javascript - 想要在鼠标悬停子菜单上保持菜单黑色的字体颜色

Question

我正在使用 superfish 菜单，我想在将鼠标移到子菜单上时保持父菜单的颜色为黑色。目前，当我将鼠标移到子菜单上时，父菜单颜色变为与背景相同的白色。但是我希望字体颜色为黑色而不是白色。我怎样才能实现它。请帮我。提前致谢。

这是我的 html 代码:

<div id="mainmenu">
  <ul class="sf-menu">
    <li><a href="#"><span>Home</span></a></li>
    <li><a href="#"><span>About Us</span></a>
      <ul>
        <li><a href="#"><span>About 1</span></a></li>
        <li><a href="#"><span>About 2</span></a></li>
      </ul>
    </li>
    <li><a href="#"><span>Portfolio</span></a>
      <ul>
        <li><a href="#"><span>All Projects</span></a></li>
        <li><a href="#"><span>Single Type #1</span></a></li>
        <li><a href="#"><span>Single Type #2</span></a></li>
      </ul>
    </li>
    <li><a href="#"><span>Services</span></a>
      <ul>
        <li><a href="#"><span>Services 1</span></a></li>
        <li><a href="#"><span>Services 2</span></a></li>
      </ul>
    </li>
    <li><a href="#"><span>News</span></a></li>
    <li><a href="#"><span>Contact</span></a></li>
  </ul>
</div>

您需要在悬停后包含 anchor 。

我在你的代码部分旁边评论过，在这个 css .sf-menu li:hover a 之后，
.sf-menu li.sfHover a {}

body {background: grey;}
