Force 2 columns in Divi on mobile device

On the mobile phone you can force 2 columns with the following code.

1. Insert CSS class

You can enter the CSS class in the Settings line

2. Insert CSS code

I insert the code into the theme options

Use the following code for this:

@media only screen and (max-width: 980px) {
.zweispalten .et_pb_column {
width: 50%!important;
