一个前端开发的框架,Bootstrap,来自 Twitter,是目前很受欢迎的前端框架。Bootstrap 是基于 HTML、CSS、JavaScript 的,它简洁灵活,使得 Web 开发更加快捷。
需下载以下三个文件并导入html中:
<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">
<title>Bootstrap HelloWorldtitle>
<link href="css/bootstrap.min.css" rel="stylesheet">
<script src="js/jquery-3.2.1.min.js">script>
<script src="js/bootstrap.min.js">script>
head>
<body>
<h1>你好,世界!h1>

html>
同一套页面可以兼容不同分辨率的设备。
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。
1. 定义容器。(相当于之前的table)
* 容器分类:
1. container:两边留白
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 (≥992px)
4. lg:大屏幕 大桌面显示器 (≥1200px)
注:
- 一行中如果格子数目超过12,则超出部分自动换行。
- 栅格类属性可以向上兼容。栅格类适用于与屏幕宽度大于或等于分界点大小的设备。
- 如果真实设备宽度小于了设置栅格类属性的设备代码的最小值,会一个元素沾满一整行。
* 按钮:class="btn btn-default"
* 图片:
* class="img-responsive":图片在任意尺寸都占100%
* 图片形状
