Fullwidth background of #gktop1 (more than one module)

Hi,
I need to insert an image background (possible parallax?) in the position #gktop1; fullwidth up to page borders. This position contains 2 o more GkNews modules.
Example url : http://www.farmaplanet.it/golf/index.php?lang=it
Thanks

...nobody has encountered this problem ?

Please add this code to override.css and make sure override is enabled in template settings.

Code: Select all

#gkPageContent {
background-image: url( path to image goes here );
background-size: cover;
}
