我创建了一个网站，并尝试进行响应式设计。我在youtube上关注视频，并按照视频中的内容做任何事情，但我没有看到汉堡图标。你知道为什么吗？它在视频中效果很好。以下是我的代码：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Nikolinart</title>
<link rel="stylesheet" href="./styles/style.css">
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
</head>
<body>
<nav class="navbar">
<div class="max-width">
<div class="logo"><a href="#">Nikolin<span>art</span></a></div>
<ul class="menu">
<li><a href="#">Home</a></li>
<li><a href="#">About</a></li>
<li><a href="#">Gallery</a></li>
<li><a href="#">Contact</a></li>
</ul>
<div class="menu-btn">
<i class="fas fa-bars"></i>
</div>
</div>
</nav>
<section class="home" id="home">
<div class="max-width">
<div class="home-content">
<div class="text-1">Hello and welcome to</div>
<div class="text-2">Nikolin<span>art</span></div>
<div class="text-3">My name is Nikolina and I'm a <span>Painter</span></div>
</div>
</div>
</section>

.menu-btn {
color: #fff;
font-size: 23px;
cursor: pointer;
display: none;
}
两个可能的原因：
您设置了使文本隐藏的display:none，或者您意外使用了color:#fff(白色(并与background具有相同的颜色
此外，你甚至没有它的内容。
.menu-btn {
color:red;
font-size: 23px;
cursor: pointer;
}<div class="menu-btn">
<i class="fas fa-bars">Yes</i>
</div>display：none隐藏元素你需要删除那行css
在CSS属性中，display属性为None，用于隐藏元素。将类更改为
.menu-btn {
color: #fff;
font-size: 23px;
cursor: pointer;
}
此外，我看到你使用了字体真棒图标，但你没有导入它们，请确保正确导入它们。如果您使用CDN加载Font Awesome，请确保在HTML的HEAD标记中添加必要的导入。
