A Common Problem
How To Hide A Divi Background Image on Mobile
I see the question of how to hide a Divi background image on mobile over and over in the Divi Facebook groups. Some wonderful helpful folks offer solutions, but many times it is difficult for less experienced users to understand. NOTE: adding two sections and hiding/showing one of them on desktop / tablet / mobile is not a best practice. To make matters worse, there are zero answers on Google (until now) for this question. I decided to give you the combined solutions here for both regular and parallax section background images. If you like this, maybe you could check out my child themes for sale to show some support 🙂
