私は初めてブートストラップを扱っています。私が何をしていても、ハンバーガーメニューが正しく表示されません。ここに私のコードは次のとおりです。

<div class="container-fluid">

    <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navnavnav">

    <a class="navbar-brand" href="#"> 
 
     <img src="http://image.jpg" width="60" height="52" class="d-inline-block align-top" alt="logo"> 
 
    </a> 
 
    <div class="collapse navbar-collapse" id="navnavnav"> 
 
    <ul class="nav navbar-nav" style="font-size: 1.5em">
