 +===== 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
