How to center align entire app while using vertical header

Hi All,

I have an app, which is using the vertical header feature. I’d like to center-align the body of the site (minus the vertical header, which should remain on the left side of the screen) but I can’t seem to get the desired result without also affecting the vertical header.

By default, the body of each page (all blocks) aligns with the left side of the screen.

Has anyone achieved this in their Softr application?
