How to set homepage at full width

Hello.
I’ve got a problem with the homepage, because i cannot put it at full width.
I’m using a custom page i called home, within it I’m using bootstrap code to create content. Whatever I do, all the content remains centered with 2 columns on the left and right side. I’ve tried to inspect the page in order to find out which parameters are forcing the page but without any result. Could anyone explain me where I’m doing wrong?
I’ve already put the page at full width in the homepage editor right section, but nothing changes.
