Increase width of the Widget boxes

Hi there,

Which widget are you referring to?

Let me know :)

Hola Leo, I guess I was hoping to increase the width of all the widget areas... But in particular the widget on the site that says, "FREE MiniCourse"

There is nothing in the site settings that I can adjust to increase the widget box widths, right? Or does that need additional CSS?

The width of the sidebar can be controlled in the customizer:

If you are referring to the green area here, then that would be the widget padding:
