我正在尝试将 CSS 精灵用于导航栏。经过大量的互联网研究，我想我已经确定了“最简单”的方法。除了单击浏览器的“后退”按钮外，一切似乎都可以正常工作。在 IE (8.0.6001.18701) 中，活动状态为“卡住”（看起来按钮被按下）。在 Firefox (14.0.1) 中，悬停状态为“卡住”。我可以忍受 Firefox 的问题，因为一旦鼠标从后退按钮移开，它就会消失，而不是 IE 的问题。我目前在头文件中有导航栏，我将其与 Includes 一起使用以保持简单和一致。这是模板html。我将它用于我的所有页面。（当我解决了这个问题时，我将实际进入其余的身体）
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<link rel="stylesheet" type="text/css" href="DS.css">
</head>
<body>
<div id="centerpage">
<table border="0" width="100%" cellspacing="0" cellpadding="0" id="table1">
<tr>
<td>
<!--webbot bot="Include" U-Include="Nav_Includes/Header.htm" TAG="BODY" --></td>
</tr>
<tr>
<td>Enter page data here.<br>
<hr width="770" size="1">
<span id="timestamp">Page last updated:
<!--webbot bot="Timestamp" S-Type="EDITED" S-Format="%m/%d/%Y %I:%M %p" --></span></td>
</tr>
<tr>
<td>
<!--webbot bot="Include" U-Include="Nav_Includes/Footer.htm" TAG="BODY" --></td>
</tr>
</table>
</div>
</body>
</html>
这是header.htm：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>Dolphin Storage Header</title>
<link rel="stylesheet" type="text/css" href="../DS.css">
</head>
<body>
<img border="0" src="../images/header.jpg" width="760" height="101" align="center">
<p><a class="navHome" href="../index.htm"></a>
<a class="navUnits" href="../units.htm"></a>
<a class="navSpecials" href="../specials.htm"></a>
<a class="navAbout" href="../about.htm"></a>
<a class="navContact" href="../contact.htm"></a></p>
</body>
</html>
该css文件：
