* 框架:一个半成品软件,开发人员可以在框架基础上,再进行开发,简化编码
* 好处:
1、定义了很多CSS样式和JS插件。我们开发人员可以直接使用这些样式和插件得到丰富的页面效果。
2、响应式布局
* 同一套页面可以兼容不同分辨率的设备。
1、下载bootstrap
2、在项目中将这三个文件夹复制进去
3、创建html页面,引入必要的资源文件(一般的话引入含min的文件,因为是压缩般的,加载速度快;没有min的适合源码阅读)
基本模板:
<!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 href="css/bootstrap.min.css" rel="stylesheet"> </head> <body> <h1>你好,世界!</h1> <!-- jQuery (Bootstrap 的所有 JavaScript 插件都依赖 jQuery,所以必须放在前边) --> <script src="js/jquery-3.2.1.min.js"></script> <!-- 加载 Bootstrap 的所有 JavaScript 插件。你也可以根据需要只加载单个插件。 --> <script src="js/bootstrap.min.js"></script> </body> </html>
* 同一套页面可以兼容不同分辨率的设备。
* 实现:依赖于栅格系统:将一行平均分为12个格子,可以指定元素占几个格子。
* 步骤:
1、定义容器。相当于之前的table
* 容器的分类:
1、container:两边留白
2、container-fluid:100% 每一种设备都是100%宽度
2、定义行。相当于之前的tr 样式:row
3、定义元素。指定该元素在不同的设备上,所占的格子数目。 样式:col-设备代号-格子数目
* 设备代号:
1、xs:超小屏幕 手机(<768px):col-xs-12
2、sm:小屏幕 平板(>=768px)
3、md:中等屏幕 桌面显示器(>=992px)
4、lg:大屏幕 大桌面显示器(>=1200px)
* 注意:
1、一行中,如果格子数目超过12,超出部分自动换行
2、栅格类属性可以向上兼容。栅格类适用于屏幕宽度大于或等于分界点大小的设备
3、如果设备宽度小于了设置栅格类属性的设备代码的最小值,会一个元素占满一整行
全局CSS样式:
* 按钮:class="btn btn-primary" 控制按钮样式
* 图片:class="img-responsive img-circle" 图片在任意尺寸都占100% 后面一个是调整图片形状(有三种)
* 表格:class="table table-bordered table-hover"
* 表单:给表单项添加:class="form-control"
组件:
* 导航条:
<nav class="navbar navbar-default"> <div class="container-fluid"> <!-- Brand and toggle get grouped for better mobile display --> <div class="navbar-header"> <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false"> <span class="sr-only">Toggle navigation</span> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </button> <a class="navbar-brand" href="#">Brand</a> </div> <!-- Collect the nav links, forms, and other content for toggling --> <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1"> <ul class="nav navbar-nav"> <li class="active"><a href="#">Link <span class="sr-only">(current)</span></a></li> <li><a href="#">Link</a></li> <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Dropdown <span class="caret"></span></a> <ul class="dropdown-menu"> <li><a href="#">Action</a></li> <li><a href="#">Another action</a></li> <li><a href="#">Something else here</a></li> <li role="separator" class="divider"></li> <li><a href="#">Separated link</a></li> <li role="separator" class="divider"></li> <li><a href="#">One more separated link</a></li> </ul> </li> </ul> <form class="navbar-form navbar-left"> <div class="form-group"> <input type="text" class="form-control" placeholder="Search"> </div> <button type="submit" class="btn btn-default">Submit</button> </form> <ul class="nav navbar-nav navbar-right"> <li><a href="#">Link</a></li> <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Dropdown <span class="caret"></span></a> <ul class="dropdown-menu"> <li><a href="#">Action</a></li> <li><a href="#">Another action</a></li> <li><a href="#">Something else here</a></li> <li role="separator" class="divider"></li> <li><a href="#">Separated link</a></li> </ul> </li> </ul> </div><!-- /.navbar-collapse --> </div><!-- /.container-fluid --> </nav>
* 分页条:
<nav aria-label="Page navigation"> <ul class="pagination"> <li> <a href="#" aria-label="Previous"> <span aria-hidden="true">«</span> </a> </li> <li><a href="#">1</a></li> <li><a href="#">2</a></li> <li><a href="#">3</a></li> <li><a href="#">4</a></li> <li><a href="#">5</a></li> <li> <a href="#" aria-label="Next"> <span aria-hidden="true">»</span> </a> </li> </ul> </nav>
