CSS not loading instantly in webpack project

Question

Here is the image which shows the first time of loading

After microseconds, everything is fine such as design, javascript, images, etc...

Here is my webpack.config.js:

const path = require('path');
const webpack = require('webpack');
var HtmlWebpackPlugin = require('html-webpack-plugin');
const MiniCssExtractPlugin = require("mini-css-extract-plugin");

module.exports = {
    mode: 'development',

    entry: './src/index.js',
    output: {
        filename: 'bundle.js',
        path: path.resolve(__dirname, 'dist')
    },

    module: {
        rules: [
            {
                test: /\.js$/,
                exclude: /node_modules/,
                use: {
                    loader: "babel-loader"
                }
            },
            {
                test: /\.html$/,
                use: [
                    {
                        loader: 'html-loader',
                        options: { minimize: true }
                    }
                ]
            },
            {
                test: /\.(scss|css)$/,
                use: [
                    {
                        // Adds CSS to the DOM by injecting a `<style>` tag
                        loader: 'style-loader'
                    },
                    {
                        // Interprets `@import` and `url()` like `import/require()` and will resolve them
                        loader: 'css-loader'
                    },
                    {
                        // Loader for webpack to process CSS with PostCSS
                        loader: 'postcss-loader',
                        options: {
                            plugins: function () {
                                return [
                                    require('autoprefixer')
                                ];
                            }
                        }
                    },
                    {
                        // Loads a SASS/SCSS file and compiles it to CSS
                        loader: 'sass-loader'
                    },
                ]
            },
            {
                test: /\.(png|svg|jpg|gif)$/,
                use: [
                    'file-loader'
                ]
            },
            {
                test: /\.(woff|woff2|eot|ttf|otf)$/,
                use: [
                    'file-loader'
                ]
            },

        ]
    },

    plugins: [
        new HtmlWebpackPlugin({
            template: "./src/index.html",
            filename: "./index.html"
        })
    ]
};

I don't know what I'm missing but I know definitely missing something but not indicating. I tried but didn't get it to work.

I'd really appricitate if could help me resolve this issue.

Thanks

Apparently CSS always loads after JS. Have a look at this issue.

You could also set display: none to your body or main div and change it in the CSS. It would take the same time to load, but you wouldn't see ugly styled content during those microseconds.
