@coorpacademy/css-wrapper-webpack-plugin

Disclaimer: you should use this plugin with minified css only.

What it does

Providing your minified styles.css is:

.plop {opacity: .5;}.plup {height: 12px;}

the final css will be wrapped with your container

#app .plop {opacity: .5;}#app .plup {height: 12px;}

Usage

require the plugin

const WebpackCSSWrapperPlugin = require('@coorpacademy/webpack-css-wrapper');

then within your webpack plugins:

plugins: [
  new ExtractTextWebpackPlugin('styles.css'),
  new WebpackCSSWrapperPlugin('styles.css', '#app')
]
