I have created a sub-theme using adp-panels everywhere. I use a single column layout for the default site template. Then I added some mini-panels like header and so. Everything works fine except there are these spaces between the mini-panels. Let's say around 10px between header and primary like menu (plm) , 10px between plm and the mini-panel following it and so on. I really do not want these spaces. I appreciate any help in achieving this.
