一、前言
1、介绍
Bootstrap 是最受欢迎的 HTML、CSS 和 JS 框架，用于开发响应式布局、移动设备优先的 WEB 项目。
Bootstrap它是基于jQuery，也就意味着你在用bootstrap要先导入jQuery文件
为所有开发者、所有应用场景而设计。
Bootstrap 让前端开发更快速、简单。
所有开发者都能快速上手、所有设备都可以适配、所有项目都适用。
2、为什么要用Bootstrap？
在Bootstrap出现之前：
命名：重复、复杂、无意义（想个名字费劲）
样式：重复、冗余、不规范、不和谐
页面：错乱、不规范、不和谐
在使用Bootstrap之后： 各种命名都统一并且规范化。 页面风格统一，画面和谐。
3、下载链接：
我们使用V3版本的Bootstrap，我们下载的是用于生产环境的Bootstrap。
二、全局css样式
1、布局容器
<div class="container "></div> 左右有固定留白 <div class="container-fluid c1"></div> 全屏展示
2、栅格系统
栅格系统用于通过一系列的行（row）与列（column）的组合来创建页面布局
一个row就表示一行(这一行默认给你均分成了12份,每一份你还可以均分成12份)
首先使用bootstrap先写一个布局容器
<div class='container'></div>
<div class='container-fluid'></div>
语法：
<div class="container">
<div class="row"> 一行
<div class="col-md-6 c1"></div> 控制你占当前行的多少列
借助谷歌浏览器自动切换手机或电脑屏幕，只需要加一个col-xs-6生成对应的布局
1、标题相关
标题
<h1>一级标题36px</h1> <h2>二级标题30px</h2> <h3>三级标题24px</h3> <h4>四级标题18px</h4> <h5>五级标题14px</h5> <h6>六级标题12px</h6> <!--除了使用h标签，Bootstrap内置了相应的全局样式--> <!--内联标签应用标题样式--> <span class="h1">一级标题36px</span> <span class="h2">二级标题30px</span> <span class="h3">三级标题24px</span> <span class="h4">四级标题18px</span> <span class="h5">五级标题14px</span> <span class="h6">六级标题12px</span>
副标题
<!--一级标题中嵌入小标题--> <h1>一级标题<small>小标题</small></h1>
2、文本对齐
<!--文本对齐--> <p class="text-left">文本左对齐</p> <p class="text-center">文本居中</p> <p class="text-right">文本右对齐</p>
3、文本大小写
<!--大小写--> <p class="text-lowercase">Lowercased text.</p> <p class="text-uppercase">Uppercased text.</p> <p class="text-capitalize">Capitalized text.</p>
4、表格
5、状态类
6、表单
内联表单
表单状态
带图标的表单
7、按钮
<a class="btn btn-default" href="#" role="button">Link</a> <button class="btn btn-default" type="submit">Button</button> <input class="btn btn-default" type="button" value="Input"> <input class="btn btn-default" type="submit" value="Submit">
按钮样式
<!-- Standard button --> <button type="button" class="btn btn-default">（默认样式）Default</button> <!-- Provides extra visual weight and identifies the primary action in a set of buttons --> <button type="button" class="btn btn-primary">（首选项）Primary</button> <!-- Indicates a successful or positive action --> <button type="button" class="btn btn-success">（成功）Success</button> <!-- Contextual button for informational alert messages --> <button type="button" class="btn btn-info">（一般信息）Info</button> <!-- Indicates caution should be taken with this action --> <button type="button" class="btn btn-warning">（警告）Warning</button> <!-- Indicates a dangerous or potentially negative action --> <button type="button" class="btn btn-danger">（危险）Danger</button> <!-- Deemphasize a button by making it look like a link while maintaining button behavior --> <button type="button" class="btn btn-link">（链接）Link</button>
按钮大小
<p> <button type="button" class="btn btn-primary btn-lg">（大按钮）Large button</button> <button type="button" class="btn btn-default btn-lg">（大按钮）Large button</button> </p> <p> <button type="button" class="btn btn-primary">（默认尺寸）Default button</button> <button type="button" class="btn btn-default">（默认尺寸）Default button</button> </p> <p> <button type="button" class="btn btn-primary btn-sm">（小按钮）Small button</button> <button type="button" class="btn btn-default btn-sm">（小按钮）Small button</button> </p> <p> <button type="button" class="btn btn-primary btn-xs">（超小尺寸）Extra small button</button> <button type="button" class="btn btn-default btn-xs">（超小尺寸）Extra small button</button> </p>
8、图片
<img src="..." class="img-responsive" alt="Responsive image">
图片形状
<img src="..." alt="..." class="img-rounded"> <img src="..." alt="..." class="img-circle"> <img src="..." alt="..." class="img-thumbnail">
9、辅助类
文本颜色
<p class="text-muted">...</p> <p class="text-primary">...</p> <p class="text-success">...</p> <p class="text-info">...</p> <p class="text-warning">...</p> <p class="text-danger">...</p>
背景颜色
<p class="bg-primary">...</p> <p class="bg-success">...</p> <p class="bg-info">...</p> <p class="bg-warning">...</p> <p class="bg-danger">...</p>
关闭按钮
<button type="button" class="close" aria-label="Close"><span aria-hidden="true">×</span></button>
下拉三角
<span class="caret"></span>
快速浮动
<div class="pull-left">...</div> <div class="pull-right">...</div>
内容块居中
<div class="center-block">...</div>
清除浮动
<!-- Usage as a class --> <div class="clearfix">...</div>
显示与隐藏
<div class="show">...</div> <div class="hidden">...</div>
三、常用Bootstrap组件
1、字体图标
使用Font Awesome图标前先导入其css文件
<link rel="stylesheet" href="https://cdn.bootcss.com/font-awesome/4.7.0/css/font-awesome.min.css">
可以下载到本地使用
<link rel="stylesheet" href="fontAwesome/css/font-awesome.min.css">
2、下拉菜单
3、按钮组
<div class="btn-group" role="group" aria-label="..."> <button type="button" class="btn btn-default">Left</button> <button type="button" class="btn btn-default">Middle</button> <button type="button" class="btn btn-default">Right</button> </div>
按钮工具栏
把一组 <div class="btn-group"> 组合进一个 <div class="btn-toolbar"> 中就可以做成更复杂的组件。
<div class="btn-toolbar" role="toolbar" aria-label="..."> <div class="btn-group" role="group" aria-label="...">...</div> <div class="btn-group" role="group" aria-label="...">...</div> <div class="btn-group" role="group" aria-label="...">...</div> </div>
4、输入框组
<div class="col-lg-6"> <div class="input-group"> <input type="text" class="form-control" placeholder="Search for..."> <span class="input-group-btn"> <button class="btn btn-default" type="button">Go!</button> </span> </div><!-- /input-group --> </div><!-- /.col-lg-6 -->
