r - Tweak formatting of github_document output via css or other method

Question

I would like to tweak some of the formatting of my github_document output. e.g., control font family and size in headers and control justification and line breaks for the Title, Author, and Date in YAML. Can anyone point me toward some basic guide or examples of formatting a github_document from RStudio?

Controlling html_document from YAML is a breeze:

output:
  html_document:
    css: "style.css"

But trying the same with github_document will not work.

output:
  github_document:
    css: "style.css"
