Question

当用户向下滚动以覆盖页面顶部的导航栏和文本时，我希望屏幕底部的图像向上滚动，这应保持文具。

这可以在css中完成，还是必须使用jQuery？

HTML：

<head>
    <link rel="stylesheet" type="text/css" href="css/style.css">
    <link href='http://fonts.googleapis.com/css?family=Alegreya+Sans:300,400,800' rel='stylesheet' type='text/css'>
</head>
<body>
    <div class="header">
        <div class="col-25">
            <img id="logo" src="images/logo-black.svg">
        </div>
        <div class= "col-50">
            <ul class="main-nav">
                <li class="main-nav-link">
