Phoenix: how to avoid including Bootstrap/HTML5 boilerplate in generated CSS production file

Question

When I deployed my Phoenix app in production for the first time I saw that my CSS were broken due to the app.cssgenerated file include not wanted CSS such as Bootstrap and HTML5 boilerplate. I imagine they are included by brunch when compiling in production mode. How to avoid it?

You can just delete everything in web/static/css/app.css file. And then recompile your project
