugins (below), or include individual files as needed -->
<script src="js/bootstrap.min.js"></script>
</body>
</html>
导航
导航对于一位前端人员来说并不陌生。可以说导航是一个网站重要的元素组件之一，可以便于用户查找网站所提供的各项功能服务。
<nav class="nabber navbar-default" role="navigation"><!--导航条、默认样式、role定义内容是一个导航条-->
<div class="container-fluid"><!--container居中固定宽度、c-f自适应大小的导航条-->
<div class="navbar-header">
<!--在响应式浏览器宽度小于一定值时，显示按钮-->
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
<span class="sr-only">toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<!--logo图标-->
<a class="navbar-brand" href="#">brand</a>
</div>
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1"><!--包裹代码，在宽度大于一定值时，button和此代码是没有作用的-->
<!--导航条导航项目-->
<ul class="nav navbar-nav">
<li class="active"><a href="#">a</a></li>
<li><a href="#">a</a></li>
</ul>
</div>
</div>
</nav>
.navbar-inverse:改变导航条的背景颜色
.container:居中显示
固定导航条会遮盖页面内容，解决办法设置body的*padding-top*
下拉菜单
小伙伴们注意，在bootstrap框架中的下拉菜单组件是一个独立的组件。
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">下拉菜单<span class="caret"></span></a>
<ul class="dropdown-menu" role="menu">
<li><a href="#">action</a></li>
<li><a href="#">another action</a></li>
<li><a href="#">something else</a></li>
<li class="divider"></li>
<li><a href="#">linkkk/a></li>
</ul>
</li>
data属性api可以使用所有的bootstrap插件
轮播广告（carousel）
<div id="carousel-example-generic" class="carousel slide" data-ride="carousel">
<!--底部导航点。。。-->
<ol class="carousel-indicators">
<li data-target="#carousel-example-generic" data-slide-to="0"></li>
<li data-target="#carousel-example-generic" data-slide-to="1" class="active"></li>
<li data-target="#carousel-example-generic" data-slide-to="2"></li>
</ol>
<!--轮播广告内容-->
<div class="carousel-inner" role="listbox">
<div class="item active">
<img src="…">
<div class="carousel-caption">……</div>
</div>
<div class="item active">
<img src="…">
<div class="carousel-caption">……</div>
</div>
</div>
<!--左右箭头-->
<a class="left carousel-control" href="#carousel-example-generic" role="button" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left"></span>
<pan class="sr-only">previous</span>
</a>
<a class="right carousel-control" href="#carousel-example-generic" role="button" data-slide="next">
<span class="glyphicon glyphicon-chevron-right"></span>
<pan class="sr-only">next</span>
</a>
</div>
.data-slide-to索引，指向轮播广告的内容，从0开始
.carousel设置广告框的样式(高度、背景色)
.carousel .item设置广告框的样式(高度、背景色)
栅格系统布局
<div class="container">
<div class="row">
<div class="col-md-4">.col-md-4</div>
<div class="col-md-4">.col-md-4</div>
<div class="col-md-4">.col-md-4</div>
</div>
</div>

<li><a href="#profile" role="tab" data-toggle="tab">profile</a></li>
<li><a href="#messages" role="tab" data-toggle="tab">messages</a></li>
<li><a href="#settings" role="tab" data-toggle="tab">settings</a></li>
