Node content displays horizontal, not vertical

Hello,
The w3css theme is not for admin users (editor display) it is for regular users (viewing the saved content). Drupal has some themes built for admin users as Claro in Drupal core. I recommend using an admin theme and allow the editor in the permissions to view it.

Go to your-site-dot-com/admin/appearance
and scroll to the bottom under "Administration theme" and select Claro.

Go to your-site-dot-com/admin/people/permissions
and search for "View the administration theme" then enable this option for editor role.

I am using https://www.drupal.org/project/gin →

Best wishes,

Mmm, OK, fair. I hadn't considered that the theme wasn't intended for users in an Editor role. That helps. And I'll keep it in mind for future expectations.

Given that I'd like the layout to be vertical instead of horizontal when viewing, do you have any hints as to where I should start? I suspect that there's *something* I can change in the CSS to do that. Or do you advise against that?

I should have started by thanking you for the work on this theme & support; it's great to see someone put in so much valuable effort out of their respect for the community. I'm beyond impressed and appreciative.

Thank you! If this is a multi field you can use a quick custom css class I have in the theme settings. your-site-dot-com/admin/appearance/settings/drupal8_w3css_theme and click on "Advanced Site colors" then go to "To Disable" and copy "w3-expand-fields"
and insert it in "Page Wrapper" text field.

If it is not working then you can apply some CSS in two ways:
1- Create a custom sub-theme ( https://www.drupal.org/node/2866181#d8w3css-sub-theme → ) and add the css in the styles.
2- Install this module ( https://www.drupal.org/project/asset_injector → ) and inject the css.

Best wishes,

It worked, hooray!
