Note: The HTML iframe syntax is correct, the https://www.geeksforgeeks.org/community/ website does not allow itself to be embedded in iframes on other domains. This is due to protective headers (X-Frame-Options, CSP) that prevent clickjacking and preserve content security. As a result, the iframe appears broken, even though the code itself is valid. you can use some other website link to check the output

Note: The <frame> tag is not supported in HTML5.
