luffy前台准备

前台

vue环境

1.傻瓜式安装node: 
官网下载：https://nodejs.org/zh-cn/

2.安装cnpm: 
>: npm install -g cnpm --registry=https://registry.npm.taobao.org

3.安装vue最新脚手架: 
>: cnpm install -g @vue/cli

注：如果2、3步报错，清除缓存后重新走2、3步
>: npm cache clean --force

创建项目

"""
前提：在目标目录新建luffy文件夹
>: cd 建立的luffy文件夹
>: vue create luffycity

问题：浏览器缩放时，轮播图显示不全，滚动水平滚动条，发现图片缺失

解决：隐藏水平滚动条，页面都只提供垂直滚动条的需求

global.css

/* 水平超出部分默认隐藏 */
#app {
    overflow: hidden;
}
