Hi Guys

I did my web site in high resolution, all pages are 1920 x 3000 (the hight is varibale and depend of the qty of the information), but always the same width 1920, in my pc with HD monitors the web site looks really nice, but in others pc with lower resolution (non HD) the web site looks too big, so how we can do to allow that the web site auto - adjust according to the resolution of the monitor and looks great regardless the monitor resolution?
