Question

I have something like this at the click fu

Answer 1

That is not possible.

I ran the following snippet in my browser console:

var e = document.getElementById('answers');
(e.webkitRequestFullScreen || e.mozRequestFullScreen).apply(e);

Chrome told me:

Failed to execute 'requestFullScreen' on 'Element': API can only be initiated by a user gesture.

Firefox told me:

Request for full-screen was denied because Element.mozRequestFullScreen() was not called from inside a short running user-generated event handler.

That is a restriction put in place to prevent abuse, similar to that on window.open (see this or this question for example).
