IE 的 CSS 样式菜单问题

我对html CSS响应式菜单和Internet Explorer有一个奇怪的问题。如果我在IE浏览器中看到菜单的html，那么在IE和Firefox中似乎一切都很好，颜色正确，但是如果我在我的 ASP.NET 网站中插入相同的html页面，并且我使用本地Visual Studio实例通过Internet Explorer，我看到菜单的颜色不是红色，而是蓝色！我只使用菜单的样式。

这是菜单演示页面的 HTML：

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="initial-scale=1, maximum-scale=1" />
    <title>Demo menu</title>
    <style type="text/css">
        body {
            font-family: Helvetica, Arial, sans-serif;
            font-size: 13px
        }
    </style>
    <link type="text/css" rel="stylesheet" href="js-css-menu.css" media="screen" />
</head>
<body>
    <p><b>Responsive CSS3 Menu with Dropdown (Horizontal and Vertical)</b></p>
    <ul class="js-css-menu shadow responsive">
        <li><a href="#">Link</a></li>
        <li class="current"><a href="#">Current</a></li>
        <li><a href="#">Link with Menu</a>
            <div>
                <ul>
                    <li><b>Col 1</b></li>
                    <li><a href="#">Sublink 1</a></li>
                    <li><a href="#">Sublink 2</a></li>
                    <li><a href="#">Sublink 3</a></li>
                </ul>
                <ul>
                    <li><b>Col 2</b></li>
                    <li><a href="#">Sublink 1</a></li>
                    <li><a href="#">Sublink 2</a></li>
                    <li><a href="#">Sublink 3</a></li>
                </ul>
            </div>
        </li>
        <li><a href="#">Link</a>
    </ul>
</body>
</html>

使用此 CSS 样式：

您尚未设置标准的 CSS 链接颜色，因此将其设置为通用蓝色。

将其添加到您的 CSS 中，其中包含您希望链接的任何颜色：

a:link {color: #FF0000; text-decoration: none;}
a:hover {color: #FF0000;text-decoration: none;}
a:active {color: #FF0000;text-decoration: none;}
a:visited {color: #FF0000; text-decoration: none;}

HTML代码中有一个未闭合的括号。
