How I implement Jitsi meet Full screen?

const domain = ‘meet.jit.si’;
const options = {
roomName: ‘JitsiMeetAPIExample’,
width: 700,
height: 700,
parentNode: document.querySelector(’#meet’),
lang: ‘de’
};
const api = new JitsiMeetExternalAPI(domain, options);

What is the new Height and Width for the full screen …?

If you omit the width and height, it should default to 100% of the containing element. So to get full screen, just make sure the parent div covers the full screen and has no margins.

Here’s an example: JSFiddle
