问题描述
我有以下导航其中.topNav有position：relative和subnav有position：absolute。我不能得到子列表出现在主列表由于z-index问题。这似乎是一个已知的问题。
I have the following navigation where .topNav has position:relative and subnav has position:absolute. I cant get the sublist to appear over the main list due to z-index problems. This seems to be a known problem.
<ul>
<li class="topNav">About Us
<ul class="subNav"><li> Subsection A</li><li>Subsection B</li></ul>
</li>
</ul>
有人知道解决方法吗？
更新显示了我所遇到的问题。我的原始发布是在列表的上下文中，但我已经减少了问题，z-index dosn't似乎工作，当一个元素与position：absolute在一个父元素的位置：relative
UPDATE http://brh.numbera.com/experiments/ie7_tests/zindex.html shows exacly the problem I have. My original posting was in the context of a list but I have reduced the problem to the fact that z-index dosn't seem to work when have an element with position:absolute inside a parent element with position:relative
推荐答案
这里有一篇很好的文章，解释了machineghost提到的堆叠问题。
Here's a very good article that explains the stacking issues that machineghost mentions.
您可能需要考虑什么（取决于您想要在多个元素上进行定位的原因） .base（使用JavaScript的IE6）添加类给它相对性。
What you might want to consider (depending on why you're wanting the positioning on multiple elements) is adding a hover selector to .base (use JavaScript for IE6) that adds the class to give it relativity.
.base:hover{position:relative;}
这意味着第二个.base没有position：relative。
This then means that the second .base doesn't have position: relative.
这篇关于IE z-index相对/列表中的绝对错误的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
