Thank you! I was having trouble getting my text/button on top of my background to stay behind my ensuing sections. My mistake was not setting the sections to ‘relative’ from ‘static’ as you did in your demo (and I couldn’t find ANYTHING in university for this. Little settings are so critical!
Did you ever figure out how to handle the ‘jumpiness’ in mobile browsers that come from the navigation and tab bars disappearing and reappearing that works for all mobile screensizes? causes the fixed stuff to move up and down slightly vs stay fully put…
