Script Tombol kembali keatas - UP CSS3 dan jQuery

Script Tombol UP ini sering digunakan oleh para blogger dan situs-situs besar. Gunanya untuk mempermudah Pengunjung untuk kembali ke atas. Sebenarnya menurut saya ini jarang sekali dipakai cuman hanya untuk hiasan blog. Tetapi apabila konten Artikel di blog anda sangat panjang mungkin tombol ini berguna bagi pengunjung.

<a href="#0" class="back-to-top cd-top"><span class="fa fa-chevron-up"></span> <span>Kembali ke atas</span></a><script>
$(window).scroll(function() {
       ($(this).scrollTop() > ($('header').height() + 200)) ? $('.back-to-top').addClass('cd-is-visible') : $('.back-to-top').removeClass('cd-is-visible cd-fade-out');
       }).trigger('scroll');
       $(window).resize(function() {
       var right = (($(window).width() - $('section').width())/2)+95;
       if ($('nav.sidebar').hasClass('affix')) {
       $('nav.sidebar').css('right', right+'px');
       }
       }).trigger('resize');
       $('.back-to-top').on('click', function(event) {
       event.preventDefault();
       $('html,body').animate({
       scrollTop: 0
       }, 700);
       });
