Question

我正在尝试制作背景，85％高度和100％宽度索引页面。实际上我正在使用bootstrap 4.我的问题是，当我将图像作为背景放入div时，它不会调整大小只显示图像的一部分（图像太大）当我尝试使用img属性但我的导航栏跳转到图像下。当然，我尝试了互联网上的一切。这是我的代码。

<!DOCTYPE html>
<html lang="sk">

<head>

<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<link rel="stylesheet" type="text/css" href="styles/normalize.css">
<link rel="stylesheet" href="styles/b4.css">
<link rel="stylesheet" type="text/css" href="styles/style.css">
<title>Reštaurácia</title>    

</head>

<body>

 <!-- Navigation -->
<div class="bg">

<nav class="navbar navbar-expand-sm navbar-light bg-faded">
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#nav-content" aria-controls="nav-content" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>

<!-- Brand -->
<a class="navbar-brand mleft" href="#">Reštaurácia</a>

<!-- Links -->
<div class="collapse navbar-collapse mright" id="nav-content">
