webpack打包多页demo

配置了scss

使用scss来写css提高效率

配置了postcss

自动补全css浏览器前缀和rem自动转换
无需再写css3各浏览器的前缀，也无需用rem这种难以心算的单位来布局了，设计稿多少就敲多少px。

内置了jquery

直接可以使用“&”无需引入script文件或者用require import来引入。

可以放心的写多页应用

可以像图片中目录一样嵌套，
建议每一个文件中只包含一个*.html，一个*.scss，一个*.ts，这样结构是最清晰的表现形式，可以在一个文件中嵌套另一个文件保存同样的内容，程序会递归所有的文件夹。

❗ 不建议一个文件中包含多个*.html.
