Анимирование букв в слове

Анимирование букв в слове при прокрутке страницы, используя animate.css и wow.js. Чтобы анимировать каждую букву, скриптом буква помещается в персональный контейнер.


HTML

<div class="wrapper">
   <div class="scrollDown">SCROLL DOWN</div>
  <div class="placeholder"></div>
</div>

CSS

Дополнительно для анимаций потребуется библиотечка animate.css

JS

Также нужно подключить jQuery и скрипт wow.js для запуска анимаций реагирующих на скролл

Скрипт
/*

*/

new WOW({
  offset: 200
}).init();

var animateCss = [
  "bounce", "flash", "pulse", "rubberBand", "shake", "swing", "tada", "wobble", "jello",
  "bounceIn", "bounceInDown", "bounceInLeft", "bounceInRight", "bounceInUp",
  "fadeIn", "fadeInDown", "fadeInDownBig", "fadeInLeft", "fadeInLeftBig", "fadeInRight", "fadeInRightBig", "fadeInUp", "fadeInUpBig", "flip", "flipInX", "flipInY",

  "slideInUp", "slideInDown", "slideInLeft", "slideInRight",
  "zoomIn", "zoomInDown", "zoomInLeft", "zoomInRight", "zoomInUp",
  "rollIn"
];

var placeholder = $(".placeholder");
var colorCounter = 0;

for (i = 0; i < animateCss.length; i++) {
  var word = "<div class=\"word\"></div>";
  $(word).appendTo(placeholder);

  for (j = 0; j < animateCss[i].length; j++) {
    var letterDiv = "<div data-wow-delay=\"" + (j * 0.1).toFixed(2) + "s\"  class=\"letter wow " + animateCss[i] + " color" + colorCounter % 7 + "\">" + animateCss[i][j] + "</div>";
    $(letterDiv).appendTo($(".word").last());
    colorCounter++;
  }
