내가 가진 이 자바 스크립트 파일 :

// .scroll to anchors 
jQuery(".scroll").on('click', function(e){
    e.preventDefault();
    var href = jQuery(this).attr('href');
    var hash = href.split('#');
    var url_hash = '#' + hash[1];
    if (jQuery(url_hash).length > 0) {
        var offset = (jQuery(window).width()<769) ? 20 : 65;
        jQuery('html, body').animate({
            scrollTop: jQuery(url_hash).offset().top-offset
        }, 1000);
    } else{
        location.href = href;
    }
});
