attempts to package a multi-page (multi-html file) application through  webpack , but when packaging  css  files through  css-loader  and  style-loader , it is found that  css  imported by entry  js  cannot be packaged into the  head  tag section of  html  file (and try to extract css as a separate file through  extract-text-webpack-plugin ).
webpack configuration file is as follows:
module: {
    rules: [
        //
        {
            test: /\.css$/,
            use:["style-loader","css-loader"]
        },
    ],
}, js entry (chunk) file is as follows ( src/pages/about/index.js ): 
import "./css/index.css"
export default {
    
} Source address:  https://gitee.com/qingyun1029/webpack-for-multiple-page-demo
usage:
-  Clone the project to local 
 git clone git@gitee.com:qingyun1029/webpack-for-multiple-page-demo.git
-  install dependent modules 
 npm install
-  Packaging Code

 after formatting the packaged  html , you will find that there is no  style  tag and style content 
 head  tag.

< H2 > add: < / H2 > suddenly found a strange problem?  html-webpack-plugin ,  css-loader , and  style-loader  are installed in my package.json, but only the first two appear in the console, but  style-loader  does not appear.
