Right-click on the section settings icon (3 horizontal lines) and disable the new section on tablet and mobile. (This will be your desktop version with the sidebar line. It may be a good idea to “Rename” the section – or modules within the section – for reference.)

Red for disabled, blue for enabled:

Now disable your old section on desktop. (This will be your tablet/mobile version, which won’t have a sidebar line, as sidebar items are stacked vertically under rest of page.)

Finally, apply the following CSS to website (adjust to right border & padding if you have a left sidebar, etc.):

padding-left: 30px;
}

 

Where to paste the CSS snippet

Copy and paste the above snippet into one of the following two places (depending on where the rest of your custom CSS code is residing):

1) Navigate to Divi>Theme Options and at the bottom of the default “General” tab, paste the CSS snippet into the “Custom CSS” box and save changes.

Child Themes

We recommend using a child theme. It is your insurance against losing your custom work in updates. Click here for instructions on adding a basic Divi child theme with a stylesheet (for custom CSS). Click here to learn more about child themes and getting the most out of the Divi theme.
