它无法正常工作，因为下面的东西被移动了。帮助

Answer 1

#editor-bold:hover #editor-tags {
    display: inline-block;
}

#editor-tags 不是#editor-bold的后代。

通常情况下，就是这样......

HTML

<ul>
    <li><h5>About</h5>
        <ul>
            <li>a</li>
            <li>b</li>
            <li>c</li>
        </ul>
    </li>
</ul>

CSS

ul li ul {
    display: none;
}

ul li:hover ul {
    display: block;
}

要么是这样，要么使用JavaScript来实现它并保留HTML（尽管禁用JavaScript的用户可能会发现您的应用程序难以使用）。

更新

你可以使用jQuery ...

$('#editor-bold').hover(function() { $('#editor-tags').show(); }, function() { $('#editor-tags').hide(); });

使用css显示/隐藏div
