You can feed a custom style to any component by passing it in the className prop as per the above example.
Live Reloading
Live reloading is automatically configured. The start script will watch for changes while the build script adds the output CSS file to your static build folder.
Colors
There is also a brand colour configured inside the tailwind.config.js file that you can modify with your brand colours.
Dark Mode
Dark mode is included and can be toggled on or off in the user dropdown nav on the top right corner (click the avatar to open it).
The setting is stored in both the authContext on the client and in the user table of the database so it will persist across user sessions.
If you're new to Tailwind and need more help, the Tailwind documentation provides a comprehensive guide to the principles along with a full reference guide to each utility class helper.
