I see, Ninja just wanted to know how is the exact configuration used by JA in the template, I managed to add, but it's not inside the layout, it's on the edge of the browser.
Even the AddThis at the browser edge the space within the template continues even without the AddThis, if only the layout didn't have this space it could leave it at the browser edge without a problem.
See the image:
Thank you very much for your attention and help.
