HTML iFrame
An <iframe> embeds another web page or document inside your page. Think of it as a small window inside your page that can show content from another location. The src attribute tells the iframe what to load. width and height control its starting size. Common uses include maps, videos, documents, and trusted external tools. Because an iframe loads outside content, security and privacy settings matter. The sandbox attribute can restrict what the embedded page is allowed to do.
