The <iframe> element is an HTML tag used to embed or display another HTML document within the current document. The term “iframe” stands for “inline frame.” It creates a rectangular region on a web page that acts as a container for displaying content from a different source.
The <iframe> element is often used to include external content such as a webpage, video, map, or advertisement within a parent HTML document. It allows you to seamlessly integrate content from different sources into your own webpage.
When using the <iframe> element, you specify the source of the content using the `src` attribute, which holds the URL of the document to be displayed within the frame. The width and height attributes determine the dimensions of the frame, defining how much space it occupies on the page.
Furthermore, the <iframe> element supports several attributes that control the behavior and appearance of the embedded frame. These attributes include `frameborder` to specify whether a border should be displayed, `scrolling` to determine if scrollbars should be included, and `name` to provide a unique identifier for the frame for targeting or linking purposes.
The <iframe> element is a versatile tool for integrating external content and enhancing the functionality of web pages. It enables developers to present dynamic and interactive elements seamlessly within their websites while maintaining a structured and organized layout.
