I am attempting to have two boxes sit side by side, but the second box insists on dropping down instead of staying side by side. I have tried a lot of different settings inside the Box Inspector, but no luck yet.
FlexBox did the trick! Although my solution may not be perfect syntax, the result I was after, was achieved.
Studying the guide you linked to a bit more and a little more experience, might produce a cleaner or simpler solution, but it looks good for now.
Thanks for your time and link to the other discussion.
