Separating two blocks by one line. SiteOrigin Hero widget.

Hi,

Trying to make adjustments.

Separating two blocks (with the SiteOrigin Hero widget in each) by one line. Using “Page Builder by SiteOrigin”. CSS applied with id=”pgc-6-1-0″.

What parameter does this CSS line add?:
(I haven’t set any parameters)
CSS: width: calc(33% – (0.67 * 30px));

Or, what parameter can be used to force the initial configuration of the line and its blocks?:
CSS: width: 33%;

Regards.
