Vue --- 引入reset.css和border.css文件

一、分别有reset.css和border.css两个文件，我是放在了初始项目的assets文件夹下的；
引用方法如下
只需要在main.js里写入如下代码即可，当然路径按自己的实际情况来写

import './assets/reset.css'
import './assets/border.css'

二、reset.css，初始化整体样式，去除某些标签的默认样式，比如

的小黑点；
因为每个人用的初始化样式都有所区别，但都大同小异，所以这里我只放我目前在用的代码，大家也可以自行搜索其他开发者发布的版本

三、border.css，解决移动端1px边框的问题；
某些高分辨率的手机会把你写好的1像素的边框给显示成2像素，所以需要使用该css来控制
