我对最新的IE有一个非常奇怪的渲染问题（不了解其他人）。
这是它在chrome（正确方式）中的外观：http://i.imgur.com/0xTakai.png
现在看看IE：http://i.imgur.com/2iptseA.png（忽视角落里的东西，不是问题）
但是这里有奇怪的部分，当我取消选中并重新检查开发工具margin:0;中的#cssmenu,
#cssmenu ul,
#cssmenu ul li,
#cssmenu ul li a {
margin: 0 !important;
padding: 0;

时，它正确格式化。 http://i.imgur.com/MPlFval.png
任何想法是什么导致它以及如何解决它？我想使用javascript作为最后的手段，尽可能避免使用它。
有点长，但这里是负责菜单的完整CSS：
<div id='cssmenu'>
<img src="img/sidelogo.png" width="50%" />
<ul>
<li class='active'><a href='index.html'><span>Home</span></a></li>
<li><a href='#' class="sb-close"><span>About</span></a></li>
<li class='has-sub'><a href='#'><span>Labs</span></a>
<ul>
<li class='has-sub'><a href='#'><span>Experiments</span></a>
<ul>
<li><a href='#' class="sb-close"><span>Exp 001</span></a></li>
<li class='last'><a href='#' class="sb-close"><span>Exp 002</span></a></li>
</ul>
</li>
<li class='has-sub'><a href='#' ><span>Projects</span></a>
<ul>
<li><a href='//knyz.org/design/Deep Space/' class="sb-close"><span>Deep Space</span></a></li>
<li><a href='//knyz.org/design/Deep Space Dark/' class="sb-close"><span>Deep Space Dark</span></a></li>
<li class='last'><a href='//mdd.knyz.org/' class="sb-close"><span>MDD</span></a></li>
</ul>
</li>
</ul>
</li>
<li><a href='docs' class="sb-close"><span>Documents</span></a></li>
<li><a href='#' class="sb-close"><span>Archives</span></a></li>
