First, create your own `_custom.scss` and use it to override the [built-in custom variables]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/options/). Then, use your main Sass file to import your custom variables, followed by Bootstrap: {% highlight scss %} @import "custom"; @import "~bootstrap/scss/bootstrap"; {% endhighlight %} For Bootstrap to compile, make sure you install and use the required loaders: [sass-loader](https://github.com/webpack-contrib/sass-loader), [postcss-loader](https://github.com/postcss/postcss-loader) with [Autoprefixer](https://github.com/postcss/autoprefixer#webpack). With minimal setup, your webpack config should include this rule or similar: {% highlight js %} ... { test: /\.(scss)$/, use: [{ loader: 'style-loader', // inject CSS to page }, { loader: 'css-loader', // translates CSS into CommonJS modules }, { loader: 'postcss-loader', // Run postcss actions options: { plugins: function () { // postcss plugins, can be exported to postcss.config.js return [ require('autoprefixer') ]; } } }, { loader: 'sass-loader' // compiles Sass to CSS }] }, ... {% endhighlight %} ### Importing Compiled CSS Alternatively, you may use Bootstrap's ready-to-use CSS by simply adding this line to your project's entry point: {% highlight js %} import 'bootstrap/dist/css/bootstrap.min.css'; {% endhighlight %} In this case you may use your existing rule for `css` without any special modifications to webpack config, except you don't need `sass-loader` just [style-loader](https://github.com/webpack-contrib/style-loader) and [css-loader](https://github.com/webpack-contrib/css-loader). {% highlight js %} ... module: { rules: [ { test: /\.css$/, use: ['style-loader', 'css-loader'] } ] } ... {% endhighlight %}
