============================================================
移动端自适应布局 - rem + flex 移动端适配，响应式设计
布局方式：rem 相对单位 + Flex 弹性布局 + Media Query
布局思想：
1. 使用 rem 作为尺寸单位，通过设置 html 的 font-size 实现等比缩放
2. 以 750px 设计稿为基准，JS 动态计算根元素 font-size
3. 布局使用 Flex 实现弹性自适应，关键区域响应式调整
适用场景：
- H5 活动页面
- 移动端官网
- 移动端 Web App
- 微信公众号页面
- 需要适配各种手机屏幕的页面
技术要点：
- rem 单位：相对于根元素 font-size 的单位
- JS 动态设置 html font-size，通常按屏幕宽度 / 设计稿宽度 * 基准字体
- 配合 viewport meta 标签设置视口
- Flex 布局实现灵活的页面结构
- Media Query 处理横竖屏和极端尺寸
- 设计稿通常是 750px（iPhone 6/7/8 物理像素）
可迁移性：
- 可迁移到任何移动端 H5 页面
- rem 方案是移动端适配的经典方案
- 可与 vw/vh、flexible.js 等方案结合
