Container t3-sl t3-sl-1 (empty space)

Hi!
I've deactivate all module above content position in every page, except in pages containing an article.
But I'm seeing an empty space above all article.

With the debugger's help I see "container t3-sl t3-sl-1" occupies space which I would like to eliminate.
How can I do?
I don't want eliminate it forever, but only in article's pages.

Thanks.

Here two screenshots:
