Another smooth scroll approach

smoothscroll.js

		$('a[href*="#"]:not([href="#"])').click(function() {
			if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
				var target = $(this.hash);
				target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
				if (target.length) {
        	  offset = 100; //px, enough to clear the sticky nav menu
    				$('html,body').animate({ scrollTop: target.offset().top - offset }, 600);
    				return false;
				}
			}
		});
