How to add margin underneath header on 1 page only

Site Preview: https://ayngoac0mjth5ce9-63190401240.shopifypreview.com

I’m trying to add 160px more margin directly underneath the header on 1 page only.

I’ve seen suggestions for collections, product templates, entire themes… but I cannot figure out how to add it on only 1 page.
