Customizing Sidebar Width on the “Left Side Column” Template

If you're using the "Left Side Column" page template, you probably already know that you can set the sidebar width globally using Theme Roller under Layout properties:

But did you know you can also customize it on a per page basis? Just add some Inline CSS via Page Properties > CSS > Inline:

:root{ 
  --ut-body-sidebar-width: 20rem; 
}

This will override the global setting only for the current page.
