推荐答案

HTML组件，一种在网页上封装逻辑的方法。行为在 1999 w3 CSS工作草案中描述，但（据我所知）只有Microsoft在IE 5中提供了一个实现，今天有更好的方法来完成相同的任务。

It's an HTML Component, a means of encapsulating logic on a web page. Behaviors were described in a 1999 w3 CSS working draft but (as far as I know) only Microsoft provided an implementation in IE 5 and today there are better ways of accomplishing the same tasks.

HTC应仅用作后备机制（您的示例演示）。

HTCs should only be used as a fallback mechanism (which your example demonstrates). Most of what is possible with them is possible using standard, cross-browser CSS and JavaScript in IE 9 and higher.

对于为什么它可以使用标准的跨浏览器CSS和JavaScript在IE 9和更高版本。作品，我的猜测是，该行为操纵特定于IE的功能，如DHTML过滤器或 VML ，可用于实现视觉结果在他们的时间之前（虽然现在已经废弃）。

As to why it works, my guess is that the behavior manipulates IE-specific functionality such as DHTML filters or VML which can be used to achieve visual results that were ahead of their time (though now deprecated).
