GTK+ with css examples

[Kylewojo]

can someone type up a simple example for styling a GTK+ widget with css? I cannot for the life of me figure it out\[code\]#include <gtk/gtk.h>int main(int argc,char *argv[]){ gtk_init(&argc,&argv); GtkWidget *window; GtkWidget *button; GtkCssProvider *cssProvider; gtk_css_provider_load_from_path(cssProvider,"./gtkExample2.css",NULL); window = gtk_window_new(GTK_WINDOW_TOPLEVEL); button = gtk_button_new_with_label("GTK Button"); gtk_style_context_add_provider(gtk_widget_get_style_context(window),cssProvider,GTK_STYLE_PROVIDER_PRIORITY_USER); g_signal_connect_swapped(window,"delete-event",G_CALLBACK(gtk_widget_destroy),window); gtk_container_set_border_width(GTK_CONTAINER(window),20); gtk_container_add(GTK_CONTAINER(window),button); gtk_widget_show(window); gtk_widget_show(button); gtk_main(); return 1;}\[/code\]
