`fullscreenchange` occasion
This occasion is fired when the browser enters or exits full display screen mode. You should use this occasion to replace the UI and mirror the present full display screen state (e.g., altering the button icon).
`fullscreenerror` occasion
This occasion is fired if there may be an error through the full display screen request.
Implementing a Full Display screen Button: A Sensible Strategy
Let’s discover the steps concerned in implementing a full display screen button:
Setting up the Basis: The HTML Construction
Step one includes creating the HTML construction on your full display screen button. You should use a easy `<button>` factor:
<button id="fullscreen-button">Fullscreen</button>
<video id="myVideo" src="my-video.mp4" controls></video>

#fullscreen-button {
background-color: #4CAF50; /* Inexperienced */
border: none;
coloration: white;
padding: 10px 20px;
text-align: heart;
text-decoration: none;
show: inline-block;
font-size: 16px;
cursor: pointer;
border-radius: 5px;
}
#fullscreen-button:hover {
background-color: #3e8e41;
}
Bringing It to Life: JavaScript Implementation
That is the place the magic occurs. You’ll use JavaScript to connect an occasion listener to the button and implement the complete display screen performance.
const fullscreenButton = doc.getElementById('fullscreen-button');
const video = doc.getElementById('myVideo');
fullscreenButton.addEventListener('click on', () => {
if (doc.fullscreenElement === null) {
// If not already in fullscreen
video.requestFullscreen()
.catch(err => {
// Deal with errors
console.error(`Error making an attempt to allow fullscreen mode: ${err.message}`);
