I'm trying to make a parallax effect according to this tutorial https://www.youtube.com/watch?v=D75WTf_Y738
But my function doesn't apply to my objects. Here's the function:
function parallax() {
var sphereOne = document.getElementById("sphereOne");
sphereOne.style.top = window.pageYOffset +'px';
};
window.addEventListener("scroll", parallax, false);
I know I can use hundreds of JQ libraries instead to achieve the effect, but want to understand what's wrong. My objects just stuck at the same place when scrolling.
Here's the JSFiddle example:
