Hello Peoples,


I'm trying to create this Split-flap Display style animation using GSAP. I've got two images, each split into a grid and upon clicking, all the squares has to flip, revealing the other side. I'm trying to make a nested timeline and to stagger the whole thing.


Here my code:


//Splitting image into a grid

var Split = function(tar) {
  this.$t = $(tar);
  this.gridX = 6;
  this.gridY = 4;
  this.w = this.$t.width();
  this.h = this.$t.height();
  this.img = $("img", this.$t).attr("src");
  this.delay = 0.05;

  this.create = function() {
    $("div", this.$t).remove();

    for (y = 0; y < this.gridY; y++) {
      for (x = 0; x < this.gridX; x++) {
        var width = this.w / this.gridX * 101 / this.w + "%",
            height = this.h / this.gridY * 101 / this.h + "%",
            top = this.h / this.gridY * y * 100 / this.h + "%",
            left = this.w / this.gridX * x * 100 / this.w + "%",
            bgPosX = -(this.w / this.gridX * x) + "px",
            bgPosY = -(this.h / this.gridY * y) + "px";

        $("<div />")
          top: top,
          left: left,
          width: width,
          height: height,
          backgroundImage: "url(" + this.img + ")",
          backgroundPosition: bgPosX + " " + bgPosY,
          backgroundSize: this.w + "px",


    .on("click", function() {

$('.split').each(function() {
  var split = new Split(this);

//Flipping animation


$('.split').on('click',function() {
var t1 = new TimelineMax();
t1.add([TweenMax.staggerTo($(".top").find(".segments"),1.0,{rotationY:"+=180",ease: Power2.easeIn},0.1),
  TweenMax.staggerTo($(".bottom").find(".segments"),1.0,{rotationY:"+=180",ease: Power2.easeOut},0.1)],0,"start",0


Can anyone help me on this?

Hi and welcome to the GreenSock forums,


Nice demo. We usually don't have a lot of time to help construct advanced effects like this as we like to focus our attention on the GSAP API.

However I have an idea that might help.


I think the problem is that everything inside .top is always going to be visually stacked on top everything inside .bottom.

A solution may be to just rotate each image 90 degrees like so:
