我發現這個非常簡單的方法來在w3schools上做出響應菜單(article),但我一直在努力嘗試水平居中。如何居中導航
HTML
<ul class="topnav">
<li><a href="#home">Home</a></li>
<li><a href="#news">News</a></li>
<li><a href="#contact">Contact</a></li>
<li><a href="#about">About</a></li>
<li class="icon">
<a href="javascript:void(0);" onclick="myFunction()">☰</a>
</li>
</ul>
CSS
/* Remove margins and padding from the list, and add a black background color */
ul.topnav {
list-style-type: none;
margin: 0;
padding: 0;
overflow: hidden;
background-color: #333;
}
/* Float the list items side by side */
ul.topnav li {float: left;}
/* Style the links inside the list items */
ul.topnav li a {
display: inline-block;
color: #f2f2f2;
text-align: center;
padding: 14px 16px;
text-decoration: none;
transition: 0.3s;
font-size: 17px;
}
/* Change background color of links on hover */
ul.topnav li a:hover {background-color: #111;}
/* Hide the list item that contains the link that should open and close the topnav on small screens */
ul.topnav li.icon {display: none;}
