IE很讨厌我的CSS文件，所以我没有内容！

Question

我的网站似乎与其他所有更加漂亮但IE8，IE9和兼容模式一样正常工作!!

一旦我禁用我的CSS，我就会看到内容，但是当它重新打开时，我什么都没得到！

这是我的地狱。

这是我的CSS：

    body {
        background: center top url(./images/background.jpg) no-repeat;
        background-color: #FFF;
        margin: 0px;

    body,td,th {

Answer 1

如何确定错误：

1. 从样式表中删除所有类。
2. 逐个添加课程。
3. 查看失败的时间/地点
4. 修复/解决错误
5. 如果不是最后，请继续执行第2步

Answer 2

    #panel {
        width: 100%;
        height: 280px;
        color: #333;
        background: transparent url(images/tab_bk.png) repeat;
        overflow: hidden;
        position: relative;
        z-index: 3;
        display: none;
    }

虽然DIV实际上已关闭，但出于某种原因，IE完全忽略了它！ 这就是问题所在：

        display: none;

所以我所做的就是将DIV放在页脚中。它仍然让我感到困惑，为什么它只是在IE中做它!!
