html - 在兼容模式下尝试将鼠标悬停在 IE 8 上时 CSS 菜单消失

Question

我用 CSS 创建了一个下拉菜单，它在 Firefox、Chrome 和 IE8 中运行良好，但在 IE8 兼容模式下会失败。当您尝试将鼠标悬停在下拉菜单上时，它会消失。您可以在以下位置查看此问题:http://chocolat.digitaldementia.ca/chocolat .在过去的 4 天里，我一直在努力寻找解决此问题的方法，但到目前为止都没有成功。

CSS 代码如下所示:

#nav {
    padding: 0;
    margin: 0;
    list-style: none;
    height: 41px;
    /*background: url(images/menuitembackground.jpg) repeat-x;*/
    position: relative;
    z-index: 500;
    font-family: arial, verdana, sans-serif;
}

#nav li.top {
    display: block;
    float: left;
    height: 41px;
}

#nav li a.top_link {
    display: block;
    float: left;
    height: 40px;
    line-height: 34px;
    color: #ffe09a;
    text-decoration: none;
    font-size: 13px;
    font-weight: bold;
    padding: 0 0 0 15px;
    cursor: pointer;
    /*background: url(images/menuitembackground.png) no-repeat;*/
}

#nav li a.top_link span {
    float: left;
    display: block;
    padding: 0 24px 0 12px;
    height: 40px;
    /*background: url(three_0.gif) right top no-repeat;*/
}

#nav li a.top_link span.down {
    float: left;
    display: block;
    padding: 0 24px 0 12px;
    height: 40px;
   /* background: url(images/menuitembackground.png) no-repeat right top;*/
}

#nav li:hover a.top_link {
    color: #fff;
    background: url(images/menuitembackground.png) no-repeat left top;
}

#nav li:hover a.top_link span {
    background: url(images/menuitembackgroundright.png) no-repeat right top;
}

#nav li:hover a.top_link span.down {
    background: url(images/menuitembackgroundright.png) no-repeat right top;
}

/* Default list styling */
#nav li:hover {
    position: relative;
    z-index: 200;
}

#nav li:hover ul.sub {
    left: 1px;
    top: 40px;

    position: relative;
 margin: 0;

#nav li:hover li:hover ul, #nav li:hover li:hover li:hover ul, #nav li:hover li:hover li:hover li:hover ul, #nav li:hover li:hover li:hover li:hover li:hover ul {

HTML 是典型的列表结构:

<div id="menucontainer">
    <div id="menuList">
        <ul id="nav">
            <li class="top"> <a href="#" class="top_link"><span class="down">Welcome</span></a> 
            </li>
            <li class="top"> <a href="#" id="products" class="top_link"><span class="down">Treats</span></a> 
                <ul class="sub">
                    <li> <a href="#">Chocolates</a> 
                    </li>
                    <li> <a href="#">Coffees</a> 
                    </li>
                    <li> <a href="#">Baked Goods</a> 
                    </li>
                    <li> <a href="#">Gelato</a> 
                    </li>
                    <li> <a href="#">Light Menu Items</a> 
                    </li>
                </ul>
            </li>
            <li class="top"> <a href="#" id="locations" class="top_link"><span class="down">Locations</span></a> 
                <ul class="sub">
                    <li> <a href="#">3rd Avenue Cafe</a> 
                    </li>
                    <li> <a href="#">Massey Drive Cafe</a> 
                    </li>
                    <li> <a href="#">Mobile Cafe</a> 
                    </li>
                </ul>
            </li>
            <li class="top"> <a href="#" class="top_link"><span class="down">About</span></a> 
            </li>
            <li class="top"> <a href="#" class="top_link"><span class="down">Contact</span></a> 
            </li>
        </ul>
    </div>
</div>
