Answer 1

Here you go. You have to do a couple of things.

• listen when the scrolling stops
• find the "next" container
• scroll to its top value, without triggering "the scroll end detection"

JavaScript

var items = $(".item");
var animating = false;

$(window).scroll(function() {
    clearTimeout($.data(this, 'scrollTimer'));
    if (!animating) {
        $.data(this, 'scrollTimer', setTimeout(function() {
            items.each(function(key, value) {
                if ($(value).offset().top > $(window).scrollTop()) {
                    animating = true;
                    $('body').animate( { scrollTop: $(value).offset().top + 'px' }, 250);
                    setTimeout(function() { animating = false; }, 300);
                    return false;
                }
            });
        }, 200));
    }
});

The "scroll end detection" is coming from yckart's answer to jQuery scroll() detect when user stops scrolling. All timings from this example can be adjusted to your needs.

Try this:

window.location.hash = 'your div id';

your updated fiddle : here

UPDATE
if you want to do this in a smooth way try this:

$(window).scroll(function() {
    var winScroll = $(this).scrollTop(); // current scroll of window

    // find cloest div
    var cloest = $('your main divs').first(); // first section
    var min = 10000;
    $('your main divs').each(function() {
        var divTopSpace = $(this).offset().top - winScroll;
        if( divTopSpave < min && divTopSpave > 0 ) {
            cloest = $(this);
            min = divTopSpace;
        } 
    });

    // animate
    $(document.body).animate({scrollTop: cloest.offset().top}, 'slow');
});

Working Sample DEMO

Try this

$(document).ready(function () {
    var full_url = this.href,

        target_offset = $('.item:first').offset(),
        target_top = target_offset.top;

    $('html, body').animate({
        scrollTop: target_top
    }, 500);
});

To get it to work in Firefox, use

$('body,html').animate( ... );

Answer 6

I found solution for what you want to achieve. You can change 200 on the following line so height from and to the top of the box will change.

if ($(window).scrollTop() < $(value).offset().top+200 && $(window).scrollTop() > $(value).offset().top-200 )

full code

var items = $(".thebox");
var animating = false;
    $(window).scroll(function() {
        clearTimeout($.data(this, 'scrollTimer'));
        if (!animating) {
            $.data(this, 'scrollTimer', setTimeout(function() {
                items.each(function(key, value) {
                    if ($(window).scrollTop() < $(value).offset().top+200 && $(window).scrollTop() > $(value).offset().top-200 ) {
                        animating = true;
                        $('body').animate( { scrollTop: $(value).offset().top + 'px' }, 250);
                        setTimeout(function() { animating = false; }, 300);
                        return false;
                    }
                });
            }, 200));
        }
    });

Following method will help to adjust Div scroll position so that selected inner Div is viewable in view port.

jQuery :

function adjScrollPosition(container, elem) {
var h = container[0].clientHeight;
var w = container[0].clientWidth;
var t = container.scrollTop();
var l = container.scrollLeft();
var b = t + h;
var r = l + w;
elem = elem[0];
var eh = elem.offsetHeight;
var ew = elem.offsetWidth;
var et = elem.offsetTop;
var el = elem.offsetLeft;
var eb = et + eh;
var er = el + ew;
var top = et < t || eh > h ? et : b < eb ? t + (eb - b) : t;
var left = el < l || ew > w ? el : r < er ? l + (er - r) : l;
// If you want to bring element in center of the view port uncomment following lines
//var top = et - (h / 2) + eh;
//var left = el - (w / 2) + ew / 2;

$(container).stop().animate({ scrollTop: top, scrollLeft: left }, 500);
}

                if ($(".text-danger").length) {

                    $(document).ready(function () {
                        $('html, body').animate({
                            scrollTop: $("form#partner-register-form div.text-danger").first().offset().top - 60
                        }, 1000);
                    });
                }
