This setting only works if you are on the same domain! 

Same domain: You can modify things with the shortcode
Remote domain: You need the external workaround to modify the iframe content.

Hi Michael

Yes I own both websites and I am using the external workaround. Is there any setting I can use to hide the background of the embedded website.

Otherwise, I would really appreciate you giving me some help with the CSS code that I need to add to the embedded website that would hide the background when embedded into the host website.

Thanks for you valuable support

Neil

Hi, you can simply set the background to transparent or none. This is simple css. You can include this into the page in several ways. 

The quickest way is to add this change in the administation: advanced iframe -> Modify the iframe -> there you can change styles. This are saved to the ai_external.js which are then use by your iframe.

Best, Michael
