cssify | Simple middleware for Browserify to add css styles | Plugin library

I build a simple chrome extension and would like to publish it.

The problem is, I don't know how to proceed with some css files.

I used browserify and yarn to install bulma.

in my main.js I got the following line:

import Styles from './styles.css'

and the first line of styles.css looks like this:

@import '../node_modules/bulma/css/bulma.css';

Here's my build command from package.json
