Answer 1

将此ul#menu li :hover ul.sub-menu更改为ul#menu li:hover ul.sub-menu。这是我假设您的HTML可能如下所示的唯一问题。

<ul id="menu">
    <li>
      <a href="#">menu1</a>
    </li>
    <li>
      <a href="#">menu2</a>
      <ul class="sub-menu">
        <li>
          <a href="#">submenu1</a>
          <a href="#">submenu2</a>
          <a href="#">submenu3</a>
          <a href="#">submenu4</a>
        </li>
      </ul>
    </li>
  </ul>
