Google map module

Hi,
I have made two installation of this template. One step by step and an other with Quikstart.
On the first Google map module shows this:

With the same settings I have this on the Qucikstart installation:

I would like to have the same module display on my site than with Quickstart installation : full width, centered and dark...

An idea ?

I changed the container for the section-8 in Layout settings of template from 'Fixed' layout to full layout.

Kindly check.

Yes thank you it's better now !
