This css sets the background image to not repeat, the size of the image to cover the space (100% width or 100% height with the other being proportionate) and it sets the position to be the horizontal and vertical center of the area. You can adjust any of these if you do not want it to cover the full space or you do not want it to be positioned in the center.
