(.Net 2005) 'Filter' is not a known CSS property name.?

Question

I am using a CSS for a project that I am developing. I acquired the CSS from another source and I am getting an error on the 'filter' property. What is the CSS property for filter in 2005?

filter: progid:DXImageTransform.Microsoft.Gradient(GradientType=0, StartColorStr=#DCDFE5, EndColorStr=#BDC2CB);

That is the piece that I have.

Thanks

"filter" is not a valid CSS property. It is a proprietary CSS extension that only Microsoft IE recognizes. Visual Studio is designed to adhere to standards (thankfully) and does not like IE-only extensions to any W3C standard.

However, you should not have any problem compiling or publishing - VS will not stop either of those for a client-side syntax error. If you have all of your server-side code correct, it will publish regardless of HTML or CSS errors.
