Is allowfullscreen required for all iframes containing videos?

Answers:

• The allowfullscreen attribute is not required for all iframes containing videos, but it is often necessary if you want to enable fullscreen functionality for that video.

  When you embed a video from platforms like YouTube or Vimeo using an iframe, the allowfullscreen attribute must be included in the iframe tag to allow users to enter fullscreen mode while watching the video. If it is omitted, the fullscreen button may not function or may be disabled.

  Here's an example of how it should look:

  <iframe src="https://www.youtube.com/embed/your-video-id" 
          allowfullscreen></iframe>
  

  In summary, while allowfullscreen is not mandatory for all iframes, it is essential for video iframes if you want to offer users the option to view the video in fullscreen mode.
