Now the 4 boxes are horizontally aligned but shoved too far right when in CMS Edit Mode - both when CMS 'Edit' is shown and hidden(see attached). Still looks ok when not in CMS Edit mode. Don't mean to drive you crazy with this and I don't want to break the public(non-CMS) view. So I'll leave up to you if you want to take another crack or leave it be.
Thanks for your help with this.
