Growl uses WebKit styles to control the appearance of notifications displayed by the application. A .growlstyle file stores one of these saved styles.
The file belongs to Growl's themes and display-style system rather than being a general-purpose WebKit document. It is intended to be imported into Growl and used as a notification style.
The format is associated with the Mac OS X and macOS versions of Growl.
A .growlstyle file is intended to be used by Growl, not opened as a standalone document. On Mac OS X or macOS, it can probably be imported through Growl's style or display preferences and selected as the notification style.
There is no standard conversion format for a .growlstyle file. Use it directly in Growl; converting it to another format would not preserve its Growl-specific notification style.
