I would like to insert 2 different ads in the ad_header template. So, I'd like to split ad_header into 2 sections. On the left - I would like to insert a responsive adsense ad (adsense responsive code) On the right - I would like to insert static banner link (custom HTML) Is it possible to control the width of these 2 sections? I want this to be responsive so it displays properly on various end user devices (tablet, smart phone, PC/laptop...). How can I do this? Thank you.
