Reducing padding on gallery section, no section id's working with css

Site URL: https://www.northwoodsfarmny.com/

Hello everyone, 

I cannot for the life of me get my css to work with any of my section id's 😞

I am mainly trying to reduce the white space/padding on certain sections.

For example the gallery slide show at the top of the page has a huge amount of empty space between the navigation bar and section underneath it. I have already set the lowest height I can on the site styles/section but doesn't seem to be doing the trick.

Can anyone let me know how to tighten this up and get things looking a little more clean? Any help is very much appreciated.
