HTML Iframe

    Using the <iframe> element we can add a new HTML document in the existing one.  The <iframe> element create a rectangular region with its own borders and scrollbar that can show a separate web page.

    <iframe> syntax 

    <iframe src="URL"> </iframe>

    Example 

    <!DOCTYPE html>
<html>

   <head>
      <title>HTML Iframes</title>
   </head>
	
   <body>      
   <iframe src ="https://www.techgeekbuzz.com/">         
  
    <!-- this message will be shown if the browser does not support iframe -->    
     Browser does not support <iframe>
  </iframe>
   </body>
	
</html>
