Good to know, as i was not aware there was a yellow - upper_third or cyan - middle_centre zones available… just the magneta - lower_third for compliments.

top_bar and bottom_bar are light gray
top_left and bottom_left are red
top_center and bottom_center are blue
top_right and bottom_right are green
upper_third is yellow
middle_center is cyan
lower_third is magenta

All these regions will resize as needed.

how is the region of screen ?

For a visual of the regions

              {
			module: 'clock',
			position: 'top_left'
		},
              {        module: 'network-scanner',
                       position: 'top_left'
                      config: { 
                                     options
                     }
               },

This will load the clock first then below it the network scanner… if you want them reversed then you put the network scanner first…
