But the bottom-content is dimensionated on the main-body width while i'm need of total width 100%.
As I said, there is a position "bottom" (not "bottom-content"), and if you put 1 module there, it will be 100%.
Should I put bottom-1 with width 100% and bottom-2 with width 50%?
How I Do?
bottom-1 and bottom-2 look like 2 column of a row. So if bottom-1 is 100% then bottom-2 will be jump to the second line.
To change this, just edit css file (custom.css for example) and put the styling you want.
