targeting a section to decrease padding/margin

Hello,
I’m creating in MAMP. Was wondering how to decrease the huge gap between the person’s name and the bottom of the black header area?

Here’s a screenshot: https://chriscaldwell.com/my-images/home-3.png

I only want to target this group on my homepage from the Twenty-Twenty “Patterns” group.

Thank you!
Chris
