css doesn't work when deploy rails application heroku.

my application.css.scss has:

@import 'normalize';  @import 'skeleton';  @import 'animate.min';  @import 'froala_editor.min.css';  @import 'froala_style.min.css';  @import 'font-awesome';    @import 'plugins/char_counter.min.css';  @import 'plugins/code_view.min.css';  @import 'plugins/colors.min.css';  @import 'plugins/emoticons.min.css';  @import 'plugins/file.min.css';  @import 'plugins/fullscreen.min.css';  @import 'plugins/image_manager.min.css';  @import 'plugins/image.min.css';  @import 'plugins/line_breaker.min.css';  @import 'plugins/table.min.css';  @import 'plugins/video.min.css';

i tried using gems rails_12factor, rails_serve_static_assets , :

 config.serve_static_files = true 

also:

rails_env=production bundle exec rake assets:precompile

the answer here:

https://stackoverflow.com/questions/15354539/heroku-does-not-compile-files-under-assets-pipelines-in-rails-4

only changed:

 config.assets.compile = false 

by:

config.assets.compile = true
