Simple jQuery script to make part(s) of the site sticky when scrolled beyond a certain point.

StickyScroll.js

// sticky scroll function
function ScrollNav() {

	if ($(document).scrollTop() > 0) {

	} else {

  }	
	
}

// initiate the code on load for when a user has scrolled before and refreshed the page
ScrollNav();    

// initiate the code on scroll. note that this doest work nicely on iOs, but there is no viable workaround for this yet.
$(window).scroll(function(){
	    
	ScrollNav();    
    
});
