I don't know how they did what they did. Very nice.My approach is:1. Create a banner for your biggest screen - say 2500px wide.2. Set your title for 2500 px. Then just drop the banner on it (don't set it as the background). Lectora will not compress it to fit. Move it to where you want it and lock it down.3. Reset your title to the width of your course - looks like 800. If you put it as the true background it will repeat. I think there is a way thru HTML to tell it to not repeat but I am not sure.
