How do I move an image section so that it's underneath my transparent header?

Hi!

So I currently have an image section right below my transparent header, which I need to move it 45px higher. I can't do this using the standard Squarespace options, could someone tell me what CSS code I can use to make this happen?

I attached an image to further demonstrate what I'm trying to do.

I can't use my image as a background image (which I know would work) because the background image formatting scales differently than the rest of my section images.

Any advice would be very helpful!

You are a LEGEND! It worked. THANK YOU!
