Hello,

Thanks for your reply. From what I can see this solution will work in the way that each of custom post will have same background.
But actually each of our custom post will be a separate offer with different background photo.

Well, it seems that custom posts are not a good idea at all. Too many things to set up and further customize.

Do you have any good, reliable developer that you can recommend? On UpWork. I have some work to do where I’m not able to do by myself.

Thanks one more time for your help.
