IE7 中的错误 - body -direction:rtl

Question

当我在 IE7 中将 body 元素方向设置为 rtl（IE8 中的兼容性视图）并将鼠标悬停在 ul li 上时，它奇怪地向左移动了几英寸。一个很好的例子是默认的 ASP.NET MVC CSS（将 direction:rtl 添加到 body 元素之后）。这里发生了什么？

示例代码：

/*----------------------------------------------------------

to use a different color start by replacing all instances of
#5c87b2 with your new color.

我在所有版本的 IE 中都看到过很多 RTL 页面问题。推荐的做法是在 HTML 标记上设置 RTL 方向，而不是使用 CSS 方向属性。

<html dir="rtl">

值得一开始就尝试一下，看看行为是否会发生变化。还确保页面以标准模式呈现，以便您获得整体上更一致的结果。
