Portfolio page setup

Hello!

I am trying to add a margin to the left and right of the portfolio pages so essentially the thumbnails are smaller. Is this possible? I can't add a spacer like I would a normal image. Thanks

Add to Design > Custom CSS

/* Portfolio margin */
div#gridThumbs {
    padding-left: 30vw;
    padding-right: 30vw;
}

Do you want to reduce spacing here on mobile?
