bootstrap精简教程_动力节点Java学院整理

bootstrap 的学习非常简单，并且它所提供的样式又非常精美。只要稍微简单的学习就可以制作出漂亮的页面。

bootstrap提供了三种类型的下载：

1、用于生产环境的 Bootstrap

编译并压缩后的 CSS、JavaScript 和字体文件。不包含文档和源码文件。

2、Bootstrap 源码

Less、JavaScript 和字体文件的源码，并且带有文档。需要 Less 编译器和一些设置工作。

3、Sass

这是 Bootstrap 从 Less 到 Sass 的源码移植项目，用于快速地在 Rails、Compass 或只针对 Sass 的项目中引入。

其实我们不用下载bootstrap也可以使用它：

Bootstrap 中文网为 Bootstrap 专门构建了自己的免费 CDN 加速服务。基于国内云厂商的 CDN 服务，访问速度更快、加速效果更明显、没有速度和带宽限制、永久免费。

base.html

<!DOCTYPE html>
<html lang="zh-CN">
 <head>
 <meta charset="utf-8">
 <meta http-equiv="X-UA-Compatible" content="IE=edge">
 <meta name="viewport" content="width=device-width, initial-scale=1">
 <!-- 上述3个meta标签*必须*放在最前面，任何其他内容都*必须*跟随其后！ -->
 <title>Bootstrap 101 Template</title>

 <!-- Bootstrap -->
 <link rel="stylesheet" href="http://cdn.bootcss.com/bootstrap/3.3.4/css/bootstrap.min.css" rel="external nofollow" >
 
 </head>
 <body>
 <h1>你好，bootstrap！</h1>

 <!-- jQuery (necessary for Bootstrap's JavaScript plugins) -->
 <script src="http://cdn.bootcss.com/jquery/1.11.2/jquery.min.js"></script>
 <!-- Include all compiled plugins (below), or include individual files as needed -->
 <script src="http://cdn.bootcss.com/bootstrap/3.3.4/js/bootstrap.min.js"></script>
 </body>
</html>

base.html中已经引入了bootstrap，将其保存，我们就可以使用bootstrap提供的样式了。

字体图标

bootstrap默认提供了二百多个图标。我们可以通过span标签来使用这些图标：

 <h3>图标</h3> 
 <span class="glyphicon glyphicon-home"></span>
 <span class="glyphicon glyphicon-signal"></span>
 <span class="glyphicon glyphicon-cog"></span>
 <span class="glyphicon glyphicon-apple"></span>
 <span class="glyphicon glyphicon-trash"></span>
 <span class="glyphicon glyphicon-play-circle"></span>
 <span class="glyphicon glyphicon-headphones"></span>

按钮

　　<button></button>标签用于创建按钮，bootstrap提供了丰富的按钮样式。

 <h3>按钮</h3>
 <button type="button" class="btn btn-default">按钮</button>
 <button type="button" class="btn btn-primary">primary</button>
 <button type="button" class="btn btn-success">success</button>
 <button type="button" class="btn btn-info">info</button>
 <button type="button" class="btn btn-warning">warning</button>
 <button type="button" class="btn btn-danger">danger</button>
 
 <h3>按钮尺寸</h3>
 <button type="button" class="btn btn-default">按钮</button>
 <button type="button" class="btn btn-primary btn-lg">primary</button>
 <button type="button" class="btn btn-success btn-sm">success</button>
 <button type="button" class="btn btn-info btn-xs">info</button>

 <h3>把图标显示在按钮里</h3>
 <button type="button" class="btn btn-default"><span class="glyphicon glyphicon-home"></span>&nbsp;&nbsp;按钮</button>

按钮除了有默认的大小外，bootstrap还提供三个参数来调整按钮的大小，分别是：btn-lg、btn-sm和btn-xs。

下拉菜单

下拉菜单是最常见的交互之一，bootstrap提供了漂亮的样式。

  <h3>下拉菜单</h3>
 <div class="dropdown">
  <button class="btn btn-primary dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown" aria-expanded="true">
  Dropdown
  <span class="caret"></span>
  </button>
  <ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu1">
  <li role="presentation"><a role="menuitem" tabindex="-1" href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >Action</a></li>
  <li role="presentation"><a role="menuitem" tabindex="-1" href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >Another action</a></li>
  <li role="presentation"><a role="menuitem" tabindex="-1" href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >Something else here</a></li>
  <li role="presentation"><a role="menuitem" tabindex="-1" href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >Separated link</a></li>
  </ul>
 </div>

输入框

通过<input></input>标签去创建输入框。

 <h3>输入框</h3>
 <div class="input-group">
  <span class="glyphicon glyphicon-user"></span>
  <input type="text" placeholder="username">
 </div>

 <div class="input-group">
  <span class="glyphicon glyphicon-lock"></span>
  <input type="password" placeholder="password">
 </div>

导航栏

导航栏作为整个网站的指引必不可少。

 <h3>导航栏</h3>
 <nav class="navbar navbar-inverse navbar-fixed-top">
  <div id="navbar" class="navbar-collapse collapse">
   <ul class="nav navbar-nav">
   <li class="active"><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >Home</a></li>
   <li><a href="#about" rel="external nofollow" >About</a></li>
   <li><a href="#contact" rel="external nofollow" >Contact</a></li>
   <li class="dropdown">
    <a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">Dropdown <span class="caret"></span></a>
    <ul class="dropdown-menu" role="menu">
    <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >Action</a></li>
    <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >Another action</a></li>
    <li class="divider"></li>
    <li class="dropdown-header">Nav header</li>
    <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >Separated link</a></li>
    </ul>
   </li>
   </ul>
  </div><!--/.nav-collapse -->
  </div>
 </nav>

表单

人与系统之间数据的传递都需要依靠表单来完成。比如注册/登录信息的提交，查询条件的提交等。用<form></form>标签来创建表单。

 <h3>表单</h3>
 <form>
 <div class="form-group">
  <span class="glyphicon glyphicon-user"></span>
  <input type="email" id="exampleInputEmail1" placeholder="Enter email">
 </div>
 <div class="form-group">
  <span class="glyphicon glyphicon-lock"></span>
  <input type="password" id="exampleInputPassword1" placeholder="Password">
 </div>
 <div class="form-group">
  <label for="exampleInputFile">File input</label>
  <input type="file" id="exampleInputFile">
  <p class="help-block">Example block-level help text here.</p>
 </div>
 <div class="checkbox">
  <label>
  <input type="checkbox"> Check me out
  </label>
 </div>
 <button type="submit" class="btn btn-default">Submit</button>
 </form>

警告框

警告框是系统向用户传达信息和提供指引的重要手段。没有针对警告框的标签，通过bootstrap所提供的样式可以瞬间制作出漂亮的警告框。

 <h3>警告框</h3>
 <div class="alert alert-warning alert-dismissible" role="alert">
  <button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span></button>
  <strong>Warning!</strong> Better check yourself, you're not looking too good.
 </div>
 <div class="alert alert-success" role="alert">
  <a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="alert-link">success!</a>
 </div>
 <div class="alert alert-info" role="alert">
  <a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="alert-link">info!</a>
 </div>
 <div class="alert alert-warning" role="alert">
  <a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="alert-link">warning!</a>
 </div>
 <div class="alert alert-danger" role="alert">
  <a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="alert-link">danger!</a>
 </div>

进度条

系统的处理过程往往需要用户等待，进度条可以让用户感知到系统的处理过程，从而增加容忍度。

 <h3>进度条</h3>
 <div class="progress">
  <div class="progress-bar" role="progressbar" aria-valuenow="70" aria-valuemin="0" aria-valuemax="100" style="width: 60%;">
  70%
  </div>
 </div>
