I would like to embed Google Maps across the full width of the template in a module position. Is that possible?
Vgl. attachemend (created by photoshop):

Yes its possible.
Therefore open the module and add a style to your iframe, like this

Thank you for your prompt reply.
Nevertheless, Google Maps remains in a box.
I'd like the map to be drawn the full width of the page, just like the graph with the sky at the top of the page.

Hi there,
full site width is not possible because the template width restriction.
Otherwise you have to edit the layouts/theme.php and remove the uk-container div from your prefered module position
