What it is
A short tutorial by Adam Khoury on building a parallax scrolling effect in plain JavaScript. It explains the idea of layers moving at different speeds, compares it to Disney's multiplane camera, and builds the effect with essentially one line of code tied to the scroll event.

using this parallax function, an image that's in front of the background will scroll along the users scroll, heres a great tutorial video on parallax step-by-step: [this video] and lastly here's the code: function parallax() { var topdiv = document.getElementById('topdiv'); topdiv.style.top = window.pageYOffset + 'px'; } window.addEventListener("scroll", parallax, false); topdiv = target image you want to move while user is scrolling. it's id belongs to a div element. in order for this to work you must have a background image in the body that is *fixed. then use div to call another image *the moving image in a div element (or possibly other ways), then add in this function and that's it, as for c

I'm trying to add Parallax Scrolling to a website that is already designed. It isn't working for some reason. Can someone assist? The tutorial that I was using is this one.

I'm trying to make a parallax effect according to this tutorial [this video] But my function doesn't apply to my objects.

My objects just stuck at the same place when scrolling. Here's the JSFiddle example: jsfiddle.net/hkbusbkm
