allowfullscreen
an HTML attribute for the iframe tag

Is allowfullscreen required for embedded videos to go fullscreen?

Answers:

  • Yes, the allowfullscreen attribute is required for embedded videos to enable fullscreen functionality in most browsers. When you embed a video using HTML, such as with an <iframe> element, including the allowfullscreen attribute allows users to access the fullscreen option.

    Here's an example of how you might include it in an iframe:

    <iframe src="https://www.example.com/video" 
            width="560" 
            height="315" 
            allowfullscreen>
    </iframe>
    

    Without allowfullscreen, the fullscreen option may not be available to users when they try to play the video. It's considered a good practice to include this attribute if you want to provide a fullscreen viewing experience.
