dynamic-shadow.js

// To add the text dynamically, use a class (overlay-title) in the h2 to catch the object and modify h2::before for "overlay-title-shadow"
(function( $ ) {
	'use strict';

	 // Window loaded
	 $(window).on("load",function(){
		 const postTitleObj = $( '.overlay-title h2' );
         if( 0 < postTitleObj.length ) {     
            postTitleObj.before( '<div class="overlay-title-shadow">' + postTitleObj.html() + '</div>' );
         }
