You can display where ever you like. You change the "left" and "top" values in the opening "div" tag above to whatever values you need. 
a) "top" is the vertical distance of the top left corner of the display starting at zero. The higher the number the lower down the page.
b) "left" is the horizontal distance of the top left corner of the display starting at zero. The higher the number the further across the page.
c) You can change also the color of the display and the background.
