Iframe tag in HTML

The iframe tag is used to display another webpage in the current webpage.

The iframe tag

The iframe tag has an src attribute which specifies the link of the web page to be displayed in the current webpage. If the webpage is in the current directory just mention its name Otherwise, specify its exact path. There are also optional attributes like height and width which specifies the height and width taken by the iframe webpage. 
 
    <!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <meta http-equiv="X-UA-Compatible" content="IE=edge">
        <meta name="viewport" content="width=device-width, initial-scale=1.0">
        <title>Document</title>
    </head>
    <body>
    <iframe> src="rapid_coders.html" height="300" width="300"></iframe>
    </body>
    </html>
By default, if we don't specify height and width, it will take approx 300px X 150px. Also, note that not every webpage allows itself to be displayed as an iframe. So, don't be disappointed when you see something like this.
Your code is absolutely fine.
