cyber-dojo now supports light and dark themes as well as optional colour-syntax highlighting.
The [theme?] button toggles between the light and dark themes.
The [colour?] button toggles colour-syntax on/off.
The default is the dark-theme with colour-syntax on.
Click [theme?] to switch to light-theme (colour-syntax remains on).
Click [colour?] to switch colour-syntax off (theme remains light).
Click [theme?] to switch to dark-theme (colour-syntax remains off).
Have fun :-)
