I'm using Gantry 5 with CALLISTO Template.
The home page is configured like this :
- Blog 2 columns
In a screen, I could have 2 columns : OK
If I see the home page with a smartphone, with a responsive template, I have to see all content in ONE column. In fact I have 2 columns.
You could see :
With older template using Gantry 4, it was responsive 1 column with smartphone.
Thank you for your help !
