Using PHP:

jQuery: Scroll sidebar with window. (It's necessary that the sidebar it's absolute positioned and have a wrapper with absolute position too)
jQuery(document).ready(function() {
var page = jQuery('.single.post');
var sidebar = jQuery('.single.post .scrolling-sidebar');
var content = jQuery('.single.post .content');
// Scroll with screen
var top = sidebar.offset().top;
var limit = top + page.height() - sidebar.height();
// Define sidebar-wrapper height
