Getting rid of white border that shows after changing project pages' background color

Site URL: https://brianbilesdesign.squarespace.com/forager

I changed the background color of a few project pages but there is a white border at the bottom I can't figure out how to get rid of. How can I change it to the color of those pages? Thanks!

Thanks! It worked

These, I figured out how to make the links white but the underline rollover is still black.

Add these code 

#collection-629160b12111db0746ab9b5d {
  #mainNavWrapper .nav-item a, #secondaryNavWrapper .nav-item a {
    color: #fff !important;
  }
}

It's working on the first link but not the other 3?

I have updated the code. Please add new code
