我想让图像垂直居中，类似于文本按钮，与它们在同一条线上。我已经尝试过不同的对齐等等，但没有成功。我假设有一种方法可以去做，而不必使用与文本不同的方法。

This就是它在实践中的样子。

Answer 1

您可以使用flexbox和属性align-items: center垂直居中菜单内容。

如果使用flexbox，您将不需要使用float。要从徽标中分隔菜单项，请将margin-right: auto添加到徽标中。

我已经简化了下面演示的代码，并删除了一些错误。（.topnav宽度和高度需要单位，过渡＆＃39;文字＆＃39;不是属性）

＆＃13;

.topnav {
  position: sticky;
  font-family: 'Roboto', sans-serif;
  background-color: black;
  color: white;
  
  /*padding: 0 15%;*/
  display: flex;
  align-items: center;
}

.logo {
  margin-right: auto;
}

.topnav a {
  transition: color 0.15s ease-in-out;
  color: #f2f2f2;
  padding: 18px;
  text-decoration: none;
  font-size: 10px;
}

.topnav a:hover {
  color: #977DA0;
}

.topnav a.active {
  color: white;
}

＆＃13;

<div class="topnav">
  <a class="logo" href=""><img src="https://unsplash.it/20" alt="51 Pegasi logo"></a>
  <a class="active" href="#home">HOME</a>
  <a href="#about">ABOUT</a>
  <a href="#gamedesign">GAME DESIGN</a>
  <a href="#gamedev">GAME DEV</a>
  <a href="#programming">PROGRAMMING</a>
  <a href="#music">MUSIC</a>
</div>

＆＃13;

Answer 2

您可以使用CSS flexbox垂直居中徽标＆amp;菜单。

.topnav{ display: flex; flex-direction: row; align-items: center; justify-content: space-between; } .navigation{ text-align: right; } .navigation ul{ margin: 0; list-style: none; } .navigation ul li{ display: inline-block; }

<div class="topnav"> <div class="logo"> <a href="#"><img src="http://lorempicsum.com/futurama/50/50/1" alt="logo"></a> </div> <div class="navigation"> <ul> <li><a href="#">Menu 1</a></li> <li><a href="#">Menu 2</a></li> <li><a href="#">Menu 3</a></li> <li><a href="#">Menu 4</a></li> <li><a href="#">Menu 5</a></li> </ul> </div> </div>

Answer 3

您可以通过在display: flex类上添加.topnav并删除图片代码上的15％宽度和高度来实现此目的。最后在align-items: center;类上添加.topnav以垂直居中图像。

Answer 4

你也可以考虑＆＃34; Bootstrap4＆＃34;它为您的样式提供了出色的浏览器支持。使用BS4，您只需要在HTML中添加相应的类，它就可以在大多数浏览器中正常运行而不会出现问题。您的代码可能如下所示：

＆＃13;

<!doctype html>
<html lang="en" style="overflow: hidden">
	<head>
