Hello,
Thank you for the fast answer.
I checked the page with Firebug, it’s a really nice tool, unfortunately I’m not good enough to see how they manage to put a slider with custom fields as background.
Tried to install and configure some NextGen plugins but all I’ve got is a basic slider that I can put in my pages.
Maybe the website uses the basic Customizr slider with some custom css ?
I have noticed that only the slider is moving, the container doesn’t move, so maybe, you have to copy the slider’s shortcode and put it as a background somewhere?
