What is an iframe and what is it used for?

The <iframe> (Inline Frame) element creates an embedded (floating) frame that can load content from another source (usually another URL) into the current HTML document.

It is used for:

• Embedding content from other sites: maps (Google Maps), videos (YouTube), social media widgets, third-party forms.
• Isolating content: the iframe content operates in a separate environment, isolated from the parent page, which enhances security.
• Creating independent blocks: allows developing and managing separate parts of a web page independently.

Example of usage:

<iframe src="https://www.example.com" width="600" height="400">
  Your browser does not support iframe.
</iframe>
