Div "eating" in to an image above - What's the terminology? - javascript

From what I can see the div below sort of eats into the image above as you scroll down creating what I think is a nice visual.
My only problem is I don't know what the terminology is to search for a tutorial on the process itself.
Does anybody know what search term I would use to find a good tutorial? I have literally tried everything I thought it might be called.
Example on a site where it is used: http://www.anakin.co/en

The term is called parallax scrolling.
The following link is a good tutorial, and explains how to achieve this in just CSS.
http://keithclark.co.uk/articles/pure-css-parallax-websites/.
Regarding the cutout effect I believe that is called clip masking.

The main content is on an overlay. If you look at the code though, in the css you'll see the "clip" property. It's since been deprecated, but it's been replaced by "clip-path". Showing parts of an image is called clipping/Masking and I believe you can find what you're looking for here:
https://css-tricks.com/clipping-masking-css/
EDIT: The background image is using parallax, which gives the background image "motion" when you scroll. But the actual effect of having that background show through is the clipping/masking in the article.

It's called Parallax scrolling http://en.wikipedia.org/wiki/Parallax_scrolling

How to reveal underlying image using css or js

I want to have one image above another one that is being revealed on scroll.
I am thinking of a similar effect as on this page: https://affinity.serif.com/de/photo/ (live-filters section, called "fixed-scroll" here).
Preferrably a native CSS solution or with as little JS as possible.
So far, I've found this example https://tympanus.net/Blueprints/ScrollingLayout/
It's almost what I want but I can't think of a way to make the background-attachment fixed to the element's parent rather than the whole viewport.
It only works when it's fullscreen and there's nothing above this effect.
I've also thought about a solution using translate-y but can't find a way to slide the top image up revealing the image underneath instead of sliding the lower image upon the first one.
Can you help me out here or point me in the right direction, how this may be achieved? Thanks!
As far as I know using background-attachment: fixed might be the only way to achieve this particular effect using only CSS, but it looks like that doesn't quite solve your problem.
I would try a simple parallax scrolling library such as parallax.js. This uses javascript to achieve the desired effect but you can apply all the code via CSS data attributes, like so:
<div id="mydiv" data-parallax="scroll" data-speed="0" data-image-src="/path/to/image.jpg"></div>
With data-speed="0" the image inside the div will be stationary as you scroll past.

Scroll speed manipulation css jquery

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,

Change text with a transition effect (zoom / fade)

I came across this interesting effect over at http://birvacreativestudio.com/theme/birva200/index.html The one I am talking about is the changing text (Probably the first thing you'll notice)
I got inspector out to see how it was done, but can't figure it out, Is the developer using purse css for this or some sort of mixture with javascript/jQuery?
Could anyone explain to me how to replicate it with jQuery? Are there any plugins/libraries that are good for these type of effects?
They're using Owl Carousel.
See the FadeUp transition here: http://owlgraphic.com/owlcarousel/demos/transitions.html
You can get great text animations easily with this JS animation platform:
http://www.greensock.com/gsap-js/
(just look at the animated header on that page, you'll see what can be done with this + its faster then jQuery animate)

HTML5 CSS3/Javascript Blur Mask

There are many of us looking for a Javascript/CSS3 solution that can provide a windows7-like UI within a webpage, without using flash.
We need an Opacity mask, rounded borders, and a Blur...
We've got the Opacity and the rounded borders, now we need to be able to apply some Blur effects to a semi-transparent Div.
I tried the BlurFast effect from the Pixastic Library, but it only blurs the actual image, not the background we are seeing trough the image...
Basically, we want a Div to act as a Blur Mask over other contents...
If someone actually succeeded with this, i'll be glad to know its possible :) Thank you
http://t.co/fFLPKnzC
very good article on blur showing the state of the art
sadly "masking" parts of your page, that blur everything behind, is not that easy.
maybe the suggestions in ths blog help you out, as they are very straight forward and from a totally different direction..
therefor to embedd html within svg and use svg-filters on html elements later on
Thought this could be relevant: Aero
Personally, I think the fact that the author states this to be "In other words, one of the most messy and most ineffecient implementations ever"... AND that he can onlt get the effect to work in a single browser... to be extremely telling.
There is no way to do this efficiently or cross-browser at the moment.
The only way you might be able to do it is by using Pixastic to create the blurred image within Canvas, export as dataURI, then use that image as the background for your div. If the div moves, then the positioning of the background-image should move accordingly.

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.
