The allowfullscreen attribute is used with the iframe element in HTML to allow a video or other embedded content to be viewed in fullscreen mode. This attribute is typically used with a value of true, which indicates that the embedded content should be allowed to be viewed in fullscreen mode.

When using the allowfullscreen attribute with Vimeo, it's important to ensure that the Vimeo player is set up to allow fullscreen mode. This can be done by setting the allowfullscreen parameter to true when generating the Vimeo player code.

For example, consider the following Vimeo player code:

<iframe src="https://player.vimeo.com/video/76979871?title=0&byline=0&portrait=0&badge=0&allowfullscreen=true" frameborder="0" allow="autoplay; fullscreen" allowfullscreen></iframe>

In this example, the allowfullscreen parameter is set to true, which enables the fullscreen mode for the Vimeo player. Additionally, the allowfullscreen attribute is added to the iframe element, which allows the player to be viewed in fullscreen mode when the user clicks on the fullscreen button in the player controls.

Alternatively, the allowfullscreen attribute can be added directly to the iframe element when generating the Vimeo player code. For example:

<iframe src="https://player.vimeo.com/video/76979871?title=0&byline=0&portrait=0&badge=0" frameborder="0" allow="autoplay; fullscreen" allowfullscreen></iframe>

In this example, the allowfullscreen attribute is added directly to the iframe element, which allows the Vimeo player to be viewed in fullscreen mode when the user clicks on the fullscreen button in the player controls.

It's worth noting that the allowfullscreen attribute is not supported by all browsers, so it's important to test your code in a variety of browsers to ensure that it works as expected.
