在以下代码中，如果我将checkbox放在nav之后，我就看不到<body>
<!-- If I remove nav completely, I see the checkbox, else I do not -->
<nav class="navbar navbar-expand-lg navbar-light bg-light fixed-top">
<a class="navbar-brand" href="#">Navbar </a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
</nav>
<input type="checkbox" id="ossm" name="ossm">
<label for="ossm">CSS is Awesome</label>
<script src="bower_components/jquery/dist/jquery.min.js"></script>
<script src="bower_components/popper.js/dist/umd/popper.min.js"></script>
<script src="bower_components/bootstrap/dist/js/bootstrap.min.js"></script>
</body>
。为什么呢？
