How do you resize a browser window so that the inner width is a specific value

Question

If you are just here to tell me on why resizing a window is a bad idea, obnoxious, and the web-equivalent of nails on a chalk board, then please go away. I am looking for a

The post is quite old, but here is a concrete implementation for future readers :

var resizeViewPort = function(width, height) {
    if (window.outerWidth) {
        window.resizeTo(
            width + (window.outerWidth - window.innerWidth),
            height + (window.outerHeight - window.innerHeight)
        );
    } else {
        window.resizeTo(500, 500);
        window.resizeTo(
            width + (500 - document.body.offsetWidth),
            height + (500 - document.body.offsetHeight)
        );
    }
};

And if you want to take the scrollbars into account :

var resizeViewPort = function(width, height) {
    var tmp = document.documentElement.style.overflow;
    document.documentElement.style.overflow = "scroll";

    if (window.outerWidth) {
        window.resizeTo(
            width + (window.outerWidth - document.documentElement.clientWidth),
            height + (window.outerHeight - document.documentElement.clientHeight)
        );
    } else {
        window.resizeTo(500, 500);
        window.resizeTo(
            width + (500 - document.documentElement.clientWidth),
            height + (500 - document.documentElement.clientHeight)
        );
    }

    document.documentElement.style.overflow = tmp;
};

Have fun...
