I have followed the instructions in the readme file.

This is my code:

= inline_css 'style', 'highlighting.css'

Alternative approach works fine but I want to inline that CSS, not just put a link outside the head:

= stylesheet_link_tag 'highlighting.css'

Is your gem compatible with latest version of middleman?

@girlonrails I had this problem too. ended up just skipping the gem.

My example uses slim but should work in other templating languages. I am rendering "critical.css" in the header.

css:
   #{sitemap.resources.find{|r| r.source_file.match('critical.css')}.render}
