allowfullscreen

React

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.

In React, the allowfullscreen attribute can be added to an iframe element in the same way as it would be added in an HTML document. For example, consider the following code:

import React from 'react'; function MyComponent() { return ( <iframe src="https://www.youtube.com/embed/dQw4w9WgXcQ" allowfullscreen /> ); }

In this example, the iframe element is rendered with the allowfullscreen attribute set to true, which allows the embedded YouTube video to be viewed in fullscreen mode.

Additionally, the allowfullscreen attribute can be used with the React.createElement() method to create an iframe element in a more low-level manner. For example:

import React from 'react'; function MyComponent() { return React.createElement('iframe', { src: "https://www.youtube.com/embed/dQw4w9WgXcQ", allowfullscreen: true }); }

In this example, the allowfullscreen attribute is added to the iframe element by passing it as a property to the React.createElement() method.

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.
