## Includes

    #include <gtk/gtk.h>

## Description

GtkStyleProperties provides the storage for style information that is used by GtkStyleContext and other GtkStyleProvider implementations.

Before style properties can be stored in GtkStyleProperties, they must be registered with `gtk_style_properties_register_property()`.

Unless you are writing a GtkStyleProvider implementation, you are unlikely to use this API directly, as `gtk_style_context_get()` and its variants are the preferred way to access styling information from widget implementations and theming engine implementations should use the APIs provided by GtkThemingEngine instead.

GtkStyleProperties has been deprecated in GTK 3.16. The CSS machinery does not use it anymore and all users of this object have been deprecated.

## Functions
