Assuming you have found my simple Twine-powered political simulation Workers In Progress interesting enough or would like to give Twine a go, I believe you will appreciate having a look at the source code of WIP -- just download it here in one handy .zip file containing the html, twee and twine story files.
I haven't done anything fancy with the game, mind you, but you will get to see how Workers In Progress has been designed, maybe find some useful CSS code and see an example of variables usage. Hopefully, it will be quite helpful for people who haven't twined anything yet.
Reminder: I could really use your support via Patreon and survive long enough to make more indie gaming (and gaming) words and things. Thanks!
