Is there any way to put custom CSS inside the Lightbox that opens when the user clicks on an Action of type IFRAME?? I want to get rid of this lightbox margins to take advantage of the limited space (In other words, make the Iframe have 100% width and height from its parent).
Hi @Marco_Artavia, unfortunately not. That padding is set from a React Component we use on the front end for every HubSpot account. All iFrames in a CRM Extension popout have a padding of 40px on the sides and 24px on the top and cannot be altered.
