Empty space even when no article is pubblished

Hi!
I've created 2 website with your fantastic framework, but I've same problem in both sites.

I don't want any article in home page, but only in other pages.

No article is pubblished in home page, but there is an empty space in the section which should accommodate contents
Practically there is an empty space even when no article is pubblished!

Whit debugger, I'm seeing what occupy this space:

container t3-sl t3-sl-2
t3-mainbody


Please help me!
Thanks in advance!
