How do you enable allowfullscreen in an iframe HTML tag?

Answers:

• To enable fullscreen capability in an iframe, you need to include the allowfullscreen attribute in the <iframe> tag. This attribute allows the content within the iframe to be displayed in fullscreen mode. Additionally, you may also want to include the webkitallowfullscreen, mozallowfullscreen, and msallowfullscreen attributes for better compatibility across different browsers. Here's an example of how to do this:

  <iframe src="your-video-source-url" 
          width="560" 
          height="315" 
          frameborder="0" 
          allow="autoplay; encrypted-media" 
          allowfullscreen 
          webkitallowfullscreen 
          mozallowfullscreen 
          msallowfullscreen>
  </iframe>
  

  In this example:

  • src: This should be the URL of the page or video you want to embed.
  • width and height: These define the dimensions of the iframe.
  • frameborder: This attribute can be used to specify whether to show a border around the iframe.
  • allow: This attribute specifies the permissions for the iframe's content (e.g., enabling autoplay or encrypted media).
  • The allowfullscreen, webkitallowfullscreen, mozallowfullscreen, and msallowfullscreen attributes are included to ensure support across multiple browsers.

  Make sure to replace "your-video-source-url" with the actual URL you want to embed.
