Scroll to div on clicking the div

Here is the fiddle link https://jsfiddle.net/hitech0101/5vhdm5hy/
$('.block').click( function () {
$('#mainContainer').animate({'width':'20%'}, 1000);
$(this).css({'background-color':'blue'});
$('.block').css({'display':'block','width':'100%'});
$('.second').css({'display':'inline-block'})
});
In the fiddle, i am using jquery to convert the horizontal blocks into vertical blocks. I have changed the block color from red to blue when the block is clicked. When i click a particular block i would the scroll to move to the location of the block in the vertical view. I have tried jquery's scrollTop() method but still could not get it working the way i wanted it to. Please help.
The fiddle is partial representation of the webpage i am working on. There is more content on the original page which i have excluded. The maincontainer is the second container on the page.

No JavaScript necessary. You can specify an element in an anchor's href and it'll scroll it to the top of the window, including itself.
Wrap the div in an anchor or just use the anchor tag itself, they're both wrappers.
<a href="#scrollToMe">
<div id="scrollToMe"></div>
</a>
Just remember that it can only scroll the element into view to the best of its ability, if the item is at the bottom of the parent element the scroll will hit the bottom and it won't be able to go any further.

$(this).get(0).scrollIntoView();
Add this line into the .click function.
Fiddle

I suggest you get the offset top value and animate the #maincontainer to that position
$('.block').click( function () {
$('#mainContainer').animate({'width':'20%'}, 1000);
$(this).css({'background-color':'blue'});
$('.block').css({'display':'block','width':'100%'});
$('.second').css({'display':'inline-block'});
/*below is what i was talking about*/
var pos = $(this).offset();
$('#mainContainer').animate({ scrollTop: pos.top });
});

$(document).on("click", ".block", function() {
var _body_html = $('html, body');
var _scroll_to = $('.scroll-to');
var _top = _scroll_to.offset().top;
_body_html.animate({
scrollTop: _top
}, 1000);
setTimeout(function() {
_body_html.finish();
}, 1000);
});

jQuery onScroll() show and hide DIVs

I have a simple onScroll function, which shows a DIV when the scroll (down) height is 100 for example, and then if scrolled up soon as it reach 100 it hides the div, works perfect.
However, if I scroll down quickly and while its showing the DIV if I quickly scroll up & down 2 three times, it doesn't catch the event, even if its up again, it still shows the DIV, but again if I scroll even 1 pixel down, it hides it and if reaches 100 then it shows DIV again.. I hope I made it clear, I dont have an online demo as I am working on localhost.. below is my function that I am using standalone in the template within just <*script> tag..
jQuery(document).scroll(function ($) {
var y = jQuery(this).scrollTop();
var hoffset = 100;
if (y > hoffset) {
// show div
} else {
// hide div
}
});
Can someone please guide me to right direction, what other best approaches can be done for this, basically I am doing this for header nav div..
regards

Do you want like this? See my Fiddle
I use fadeIn() and fadeOut() instead.

The only way I found to stop animation, while its in the process is below and works..
jQuery('.thedivclass').stop(false, true).slideDown();

fixed div while scrolling which moves other elements in a menu

I have some menu items on the right hand side of my website that are: -
Basket Summary
Best Sellers
Quick Links
etc
I want the basket summary to follow down the page as the page is scrolled, I know how to this using position: fixed, but I need it to also move the other elements out of the way otherwise it will just overlap them.
I was looking at this: jsfiddle which would do the job and works but obviously thats only on button click, I would need to adapt this to scroll via jQuery.
I have read many tutorials for floated fixed divs but they are all for one div and don't have any other divs to interact with.
Any ideas if possible and/or how to do it?
Code from js fiddle as follows: -
$(function() {
$('.upButton').click(function(e){
var $parent = $('.highlight').closest('.box');
$parent.insertBefore($parent.prev());
});
$('.downButton').click(function(e){
var $parent = $('.highlight').closest('.box');
$parent.insertAfter($parent.next());
});
});

Is this what you're looking for?: http://jsfiddle.net/cmontgomery/YVh4q/
essentially, whenever the window scrolls check to see if your section is in the visible area and if not, adjust accordingly:
$(window).scroll(function () {
var mover = $("#sidebar .quick-links");
if($(window).scrollTop() === 0) {
//console.log("to top");
mover.prependTo("#sidebar");
} else if(!isFullyInViewableArea(mover)) {
var parent = mover.closest('.section');
if(isBelowViewableArea(mover)) {
//console.log("moving up");
parent.insertBefore(parent.prev());
} else {
//console.log("moving down");
parent.insertAfter(parent.next());
}
}
});
I must admit, this solution is not the best user experience, i.e. it jumps instead of scrolling smoothly. If it were me I would put the movable section as the last item in the right column and move that down the page with absolute positioning so it follows the top of the view-able area exactly.

Use this
Drag & Drop is best.

How to slowly move header while user scrolls the page?

I want to achieve the effect that is used on this Header on this example website:
http://anchorage-theme.pixelunion.net/
You will notice that as you scroll the page, the header slowly moves upward until it disappears from view. I want to achieve this same effect. I believe it will need some JS and CSS positioning but still have no clue how to achieve this. Is this done with parallax scrolling?
Would appreciate if someone could give me a quick example of the code used to do this with a element. So I can then use it on my own site.
Cheers.

the $(window).scroll(function () {...}) is the one you need here
$(document).scrollTop() is the amount of scrolled distance from the top

Use this:
$(window).scroll(function(){
if ($(this).scrollTop() > x){ // x should be from where you want this to happen from top//
//make CSS changes here
}
else{
//back to default styles
}
});

jQuery - If I'm moving a div with the keyboard

If I have a div with a fixed height and width, which I am moving using keypress (or keydown/keyup). Can I get the window to "follow" that div?
I know you can auto scroll a page, but can you get the co-ordinates of a div and scroll the page as the div moves?

are you using a javascript framework? If you use jQuery you can get the position of the div using:
jQuery('#yourdiv').position().top()
jQuery('#yourdiv').position().left()
Also, if you use jQuery, the window will automatically scroll to keep the Div in view anyway with no further work from you.
In response to your comment:
You can use jQuery('body').animate({scrollTop:xPosOfDiv});

One way:
$(document.body).bind('keydown', function(){
$('#somediv')[0].scrollIntoView(true);
});
Another way:
$(document.body).bind('keydown', function(){
$('#somediv').css('top', $(window).scrollTop() + 'px');
});
Smooth way:
$(document.body).bind('keydown', function(){
$('#somediv').animate({'top': $(window).scrollTop() + 'px'}, 1000);
});

var pos = $("#theDiv").position();
window.scrollTo(pos.left, pos.top);
