How to use animate.css on :before elements?

Question

css

Hello, I'm animating elements using animate.css and js like this:
$(document).ready(function(){
$('.header_container_fixed').addClass('animated fadeInLeft');
});
but for elements :before doesn't work, how can one use ?

Answer 1

Doesn't work because it's not provided. Duplicate classes from animate.css for pseudo-elements yourself

.animated__before::before {
  -webkit-animation-duration: 1s;
  animation-duration: 1s;
  -webkit-animation-fill-mode: both;
  animation-fill-mode: both;
}
