一、Vue移动端项目前准备

1.更改 index.html 的属性

index.html在public目录下

<meta name="viewport" content="width=device-width,initial-scale=1.0,
    minimum-scale=1.0,maximum-scale=1.0,user-scalable=no">

2.解决各个显示终端样式的一致性

reset.css

@charset "utf-8";

    background-color: #fff;
    color: #000;
    font-size: 12px

4.解决移动端300毫秒点击延迟的问题

引入 fastclick 插件

备注：这里适用于 js 项目下，在 typescript 这样会报错，不知道为啥？

（1）安装 fastclick 插件

cnpm install fastclick -S

（2）在 mian.js 中引入

import FastClick from 'fastclick'
FastClick.attach(document.body);

到此，项目先期准备完毕！
