Move section up behind header area on homepage

Site URL: https://matey.app

Hello! I'm trying to move the top section up to the top of the screen instead of having it start under the header area. I only want this on the homepage. Here's a screenshot illustrating what I mean. Thanks in advance!

You mean reduce header padding top/bottom???

@tuanphan I believe I already did that and reduced the header's vertical padding to the minimum 1vw. Is there a way I can shift the first section up to begin from the top of the screen, rather than below the header? 

@tuanphan Thank you worked perfectly!
