//This JavaScript code can be added into Divi using the integration option at: > Theme Options > Integration >"Add code to the < head > of your blog", and as a result will survive theme updates. 

<script>
document.addEventListener('DOMContentLoaded', function(event){ 

    if (window.location.hash) {
        // Start at top of page
        window.scrollTo(0, 0);
		
        // Prevent default scroll to anchor by hiding the target element
        var db_hash_elem = document.getElementById(window.location.hash.substring(1));
        window.db_location_hash_style = db_hash_elem.style.display;
        db_hash_elem.style.display = 'none';
		
        // After a short delay, display the element and scroll to it
        jQuery(function($){
            setTimeout(function(){
                $(window.location.hash).css('display', window.db_location_hash_style);
                et_pb_smooth_scroll($(window.location.hash), false, 800);
            }, 700);
        });		
    }
});
