An iFrame (Inline Frame) is an HTML element used to embed another HTML document within the current page. It allows you to display content from external sources, such as videos, maps, or other websites, directly within your page. This can be especially useful for integrating third-party services like YouTube videos or Google Maps without having to redirect users to another page.
The iFrame tag supports attributes like "src" for the URL of the content to be embedded, "width" and "height" for defining its size, and "frameborder" for adjusting the border visibility. It also offers flexibility to adjust the embedded content’s responsiveness, which makes it adaptable to different screen sizes.
