Adding custom CSS

In config.yaml you can add a extra_css_file entry pointing to a CSS file which will be included on every page:

config.yaml

---
course_title: My course
extra_css_file: extra.css

Then in the CSS file you can put CSS you like:

extra.css

body {
   font-size: 2rem;
}

nbpretty will automatically add the CSS to every generated HTML page after all other CSS files:

<style>@import 'extra.css'</style>
