Hi Paul and thanks for your fast reply.
The thing is, that if I use the Hero within a Page, the background image wil be full page width and the Hero content wil still be limited to the general content width. This is the wanted situation. When using the Hero from module though (and setting the layout as you sugest to Fluid) the content of the Hero will then also be in full page width wich is not the wanted behavior. Does this makes sense? :-)
By the way, I am using the Helix Ultimate.
Best regards, Morten
