Remove white space around Collection Description & Collection Header in Galleria Theme

[NSMT]

How do I remove the whitespace above and below the Collection Description and the Collection Header in the Galleria Theme?    I've looked at a bunch of questions similar to this and tried making the suggested changes but not having any luck.  The big thing is that the Galleria theme doesn't seem to have a "base.css, style.css or theme.css" file in Assets.  So I'm not sure where to make changes.

Thanks so much!
