Hey,
I honestly completely forgot about the layout and how it’s built in the theme.
The idea is that all content elements go inside a big wrapper that is 1170px wide. This wrapper houses everything in between the top slider/menu and the footer, so I’m sorry to say it won’t be possible to work around it, as the div with the map cannot extend more than what its parent wrapper allows it (hope that makes sense).
Yes, you could make that 1170px be 100%, but then this would mean a heck of a lot of work for all the page elements that are not RAW HTML, in order to re-center them.
Regards,
