Put my new tab as home page


I create a beautiful graphic and i put it in a new tab ( large on 1 column),

I see in a forum, its not possible to put 1 column in a home page

So i wanna know if its possible to inverse my new tab (1 column) with the home page (2 column) for get my graphic on 1 column in home page

Thank you in advance for your answer.

It is possible to put a 1 column homepage…

When you add a new tab, you’re given the option to have 1 column.
