뭐가틀렸는지 모르겠는데 버튼클릭시에 리스트가 뜨질않아요
제가 뭘놓친걸까요ㅜㅜ
html파일에는
<body>
<div class="container">
<nav class="navbar navbar-light bg-light">
<div class="container-fluid">
<span class="navbar-brand">Navbar</span>
<button class="navbar-toggler" type="button">
<span class="navbar-toggler-icon"></span>
</button>
</div>
</nav>
<ul class="list-group">
<li class="list-group-item">An item
<li class="list-group-item">A second item
<li class="list-group-item">A third item
<li class="list-group-item">A fourth item
<li class="list-group-item">And a fifth one
</div>
<script src="bootstrap/bootstrap.bundle.min.js">
document.getElementsByClassName('navbar-toggler')[0].addEventListener('click', function(){
document.getElementsByClassName('list-group')[0].classList.add('show')
})
</script>
</body>
css파일엔
.list-group{
display: none;
}
.show{
display: block;
}
