Remove/reset CSS behavior property
提问by Jeremy Kauffman
Is it possible to remove the IE-specific behavior CSS property via a more specific rule or the !importantdeclaration? Example:
是否可以通过更具体的规则或!important声明删除特定于 IE 的行为 CSS 属性？例子：
.a-rule
{
behavior: url(/some.htc);
}
.a-rule.more-specific
{
behavior: /*no HTC*/
}
I realize that overriding CSS properties is undesirable, but I'm stuck here.
我意识到覆盖 CSS 属性是不可取的，但我被困在这里。
On Edit: I'm not sure where people are getting confused about this question. For all purposes, you can consider this already being an IE specific stylesheet. I'm asking how, if .a-ruleabove exists and is immutable, how can one remove the behavior via a more specific rule? A standard CSS equivalent would be:
关于编辑：我不确定人们在哪里对这个问题感到困惑。出于所有目的，您可以认为这已经是 IE 特定的样式表。我在问如何，如果.a-rule上述存在并且是不可变的，如何通过更具体的规则删除行为？标准的 CSS 等效项是：
.a-rule
{
border: 1px solid black;
}
.a-rule.more-specific
{
border: 0 none;
}
One can reset the border property for a subset of elements via a more specific rule. I'm asking how to reset the behavior property in an analogous way.
可以通过更具体的规则重置元素子集的边框属性。我在问如何以类似的方式重置行为属性。

The default value is "none". See:

.a_rule {
border: 1px solid black; /* we know border is black */
behavior: url(/some.htc) /* we know something happen inside some.htc */
}
.a_rule.more-specific {
border: 0 none; /* we remove the border */
behavior: url(/some.htc) /* we remove something inside some.htc */
}
use different .htcfile
使用不同的.htc文件

Maybe use conditional tags for IE in your head
也许在你的脑海中为 IE 使用条件标签
<!--[if IE]>
<style type="text/css">
.a-rule {
behavior: url(/some.htc);
}
</style>
<![endif]-->
