How can I reduce the spacing between sections especially with the spacing created by code with custom CSS?

Hello

I added several codes on top of each section to guide the table of content i had on top of my page. So the spacing between section(I've changed the spacing of each section to 0) is increased by one line of code. Even though I could get rid of the text inside the code, to make it look like a blank space. But the white spacing between each section now looks awkwardly large. I asked Squarespace help and they said it could be possible to reduce the spacing with custom CSS. I wonder if anyone here could maybe lend a hand. (I had absolutely no coding knowledge... or maybe just a little bit of python which is not helping here)

Thanks a lot!!
