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.</P> Fri, 07 Dec 2018 15:42:03 GMT https://community.hubspot.com/t5/APIs-Integrations/CRM-Extensions-Action-Iframe-Style/m-p/226041#M4937 cbarley 2018-12-07T15:42:03Z
