Removing top and bottom padding on a portfolio section

Site URL: http://tonicabrandstudio.com

I'm trying to decrease/remove the top and bottom padding on this portfolio section, as shown in the attached picture. Any ideas how to do this?

Q2: is there a way to insert text into a portfolio section? If not, I guess I can just add another section on top once the padding is removed.  

Right now I have the portfolio set to hover: follow cursor

Thank you!!

@tuanphan thank you! Sorry, I have a couple of different threads going, asking questions in different places. 

But this works great, thank you so much!! But now, there's an issue with the images on hover. They are cutting in half on desktop, but working fine on mobile. any idea why that is?  

Okay. I'm checking it again
