Question

我在IE7中使用这个css代码，它运行良好，没有任何问题。现在在IE11和chrome下拉不起作用我看到主菜单和所有子菜单在一起。需要一个帮助，以了解可以采取哪些措施来解决它。感谢。

<div id='cssmenu'> 
  <ul>
    <li class='active'><a href='url'><span>text</span></a></li> 
    <li class='has-sub'><a href='#'><span>text</span></a></li> 
    <ul> 
      <li><a href='url'><span>text</span></a></li> 
      <li><a href='url'><span>text</span></a></li> 
    </ul>

我很惊讶HTML在预期的任何地方都能正常工作，但IE7却是一大堆bug。

您有<ul>作为另一个<ul>的孩子，这不是有效的HTML。 <ul>只能包含<li>个元素。该子菜单列表应该是其上方<li>的子：

<li class='has-sub'><a href='#'><span>text</span></a> 
  <ul> 
    <li><a href='url'><span>text</span></a></li> 
    <li><a href='url'><span>text</span></a></li> 
  </ul>
</li>
