I just set the section hight to small and the width to Large and the padding is reduced. Just needed the correct combination of settings: https://translegal-llc.squarespace.com/home-3
Would like to reduce the space above and below the slider even more, but am thinking that the way gallery sections work in 7.1 I am stuck with the default minimum space (10) between sections.
Am still learning how to target sections, so thanks for showing me how to use the [data-section-id=""]
