Dear @gridch
Position:fixed is the correct way to go i think in your case,
The fixed text being a part of the fullscreen slider, am i correct that it has the id:
#dalt
?
You will need to test obviously but you could load this CSS command earlier by adding it > Lay Options > Custom CSS & HTML >
Custom <head> content or Custom HTML at top:
<style>
#dalt {
position:fixed !important;
}
</style>
Need to test, and see! :)
Best
