Trying to add more padding on either side of my store in 7.1, but can't seem to find a code anywhere? I'm assuming I would add the code to the store's advanced header?

Hey,

I had a quick look and this CSS should work

you can play with the numbers to see what works for you best
 

.tweak-products-width-inset .products.collection-content-wrapper {

    max-width: 1800px;
    padding-left: 8vw;
    padding-right: 8vw;
    margin: 0 auto;

}

PS: this might affect mobile as well, so you can exclude the effect below a specific browser size:

@media only screen and (min-width: 640px)
{.tweak-products-width-inset .products.collection-content-wrapper {

    max-width: 1800px;
    padding-left: 8vw;
    padding-right: 8vw;
    margin: 0 auto;
}}

@ArminB this worked perfectly--thank you!
