Like most configuration in Regolith, the i3-gaps gap size can be tuned via Xresources (See here for all Xresource definitions).

1. Create or add the following value to your ~/.config/regolith2/Xresources file:

i3-wm.gaps.inner.size: 20

In this example we’re setting the default gap to 20 pixels.

2. Reload the Xresources configuration:

$ regolith-look refresh
