JavaWeb - BootStrap

1.BootStrap了解

  概念:一个前端开发的框架

    *框架:一个半成品的软件,开发人员可以在框架基础上,再进行开发,简化编码

    *好处:

      1.定义了很多的css样式和js插件。我们开发人员直接可以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

2.快速入门

  1.下载BootStrap

  2.在项目中将这三个文件夹复制

  3.创建html页面,引入必要的资源文件

 

<!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 (necessary for Bootstrap's JavaScript plugins) -->
<script src="js/jquery-3.2.1.min.js"></script>
<!-- Include all compiled plugins (below), or include individual files as needed -->
<script src="js/bootstrap.min.js"></script>
</body>
</html>
模板

 

3.响应式布局

  *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:将一行平均分成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

      容器分类:

        1.container : 两边有留白

        2.container-fluid : 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 (>= 992 px)

        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出12,则超出部分自动换行

    2.栅格类属性可以向上兼容  比如给手机设置一个div占4格 则sm md lg 都可以兼容 都是一行三个div

    3.如果真实设备宽度小于了栅格类属性的设备代码的最小值,会一个元素占满一整行

 

4.CSS样式和JS插件

  全局CSS样式:

    *按钮 :class="btn btn-default"  default可以修改
