-ms-filter vs filter What's the difference?
提问by Web_Designer
What's the difference between between IE's filterand -ms-filterproperties? If I use one should I use them both? Do they do the same thing, but each work on only certain versions of IE?
IEfilter和-ms-filter属性之间有什么区别？如果我使用一个，我应该同时使用它们吗？他们做同样的事情，但每个人都只在某些版本的 IE 上工作吗？

Microsoft introduced -ms-filterto make Internet Explorer more standards-compliant (CSS 2.1 requires vendor extensions to have vendor prefix). As the syntax of original filterproperty is not CSS 2.1 compliant, IE8+ requires the value of the -ms-filterproperty to be enclosed in quotation marks.
Microsoft 引入-ms-filter以使 Internet Explorer 更符合标准（CSS 2.1 要求供应商扩展具有供应商前缀）。由于原始filter属性的语法不符合 CSS 2.1，IE8+ 要求将-ms-filter属性值括在引号中。
filter: alpha(opacity=40);
-ms-filter: "alpha(opacity=40)";
-ms-filteris supported in IE8+, legacy filterproperty is, as far as I know, for backwards compatibility supported in all versions of Internet Explorer.
-ms-filterIE8+ 支持filter，据我所知，遗留属性是为了在所有版本的 Internet Explorer 中支持向后兼容性。

Please note that support for filters may be removed in IE10.
请注意，IE10 中可能会删除对过滤器的支持。

-ms-filter property
Sets or retrieves the filter or collection of filters that are applied to the object. Note As of Windows Internet Explorer 9 this feature was deprecated. As of Internet Explorer 10 this feature was removed and should no longer be used.
-ms-filter 属性
设置或检索应用于对象的过滤器或过滤器集合。注意 从 Windows Internet Explorer 9 开始，此功能已被弃用。从 Internet Explorer 10 开始，此功能已被删除，不应再使用。

I believe -msis the vendor prefix for some of the new CSS3 properties while filteris an older property meant for IE 6-8(I could be wrong on IE 6, but I know for sure it's used in IE 8). Here's more information on where -msis used: http://msdn.microsoft.com/en-us/library/ms531207(VS.85).aspx.
我相信-ms是一些新 CSS3 属性的供应商前缀filter，而是用于 IE 6-8 的旧属性（我在 IE 6 上可能是错的，但我确定它在 IE 8 中使用）。以下是有关使用位置的更多信息-ms：http: //msdn.microsoft.com/en-us/library/ms531207(VS.85).aspx。
