zooming asp.net panel/div using javascript

You asked this question some one month back: provide Zoom in and Zoom out for asp.net panel contol[^]

Based on what you ask, there is nothing specific like zooming a panel.
You can zoom images and Microsoft has an AJAX control for the same: Ajaxtoolkit: Seadragon control with default properties[^]

function zoomIn()
{
    //alert("in");
    var Page = document.getElementById('body');
    var zoom = parseInt(Page.style.zoom) + 50 +'%'
    Page.style.zoom = zoom;
    return false;
}
function zoomOut()
{
    //alert("out");
    var Page = document.getElementById('body');
    var zoom = parseInt(Page.style.zoom) - 50 +'%'
    Page.style.zoom = zoom;
    return false;
}
