试图将我的Nav Bar和Hamburger图标集中

Question

因此，基本上我有一个向左漂浮的导航栏。该页面响应迅速，因此当屏幕低于一定尺寸时，导航栏消失(主页链接除外(，而汉堡包下拉菜单则弹出。我要做的是弄清楚如何使导航栏居中，并在屏幕尺寸减小并让汉堡图标出现并在屏幕上完全消失。

html：

<div class="topnav" id="myTopnav">  
<nav>
  <a href="home.html">Home</a>  
  <a href="history.html">History</a>  
  <a href="information.html">Information</a>  
  <a href="gallery.html">Gallery</a>
  <a href="videos.html">Videos</a>
  <a href="exercises.html">Exercises</a>
  <a href="contact.html">Contact</a> 
  <a href="links.html">Links</a>  
  <a href="javascript:void(0);" class="icon" onclick="myFunction()">&#9776;</a>
</nav>
</div>

CSS：

/* Add a black background color to the top navigation */
.topnav {
background-color: #000000;
overflow: hidden;
}
/* Style the links inside the navigation bar */
.topnav a {
float: left;
display: block;
color: #FFFFFF;
text-align: center;
padding: 14px 16px;
text-decoration: none;
font-size: 2.25em;
margin-bottom: 1.25%; 
}
/* Change the color of links on hover */
.topnav a:hover {
background-color: #2C3539;
color: #FFFFFF;
}
/* Add an active class to highlight the current page */
.active {
background-color: #4CAF50;
color: white;
}
/* Hide the link that should open and close the topnav on small screens */
.topnav .icon {
display: none;
}
/* When the screen is less than 600 pixels wide, hide all links, except for 
the first one ("Home"). Show the link that contains should open and close 
the topnav (.icon) */
@media screen and (max-width: 600px) {
.topnav a:not(:first-child) {display: none;}
.topnav a.icon {
float: right;
display: block;
}
}
/* The "responsive" class is added to the topnav with JavaScript when the 
user clicks on the icon. This class makes the topnav look good on small 
screens (display the links vertically instead of horizontally) */
@media screen and (max-width: 600px) {
.topnav.responsive {position: relative;}
.topnav.responsive a.icon {
position: absolute;
right: 0;
top: 0;
}
.topnav.responsive a {
float: none;
display: block;
text-align: left;
}
}

javaScript：

<script>
/* Toggle between adding and removing the "responsive" class to topnav when 
the user clicks on the icon */
function myFunction() {
var x = document.getElementById("myTopnav");
if (x.className === "topnav") {
    x.className += " responsive";
} else {
    x.className = "topnav";
}
}
</script>

这样做的任何帮助将不胜感激！

卸下浮子并显示：块，使用内联块可能会解决您的问题

display: inline-block;

您的新代码：

/* Add a black background color to the top navigation */
.topnav {
background-color: #000000;
overflow: hidden;
}
/* Style the links inside the navigation bar */
.topnav a {
display: inline-block;
color: #FFFFFF;
text-align: center;
padding: 14px 16px;
text-decoration: none;
font-size: 2.25em;
margin-bottom: 1.25%; 
}
/* Change the color of links on hover */
.topnav a:hover {
background-color: #2C3539;
color: #FFFFFF;
}
