Page section padding 7.0 Brine template

Is there a way to reduce the padding of a page element?

I've added a page element to an index section to act as a footer. But there is no way of reducing the height of the page (see photo)

I tried a code from a different post thread which didn't work:

#collection-5fcfa621faf0bc04d1d550c2 #page {
   margin: 0 auto;
   padding: 0px 0px;
}

The code only needs to adjust this single page height?

Thanks in advance

Add to Design > Custom CSS

/* Footer height */
section#new-page>div {
    padding-top: 5px !important;
    padding-bottom: 5px;
}
