Frequently Asked Questions
What is an iframe embed code?
An iframe (inline frame) is an HTML element that embeds another web page inside your page. YouTube, Vimeo, and Google Maps all publish embeddable players that you place on your site with an iframe tag. This generator builds that tag for you with the correct attributes.
Why is my embedded page blank in the preview?
Some sites send X-Frame-Options or Content-Security-Policy frame-ancestors headers that forbid embedding outside their own players. YouTube videos, Vimeo players, and Google Maps embeds are allowed, but plain Google search pages or most regular websites are not. Use the provider embed URL for those cases.
What does the sandbox attribute do?
The sandbox attribute restricts what embedded content can do - running scripts, submitting forms, opening popups, or accessing your page origin. Each permission is opt-in. Be careful combining allow-scripts with allow-same-origin on untrusted content, because that combination lets the frame remove its own restrictions.
How does the responsive wrapper work?
The generator wraps the iframe in a div that reserves vertical space with a padding-bottom percentage equal to your aspect ratio, then positions the iframe absolutely on top at 100% width and height. The frame therefore scales with the container width while keeping its shape on every screen size.
