HTML – Iframes

HTML (Hypertext Markup Language) Iframes, abbreviated for inline frames, stand as potent components enabling web developers to seamlessly integrate external content within a webpage’s confines. They furnish a portal to another webpage, facilitating the exhibition of content from diverse origins sans redirection. Grasping the adept utilization of Iframes can substantially augment a website’s functionality and the end-user’s experience.

What Comprises Iframes?

This procedural sequence facilitates developers in seamlessly incorporating content from external origins into their own webpages. Each Iframe functions as an autonomous browsing context, maintaining its distinct session storage and cookies, thereby ensuring segregation from the parent document.
