How to automatically present a video in Full Screen mode

Hi Igee, thanks a lot for getting back to me,

this is one of the scripts i tried:

function goFullscreen(id) {
var element = document.getElementById(id);

if (element.mozRequestFullScreen) {
element.mozRequestFullScreen();
} else if (element.webkitRequestFullScreen) {
element.webkitRequestFullScreen();
}
}

<img class="video_player" src="image.jpg" id="player"></img>
<button onclick="goFullscreen('player'); return false">Fullscreen</button>

This the screen I have entered it into, but i was not sure where to enter it or whether to delete what was already there...

hey @Luke_may001 - You get the error cause you are trying to use a "<" however, in order to use a "<" tag you would need to use jQuery. I see you are using something along the lines of <img class, (not able to see more of the code due to the Alert pop-up so I am unsure what is that for?

Are you using an iFrame to embed your video into Qualtrics or have you uploaded the video from your local machine?

Hi Igee, thanks for getting back to me again! I uploaded the video directly from my drive so not iframe, do you have any script for that situation?
