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.
