GTK_STYLE_PROVIDER_PRIORITY_FALLBACK

#define GTK_STYLE_PROVIDER_PRIORITY_FALLBACK      1

The priority used for default style information that is used in the absence of themes.

Note that this is not very useful for providing default styling for custom style classes - themes are likely to override styling provided at this priority with catch-all * {...} rules.


GTK_STYLE_PROVIDER_PRIORITY_THEME

#define GTK_STYLE_PROVIDER_PRIORITY_THEME     200

The priority used for style information provided by themes.


GTK_STYLE_PROVIDER_PRIORITY_SETTINGS

#define GTK_STYLE_PROVIDER_PRIORITY_SETTINGS    400

The priority used for style information provided via GtkSettings.

This priority is higher than GTK_STYLE_PROVIDER_PRIORITY_THEME to let settings override themes.


GTK_STYLE_PROVIDER_PRIORITY_APPLICATION

#define GTK_STYLE_PROVIDER_PRIORITY_APPLICATION 600

A priority that can be used when adding a GtkStyleProvider for application-specific style information.


GTK_STYLE_PROVIDER_PRIORITY_USER

#define GTK_STYLE_PROVIDER_PRIORITY_USER        800

The priority used for the style information from ~/.gtk-3.0.css.

You should not use priorities higher than this, to give the user the last word.
