Can Website Buttons Control Browser Zoom?

Browser Zoom Control via Buttons

Question:

Can buttons be created on a website to dynamically adjust the browser's zoom level?

Answer:

Yes, it is possible to modify browser zoom levels using buttons in Internet Explorer and Chrome. However, this feature is not available in Firefox.

Implementation:

The following code snippet demonstrates how to implement browser zoom control buttons using JavaScript:

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

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

In this example, a button is created by wrapping an image with an onclick attribute that calls the toggleZoomScreen() function. When the button is clicked, the function applies a zoom level of 80% to the body element of the web page, effectively changing the browser's zoom.
