 The `src` attribute specifies the URL of the page you want to embed. The `width` attribute specifies the width of the `iframe`. The `height` attribute specifies the height of the `iframe`. The `allowfullscreen` attribute allows the user to display the `iframe` in full screen mode. It's also a good practice to specify a `title` attribute for the `iframe`, as it's important for accessibility.
 
+The `allow` attribute, on the other hand, lets you define what an iframe can or can't do. This is called an allowlist. In the above example, adding `clipboard-write` to it allows the embedded page to write items to your clipboard. Items in an allowlist can be separated by semicolons or spaces, and both can be used together.

 Note that the video can come from anywhere. It doesn't have to come from video services like YouTube and Vimeo.
 
 Don't forget you can also embed a map, another web page, or direct HTML within the `iframe` element. Here is an example of an embedded map.
