Wow, I thought you would try and explain a little bit more than repeating what is already in the docs located here https://docs.metabox.io/fields/background/
I’m sorry I forgot to mention that I did try both of those methods.
So again I ask, maybe you can do a little tutorial and show me and others how to add a background image to a container. Nothing fancy, something super duper easy.
Trust me, it’s very confusing.
