A rip-off of Solarized css but with the color palette of org-roam-server's darkmode, which I like a lot better. Hosted here so I can share my notes easier with easier navigation than a pdf.
Add these lines and run org-export-dispatch
#+INFOJS_OPT: view:showall toc:t ltoc:t mouse:underline buttons:0 path:http://ajjacobs.github.io/darkmode-css/src/js/org-info.min.js
#+HTML_HEAD: <link rel="stylesheet" type="text/css" href="https://ajjacobs.github.io/darkmode-css/src/css/darkmode.css" />
If you prefer, you could also copy these into a local file, e.g. darkmode.setup, and use
#+INCLUDE: path/to/darkmode.setup
