basically want create galaxy s4 review - verge

you can use jquery waypoint plugin http://imakewebthings.com/jquery-waypoints/

with plugin can trigger event whenever top (or bottom) of window reaches element.

e.g.

$('#id_of_container').waypoint(function(direction) {   if(direction=='down'){     $(this).css('position','fixed');   } else {     $(this).css('position','');   } });
