Change #background color to #202020 while using en_Night.css

During Fullscreen display the image might not cover the entire screen, hence the background is exposed and is #ffffff even if the 'Night' Style is used.  This modification will change the background to #202020 while using the 'Night' Style or en_Night.css.
