SmartSlider module in Header position

Hello everyone,
I try to place a smartslider 3 module in the header position. The slider has a fixed size and I do not want it to occupy the entire width of the screen so as not to deform the proportion of the slides.
The problem is that I have no way to place the module in the center, it always stays to the left.
I have tried modifying #gkheader but I can not get the module to be centered.
Sending screen because I am working in local.
Thank you very much...

The template was not to blame, the problem was in the configuration of the slider
Sorry for the inconvenience, the problem is solved.

Hi
