html - 悬停前子菜单可见加子菜单背景使用父悬停背景

Question

我希望我能对此有一些新的看法。我知道我在这里的某个地方犯了一个菜鸟编码错误，但我似乎无法找到它，而且我的眼睛正在斗鸡眼。请帮忙。

因此，子菜单甚至在悬停之前就保持可见，并且由于某种原因，每个子菜单项的背景都采用了父悬停背景属性，我终究无法弄清楚原因。

我做了Fiddle

HTML

<div id="menu">
    <ul>
        <li class="current_page_item"><a href="home.html">Home</a></li>
        <li><a href="#">About</a></li>
        <li><a href="#">Services</a>
        <ul>
        <li class="style13"><a href="#"><strong>Option 1</strong></a></li>
        <li class="style13"><a href="#"><strong>Option 2</strong></a></li>
        </ul></li>
        <li><a href="#">Comments</a></li>
        <li><a href="#">Contact</a></li>
    </ul>

</div>

Answer 1

该 CSS 实际上并没有隐藏或显示子菜单。尝试添加这个:

#menu ul ul {
    display: none;
}
#menu li:hover ul{
    display: block;
}
