中心徽标div与用于导航的浮动

Question

我在尝试使徽标与导航链接正确对齐时遇到困难。我想到的解决方案是为徽标div添加填充和边距，但这仍然不起作用。 我一直在试图找到解决这个问题的方法，但无济于事。有关如何解决此问题的任何帮助将不胜感激。非常感谢！

法典：

function myFunction() {
    var x = document.getElementById("myTopnav");
    if (x.className === "topnav") {
        x.className += " responsive";
    } else {
        x.className = "topnav";
    }
}

您需要包装左部分、中心部分和右部分，而不是使用 flex，您可以获得所需的结果。

你的 HTML 会是这样的

<div class="topnav" id="myTopnav">
  <!-- Left Portion -->
  <div>
    <a href="#home" class="active right">Home</a>
  <a href="#news" class="right">News</a>
  <a href="#contact" class="right">Contact</a>
  <div class="dropdown right">
    <button class="dropbtn">Dropdown 
      <i class="fa fa-caret-down"></i>
    </button>
    <div class="dropdown-content">
      <a href="#">Link 1</a>
      <a href="#">Link 2</a>
      <a href="#">Link 3</a>
    </div>
  </div> 
  </div>
<!-- Center Portion -->
<div class="center">
  <div class="logo">
    <a href="">My Logo here</a>
  </div>
</div>

<!-- Right Portion -->
<div>
  <a href="#about" class="left">About</a>
  <a href="#about" class="left">About</a>
  <div class="dropdown left">
    <button class="dropbtn">Dropdown 
      <i class="fa fa-caret-down"></i>
    </button>
    <div class="dropdown-content">
      <a href="#">Link 1</a>
      <a href="#">Link 2</a>
      <a href="#">Link 3</a>
    </div>
  </div> 
</div>

  <a href="javascript:void(0);" style="font-size:15px;" class="icon" onclick="myFunction()">&#9776;</a>
</div> 

修改 .topnav 类的 css

.topnav {
   overflow: hidden;
  background-color: #333;
  display: flex;
  justify-content: space-between;
  align-items: center;
 }
