Saya cuba membina tapak web sushi tetapi imej bahagian utama saya terus bergetar apabila menatal ke bawah dalam desktop skrin penuh. Navbar saya juga tidak berfungsi dalam versi mudah alih apabila menatal ke bawah, navbar tidak runtuh lebih kecil seperti yang berlaku dalam desktop. Saya juga mempunyai masalah dengan animasi tidak dimuatkan pada kali pertama saya melawat tapak.
