zoom css/javascript

The Firefox & Chrome (Webkit) equivalents to the IE-specific zoom property are, respectively, -moz-transform and -webkit-transform.

A sample code would be:

.zoomed-element {
    zoom: 1.5;
    -moz-transform: scale(1.5);
    -webkit-transform: scale(1.5);
}

You'd have to be a bit more careful with Javascript (test for existence first), but here's how you'd manipulate them:

el.style.zoom = 1.5;
el.style.MozTransform = 'scale(1.5)';
el.style.WebkitTransform = 'scale(1.5)';

It is a property of style, but it's not supported by all browsers. It's a non-standard Microsoft extension of CSS that Internet Explorer implements. It is accessed like this:

div.style.zoom

You might want to try a lightweight jQuery plugin called Zoomoz. It uses CSS3 transform properties (translate, rotate, scale). Check out the "Zooming the jQuery way section. Hope it helps.

$(document).ready(function() {
    $("#element").zoomTarget();
});
