Would be nice to make a website that automatically resizes depending on user-screen size. I would love to see this option added to website x5

When I open up my a website on a smaller screen with smaller resolution example a laptop 13" the website background doesn't display as it would on my 22" screen for example www.shoetube22.com I made that website with my 22" screen computer 1680x1050 if you view it full screen in any other screen it won't resize automatically to fit your screen size. I would love to have the option of where the website would be able to resize any screen size depending on it's size.
