Enfold 2017 demo About Us gallery

Hello all.
I’m trying to replicate the team photo grid that you is on the About Us page on the Enfold 2017 demo. I’m using the horizontal gallery element but I cannot figure out the styling I need to add to add color to the padding background. If I place the gallery in a color section, I can’t get the gallery to span the width of the page. When I inspect the elements used in the Enfold 2017 demo, it looks like it’s a masonry grid but can’t get it to work right. Also, I’d like to link the images in this feature to subsequent team bio pages or find a way to create a hotspot over the images so the bio brief pops up on the mouse over. Can you give me some direction? Thank you. I set up creds for the moderators under private content if needed.
