Just looking around the Goog cause that’d be sweet if it works.
The “floating” elements are positioned “fixed”, which means they are taken out of the regular document flow. This means overflow:hidden; does nothing.
I see that you’re using a library. I assume the library requires the elements to be fixed positions…. maybe see if you can roll your own parallax effect?
I hope someone has more insight than I! This would be sweeeeet!
