How use <iframe> allow attribute?

@cali_green 

The allow attribute in the <iframe> element is used to specify a set of restrictions for the content within the embedded iframe.

Here is an example of how to use the allow attribute in an <iframe> element:

1

<iframe src="https://www.example.com" allow="autoplay; encrypted-media"></iframe>

In the example above, the allow attribute is set to allow autoplay and encrypted media within the iframe. You can specify multiple restrictions by separating them with a semicolon.

Some common values for the allow attribute include:

• autoplay: Allows automatic playback of audio or video content within the iframe.
• encrypted-media: Allows playback of encrypted media within the iframe.
• fullscreen: Allows the iframe to request full screen display.
• geolocation: Allows access to the user's geographical location.
• microphone: Allows access to the user's microphone.
• camera: Allows access to the user's camera.

Make sure to carefully consider which restrictions to allow based on the content of the embedded iframe and the security and privacy implications.
