Slow down/stop/pause scrolling at a specific pixel - javascript

I'm looking for a way to slow down scrolling between two specific pixels, for example 1 to 100 from the top. Would that be possible in any way?
Here's a link to a website that have that feature I'm looking for.
http://goo.gl/isH5o0
When you start scrolling the dark blue overlay div disappears using CSS3 Translate3d, but then the scroll seems to stop or go really slow, which makes the underlying div not scroll to far at the same time the overlay div slides up.
Can someone please give me a hint of what technique to use to accomplish this or maybe help me with some code.

I think that there's nothing special with the scroll on that page, just the divs moving using 3d transforms. But if you want to achieve special effects with scroll, you can use the jQuery animate function:
$('html').animate({scrollTop: position-to-scroll}, 300, 'ease-in');
More about animate.

It may be using disable scrolling. I noticed that if i drag the scroller on the right hand side of the window it is uneffected by the "slowing" however the mouse scroll is. This is similar to the effect of the demo described here How to disable scrolling temporarily? .. at a point you can temporarily disable the scroll and then re enable it to stop them going too far down

Sliding an element "up" over another as the user scrolls down, without fixed positioning?

The wording in the title is weird, apologies. It's hard to explain the effect.
I currently have this, it works best on Chrome:
http://mattluckhurst.com/dev/
My client wants each panel to slide up as the user scrolls down, covering the previous panel. I am currently accomplishing this by setting the "current" panel to have position:fixed and top:0 as soon as the page scrolls to it. The panels each have a z-index that corresponds to their vertical position on the page. So ideally:
You scroll down. when the next panel is halfway up the window, the scroll animates to get you all the way there, then that panel is snapped to the top so the next one can come in over it.
It's working pretty well in Chrome, but I am getting a lot of flickering and stuff elsewhere. Also on mobile it's a mess, but we really want a nice smooth swipe up down.
I know fixed elements can get pretty funky on mobile, so I am wondering if that is the problem, or if I should be using something other than just window scrolling for the animation / effect.
I see more complex parallax stuff all the time, so this should be pretty doable, I'm just not sure where to start.
Thanks for any help! Let me know if you need more info.

smooth scroll to div on mouse scroll

I've looked through a lot of smooth scrolling stuff and none of them do quite exactly what I want it to do. I would like to encapsulate a mouse scroll, and automatically smooth scroll to a specific div. So there the user is never between two divs, the screen is always filled with the next or previous div. Kind of like a hyperlink that jumps to an #anchor but instead of a click, its a mouse scroll, and instead of a jump, its a smooth scroll/transition. Simplest solution would be best. I don't want to involve jquery...
Thanks!
There is a good plugin for doing what you want.

Is there a way to make scrolling finer for a scrollable object?

Let's say there's a scrollable <div> or <body> that has a height of 2000px. Everytime I use the mouse scroll, it will unfold 100 pixels. Is there a way to make the unfolding 10px instead of 100px?
So that the scrolling would seem to be finer.
There is a similar post answering what you want.
Change Scroll Speed with a fiddle for demo.
NOTE: I think this is a bad idea as far as use-ability and respect for the user. AND i dont think you can actually change the speed. You just 'fake it' by changing the amount of scroll over an element. If you had a wrapper around your page i suppose it would work.
If you want to get a parallax effect, there is some jquery plugins

jQuery - Continuously scroll div on hover

I wish to build a shelf of content much like on Netflix where when you hover over arrows on either end the shelf scrolls at a continuous speed. Ideally, I would also like to make it so when you click the arrows it scrolls a chunk along, so you have the option to click like made to get through a shelf quickly.
This will be using lazy loading so you don't need to worry about repeating content, but obviously it won't have a set width (other then the outside container being 100% with overflow scroll.
Also, this needs to be actually scrollable, so it will work on tablets/phones.
I have no idea here to start so any directions would be great.
Thanks,
Jake!

UPDATE: Check out the Smooth Div Scroll jQuery plugin. It slides continuously through the image, you can hover the mouse on the div and manually scroll back- and forward.
Original answer:
I might be off with that, but check out these two plugins:
jQuery Coverflow plugin or the jQuery Imageflow plugin
I think the keyword you are looking for is "flow" and there are multiple flow plugins for jQuery. Hope this helps.

Appending a Vertical Scroll to a Horizontal Scroll Bar

I've been trying to do something like this for quite a bit, and have tried a variety of methods from fake scroll bars and DOM-tricking code. Nothing seems to quite be as clean / functioning as I need it to be.
What I'm trying to do is have a horizontally scrolling div (with scrollbar), with a vertically scrolling div nested within it. Ideally the single horizontal scrollbar would scroll, and after a certain point--vertically scroll the "go-up" div next to it.
Here's an example diagram for those who need to visualize:
I think I have a solution that could work:
Basically I'm thinking that the horizontal "scene" could have overflow that equals the height of the "go-up" div. And after the horizontal width of the "scene" passes...you can, onScroll, shift the "go-up" container right using (ScrollLeft) and up using (ScrollTop).
Basically giving you the illusion of controlling it's vertical scroll with a horizontal scrollbar.
Check out the code here: http://jsfiddle.net/jPzqj/1/
I know how to pass a function at the end of the "scene"...currently I'm using:
$('#main').scroll(function(e)
{
if($(this).scrollLeft()>1430)
{
}
});
My only issue is I'm not quite sure how to approach the math that would allow me to shift the go-up container. How do I pass in the "scene" divs scroll value into the ScrollLeft and ScrollTop values of "go-up"...
Could anyone give me any advice on this at all?
Thanks.
You are totally off the right path, no vertical scrollbars are involved.
That is a good site (not the one that you make in 30 minute obviously), and the javascript is obfuscated, but if you are interested, you could watch the source with Firebug to understand what's going on.
It works by mixing a javascript library, some cool CSS3 Transform3D effects, and a nicely studied HTML to give you the effect of the screen scrolling up (actually, only the images are moving - and not scrolling - while the screen is always in the same Y position).
The same effect is used to create the percetion of depth, by moving the houses in background slower than the ones in front.
This effect is called PARALLAX SCROLLING .
A good javascript library you could start looking at for Parallax effects is Stellar.js
You can take a look at some great sites made with Stellar.js, especially Nike and Saucony.
Hope this answer saved you some time,
good luck on your studies ;)

this is what you want: Jquery Parallax Scrolling effect - Multi directional
