javascript - 为什么我的网站无法在 Iphone 上正确加载？

Question

我在这个领域很新，我正在学习前端开发，这是我的第二个元素，我不知道这是什么问题。

我最近创建了 this website :

   
    $(document).ready(function(){
        $('body').scrollspy({target:".navbar", offset: 50});
        $('nav a').smoothScroll({offset: -40});
    });

        body {
        position: relative,
    }
    body, html {
        height: 100%;
    }
    .div {
        display: block;
    }
    
    .navbar-inverse .navbar-nav>li>a {
        color: white;
    }
    
    .navbar {
        margin-bottom: 0px;
        font-size: 18px;
        box-shadow: 0 4px 8px 0 rgba(0, 0, 0, 0.2), 0 6px 20px 0 rgba(0, 0, 0, 0.19);
        
    }
    
    .navbar>.container .navbar-brand, .navbar>.container-fluid .navbar-brand {
        color: white;
        font-family: "Oleo Script", cursive;
        font-size: 25px;
    }
    
    i:hover {
        opacity: 0.4;
    }
    
    .bg { 
        position: relative;
        background-image: url("https://raw.githubusercontent.com/Arielink90/project/master/image/pexels-photo-261577.jpeg");

    </footer>

它在计算机和 Android 设备上加载正常，但在 iPhone 上加载不正常，我找不到原因。如果有人可以向我解释问题或给我任何想法，那将非常有帮助。谢谢。
