Simple Calendar exposes several CSS variables that can be used to change its appearance. These variables are used by the built-in themes to control their appearance but can be overwritten to match a third party modules overall theme.
These variables are added to the .simple-calendar.{theme} classes. Example for the dark theme would be .simple-calendar.dark class will have the CSS variables. These classes are added by default to each Foundry VTT application to ensure all dialogs look correct.
