I am developing a web app and all ui element will be not in a correct order if user zoom in / zoom out . So, are there any way to prevent it? I have think of some way to do it but is it possible ?

1) Get the screen resolution of the user. When the window size is change (either width or height), return the window width/height to screen width /height.

2) bind the mouse scroll event or keyboard event to nothing. (Refer to above demo code) , but what if the user click on the browser and select zoom in ?

Thanks

    var zoomlevel=1;

    $("body").dblclick(function(ev) {
        zoomlevel = zoomlevel == 1 ? 2 : 1;



        $(this).css({
            "-moz-transform":"scale("+zoomlevel+")",
            "-webkit-transform":"scale("+zoomlevel+")",
            "-o-transform":"scale("+zoomlevel+")",
            "-ms-transform":"scale("+zoomlevel+")"
        });
