javascript - Changing the browser zoom level

Question

I have need to create 2 buttons on my site that would change the browser zoom level (+) (-). I'm requesting browser zoom and not css zoom because of image size and layout issues.

Well, is this even possible? I've heard conflicting reports.

Answer 1

Possible in IE and chrome although it does not work in firefox:

<script>
   function toggleZoomScreen() {
       document.body.style.zoom = "80%";
   } 
</script>

<img src="example.jpg" alt="example" onclick="toggleZoomScreen()">
