What is iframe?

Answer 1

An iframe is kind of like a website within your webpage. With an iframe you include the content of another source within your own page.

This can be useful if you want to show ads on a specific place in your site without changing the source URL. On the other hand it gives you the flexibility to change ads without having to change your main site.

Answer 2

An IFrame (Inline Frame) is an HTML document embedded inside another HTML document on a website. The IFrame HTML element is often used to insert content from another source, such as an advertisement, into a Web page.

Answer 3

An inline frame is used to embed another document within the current HTML document.
