1. An iframe or inline frame is an HTML element used to embed another HTML document within the current document.
2. To create an iframe, HTML provides the <iframe>...</iframe> tag.
3. It is a container tag.
4. It is an inline-level element.
5. To mention the path of the document, we have to use the src attribute.
6. We can also set the height and width of an iframe using height and width attributes.
7. Syntax: <iframe src='path-of-the-document' height='value' width='value'></iframe>
8. It is not recommended to use multiple iframes on a webpage because it slows down the webpage, creating a negative impact on the website's performance and user experience.
