我在这里有一个导航栏的代码。当我将鼠标悬停在链接上时,一个 png 图像的小箭头应显示在其下方的中心。下面的代码在 Firefox 和 Chrome 中运行良好,但在 IE 中,箭头略低于 div,因此只能看到其中的一部分。有什么问题?
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="style.css">
<link rel="stylesheet" type="text/css" href="normalize.css">
</head>
<body>
<div id="wrapper">
<div id="logo-wrapper">
<a href="#"><img src="logo.png" id="logo"></a>
</div>
<div id="menu-wrapper">
<ul>
<li><a id="home" href="#" >Home</a></li>
<li><a href="#" >Work</a></li>
<li><a href="#" >Us</a></li>
<li><a href="#" >Contact</a></li>
</ul>
</div>
</div>
