Target :before and :after pseudo-elements with jQuery [duplicate]

Answer 1

Decided to go with the solution of adding a class on load to the element and then manipulating it in the css.

$(".lifted").addClass("on");

CSS

.lifted.on:before,
.lifted.on:after {
               opacity: 1;
    -webkit-transition: opacity 1200ms cubic-bezier(0.25, 0.1, 0.25, 1); 
         -o-transition: opacity 1200ms cubic-bezier(0.25, 0.1, 0.25, 1); 
            transition: opacity 1200ms cubic-bezier(0.25, 0.1, 0.25, 1);
       -moz-transition: none /* Removed until FF4 hang bug is fixed */
