How do I make an page header animation?

I had to create a very fast and optimized page that had a sophisticated header on-scroll animation ( like 3D parallax ). I could add TweenLite+CSSPlugin ( 21.09KB ), but decided to add nothing more. So this is kind of the most simple, Vanilla JS, yet very flexible and fast header scroll-in effect;. What is a page header animation? How do you make a page header animation?

document.addEventListener("DOMContentLoaded", function(){ //needed to get scrollTop position on IE9- var documentElement = document.documentElement; //Heder height var targetPosY = 500; /* A couple of notes here 1) For such a thing, normally I would just use a TimelineMax. It is amazingly flexible and is tend for just this kind of animations. The idea of this pen is to make things fast and simple as possible; 2) Actually, I can pass string to TweenLite.to("element ID", time, {...}); but I prefer to pass DOM Element 3) If you add your own TweenLite's and style it, actually can get pritty nice results */ var tweens = [ TweenLite.to( document.querySelector("#box1"), 1, {css:{force3D:true, scale:1.2, y:100}, paused:true}), TweenLite.to( document.querySelector("#box2"), 1, {css:{force3D:true, scale:1.6, y:200, x:-100, alpha: 0.5}, paused:true}), TweenLite.to( document.querySelector("#box3"), 1, {css:{force3D:true, scale:2.6, y:150, x:50, rotation:45}, paused:true}) ]; window.onscroll = function (event) { ( !! window.requestAnimationFrame) ? requestAnimationFrame(onScroll) : onScroll(); } function onScroll(){ //have to restrict it into range, because on OSX it can get negative values //http://bassta.bg/2013/05/restrict-a-number-to-a-range/ var top = Math.max(Math.min(window.pageYOffset || documentElement.scrollTop, targetPosY), 0); if(top <= targetPosY){ var progress = (top / targetPosY); Array.prototype.forEach.call(tweens, function(tween){ tween.progress(progress); }); } }
