/* CSS Theming/Custom CSS :: fancy.css
|
|
*
|
|
* GTK+ uses CSS for theming. If required, applications can
|
|
* install their own custom CSS style provider to achieve
|
|
* special effects.
|
|
*
|
|
* Doing this has the downside that your application will no
|
|
* longer react to the users theme preferences, so this should
|
|
* be used sparingly.
