Does anyone have a recommendation for a Jumbotron stack that works with Source?
BWD Section Pro would be my choice
Have you got an example of what you want to recreate?
You should be able to build what you want using just the Source Container or Container Plus stacks.
Source is perfect for creating Jumbotron type sections from the most basic of the fixed Bootstrap type Jumbotrons to the fully adjustable type with any background you want. Source has everything you need and building Jumbotrons is easy…
Here’s an example that shows 2 Jumbotrons at the top of this demo site - https://www.webdeersign.com/pr21demo1/dm/demo3/
