This is almost all bare html: if you want to make a change, modify the relevant HTML file directly.
The exception is the list of upcoming dances, which is in JSON at the beginning of dances.js. Don't delete old dances: they're only shown when someone chooses to display past dances, and it's nice to preserve the history.
This is deployed with GitHub Pages, and changes go live when you push them.
