BRINE, padding

Hello guys 🙂

I have an issue, do you know how to change padding only in one gallery page? I want it to be smaller on both sides. 

But I don't want to change anything on my home page or other pages.  Only this one which is gallery page. 

I am using Brine. Here is a link for this page https://dorotaporebska.com/archive

thank you,

This code should help:

#collection-6370f9c1f56d1d793c9f108b {
 .tweak-site-width-option-full-background .Main-content {
   max-width:2000px;
 }
 .Main-content {
   padding: 0px 20px;
 }
}

Hope that works!

thank you so much:)
