Is this WordPress code causing page weirdness? Can’t scroll to bottom

It was Stellar parallax. Here is the offending code:

// Stellar parallax var $ = jQuery.noConflict(); $(function(){ $.stellar({ horizontalScrolling: false, verticalOffset: 40 }); });

I now need to go away and figure out what in this code was giving me the problem.

Thanks for the prompts of where to look.
