Scroll speed manipulation css jquery - javascript

Find out a website http://www.boy-coy.com/#home. When you scoll down all content scrolls very smooth. Even if you scroll it fast, scroll is done at specific speed. This makes the website faster and responsive. How this can be achieved with the help of css and jquery?

At first glance.
Try reading their html source code output.
They use a few jquery plugins and legacy browser js plugin calls.
They have a custom and partially obfuscated .js script that is in depth, but you can see the specific properties it is setting on items in the page.
Barring any terms of use issues, you could likely decipher this pages cool scroll technique by working with this sample code as an example. But it is definitely a fair amount of work to write from scratch or post the entire solution here.
Im going to go and look for a smaller example that isnt as involved as this parallax.
And check out this link http:// codepen.io/JTParrett/pen/BkDie its got some starting principals here of some of the images positioning at different locations in the viewport when you scroll.
This link in SO can also help Can I change the scroll speed using css or jQuery?
Kirupa has a nice tutorial that can likely help in getting the smoothe scrolling effect stared too. http://www.kirupa.com/html5/smooth_parallax_scrolling.htm
And this one is pretty awesome. I think I would look into this demo. Be sure to test all of click event demos here. Im sure you could tie in your jquery tween event for the scroll bar with this http://plugins.compzets.com/animatescroll/
Another decent example http://bassta.bg/demos/smooth-page-scroll/

It is called Parallax,

HTML5 auto scroll to next section

As you can see right here: https://www.sequoiacap.com/
I'm trying to mimic its scrolling behavior right here, and its implementation really baffles me. Is it scrolling to another section? Or is it scrolling the background? Is there a name for this specific website style?
I have a one page parallax theme that I would like to auto scroll for user, so that each scroll gives the user a new fullscreen section. I would like to know how many plugins I would need to use. Some basic examples or directions for research would be greatly appreciated.
Thank you.
Here's 2 possible ways out of many, for how you could implement this:
jump.js which is a dependency-free library (meaning it does not require jQuery or similar)
fullPage which is a full page slider plugin for jQuery. This might be more of what you want, because it does not introduce a scrollbar.

Sticky scroll for two images

I've been trying to figure out how to create a sticky scroll effect on two images, basically like this: http://www.nationalgeographic.com/americannile/
(scroll down to see you will see the four images with sticky scroll effect)
I have tried some jQuery plug-ins but still couldn't figure out how to create the effect I wanted.
Any help would be greatly appreciated, or just a point in the right direction.
Many thanks
What You want to do is apply some actions when document scroll position changes. Since You are using jQuery, there is plugin exactly for this functionality called ScrollMagic, and here are the demos.
The link you posted uses the scrollr library:
https://github.com/Prinzhorn/skrollr
I've also used this library and I just can recommend it to you. It is really easy to use, for basic animations you don't need any javascript, everything is done via data- attributes.
It even supports mobile devices to some extend.

Free scrolling and parallax issue (jQuery Scroll Path + Parallax)

in a project where I need to build something like the famous parallax-powered Mario Kart Wii Experience site, which also comes with horizontal and vertical scroll (if you haven't seen it, here it is: http://www.nintendo.com.au/gamesites/mariokartwii/#home)
For the scrolling effect, I grabbed the JQuery Scroll Path plugin (website here: http://joelb.me/scrollpath/), and it seems to suit my needs concerning the free scrolling.
The problem comes when I try to include some plugin to generate the parallax effect. I tried several plugins (including Stellar.js, jInvertScroll, Parallax.js, Parallax-JS), but none of them seem to work properly. I assume that there's some kind of relationship between the custom scroll that comes with the Scroll Path plugin and the need of the parallax plugins of working with the navigator scroll to make the effect work.
I searched in Google for some similar situation (i.e., implementing Scroll Path with some parallax plugin) but I didn't find anyone in my current situation, and it seems that the Scroll Path plugin isn't maintained anymore.
Any idea for making it work would be appreciated!
PS: Sorry for the grammar mistakes, I'm still in process of learning english.
To make 2 plugins working together you should understand how they work. Parallax effect is achieved with few layers that are moved with different speed - the closest to you moves fastest, the most distant moves slowest. Most of the parallax-effect plugins are based on scrollTop calculation - i.e. layers are moved depending on current scroll offset multiplied by delta-value (which differs depending on layer position).
In your case you should connect jQuery ScrollPath scroll event to parallax plugin. In ScrollPath you should generate scroll event (that will be handled by parallax plugin) in function scrollToStep (look at row 490 in jquery.scrollpath.js). To make calculations simplier you can use 'top' value applied to scrollbar * some delta (you should pick out delta value by yourself). Then in parallax plugin you should modify event handler that applies parallax effect from scroll/mousewheel to event you generate in ScrollPath plugin.
To connect 2 plugins together you should modify their code which means that you won't be able to easily update these plugins to newer version. You should make comments to all your changes in order to reapply them if plugins will be updated in future.

Vertical Scrolling Effect in Javascript

I stepped a little too far over my head in a job I took this week.
I need to develop a scrolling, changing background like the one on Chevy's home page: http://www.chevrolet.com/
Something like this might suffice though: wearethescenery.bigcartel.com/
Any help would be appreciated.
There are plently of plugins available for jQuery to do just that:
25 jQuery Image Gallery/Slider Tutorials and Plugins
57+ Free Image Gallery, Slideshow And Lightbox Solutions/
You could animate the background-position.
You need a large background image for that, which might slow down the page load.
If you are not against using a javascript library, this jquery tutorial might help you solve your problem.

Graphic Scrollbar modification on Auto DIV Scroller script

We're using this autoscroller script: http://scripterlative.com/files/autodivscroll.htm (the bottom version).
However, we got really stuck since we don't know how to replace the moving "scrollbar" on the scroller side with a pure and simple line with up arrow on top and bottom arrow on bottom.
Functions wise we want this sidebar to behave exactly like the original sidebar and of course be cross browser compatible. We just want to get rid of the original scrollbar and replace it with a much cleaner and more stylish style.
Is this doable?! How?
Best regards Stefan
Just found jScrollPane on AjaxRain.
Implementing an autoscroll would take some coding, but should definitely be possible by just sending the click messages to the div manually so that it would do the scrolling. If it looks like this will suit your needs, I'd chip in with some additional implementation code. That topic may actually be better suited for another question, if you decide on jScrollPane.
Edit: updated link above. also, there are demos there for scrolling on hover and clicking on a link to jump to an anchor. Custom code for an autoscroll should be relatively simple to write from there.
