I am building my site using panels , mini panels on every page. In addition, I am using the panels everywhere modules. The theme I am using is: "Adaptivetheme".
I every page I built (using page manager and panels), I chose a panels layout of "AT responsive panels" 3 or 2 columns, depends on the page.
can I change the ratio of the columns of the layouts, so it will be, for examples 20/55/25, instead of the default 25/50/25?
