 +===== GTK3 Theme testing and debugging =====
 +
 +For testing, you can make modifications in the override file located at **~/.config/gtk-3.0/gtk.css**. If the directory path doesn't exist, then you will have to create it.
 +
 +    mkdir -p  ~/.config/gtk-3.0
 +
 +To see your modifications applied, you can reset the xfce4-panel process by typing the following command into a terminal:
 +
 +    xfce4-panel -r
 +
 +For debugging, you can use the [[https://wiki.gnome.org/action/show/Projects/GTK/Inspector|GtkInspector tool from GNOME]]. To inspect the XFCE panelbar and its plugins, you can perform the following:
 +
 +Kill the current xfce panel process:
 +
 +    pkill xfce4-panel
 +
 +Start the panel process with GtkInspector debugging enabled:
 +
 +    GTK_DEBUG=interactive xfce4-panel
