I'm attempting to create a background with 85% height and 100% width on the index page using Bootstrap 4. However, when I set an image as the background in a div, it doesn't resize correctly and only shows a portion of the image (as the image is too large). When I tried using the img property, my navbar ended up moving below the image. I've searched online and tried various solutions, but nothing seems to work. Here's my code:
<!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>Restaurant</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="#">Restaurant</a>
<!-- Links -->
<div class="collapse navbar-collapse mright" id="nav-content">
<ul class="navbar-nav ml-auto">
<li class="nav-item active ">

</ul>
