How to fit the website width to the screen width without stretching width on zoomout

HTML & CSS
1

Hello,

I need to fit the website width to the screen width and when I zoom out the browser, I don’t want the website width to stretch on left and right. I am using the Javascript now to assign the website width the value of window.screen.width, but I faced problem with IE7 and IE8 that when I zoom out or zoom in the window, then the value of window.screen.width will change.

I am looking to make something like this website: http://ca.com please try to zoom out and see the website will not stretch on left and right.

Would appreciate your kind hints.

Note: I don’t want to use the Jquery or any library, just pure Javascript or CSS.

Thanks.

Cheers!
