我正在嘗試在 CSS 中創建導航欄的平滑影片，這是我的 HTML 代碼-
<body>
<nav class="navbar">
<ul class="nav-list another">
<li><n>Engine</n></li>
<li><a href="#home">Home</a></li>
<li><a href="#About">About</a></li>
<li><a href="#Contact Us">Contact Us</a></li>
<li><button type="button" id="mysearch">More</button></li>
</ul>
</nav>
<hr>
</body>
</html>
這是我的 CSS 代碼-
*{
margin: 0;
padding: 0;
}
html{
background-color: white;
background-image: url("img/ManHattanImage.webp");
}
li{
align-items: left;
width: 100px;
height: 100%;
display: inline-block;
margin-right: 170px;
font-size: 20px;
/* background-color: black; */
color: black;
font-size: 20px;
}
hr{
color: black;
margin-top: 30px;
}
n{
/* background-color: black; */
color: white;
font-size: 40px;
font-style: bold;
font-family: "Lucida Console", "Courier New", monospace;
margin-left: 20px;
margin-top: 30px;
}
a {
text-decoration: none;
color: white;
}
a:visited { text-decoration: none; }
a:hover {
text-decoration: none;
/* background-color: black; */
}
a:focus { text-decoration: none; }
a:hover, a:active { text-decoration: none; }
nav:hover{
height:300px;
}
我想要一個干凈的影片，比如一個好的下拉選單導航欄，并且有明顯的重疊，我也可以在導航欄內添加更多元素（進一步更新）？

這是制作下拉選單的方法，但我不確定如何制作影片。我希望這就是您所說的下拉選單。
