Can I use both allowfullscreen and allow='fullscreen' together?

Answers:

• Yes, you can use both the allowfullscreen attribute and the allow='fullscreen' attribute together in HTML for an iframe element. However, it’s important to understand their differences:

  1. allowfullscreen: This is a boolean attribute that is a part of the iframe element. If present, it indicates that the iframe can be put into full-screen mode. It does not require a value; simply including it as <iframe allowfullscreen></iframe> allows full-screen usage.

  2. allow='fullscreen': This is a part of the allow attribute, which provides more granular control over what features the iframe can use. Setting allow='fullscreen' explicitly allows the iframe to request full-screen capabilities, similar to allowfullscreen.

  Using both together is valid and can be done as follows:

  <iframe src="your_video_source" allowfullscreen allow="fullscreen"></iframe>
  

  Both attributes serve the same purpose, but using them together can be considered a redundancy. It's generally sufficient to use one of them, but if you prefer to be explicit or support older browsers while also adhering to modern standards, using both will not cause any issues.
