Microsoft Drops Support For CSS Expressions

No "Dynamic Styles" anymore starting with IE8 in Standards mode

[poppyrich]

CSS expressions are being phased out.

This from the IE8 release notes:

"CSS Expressions is no longer supported in Internet Explorer 8 Standards mode
CSS Expressions is a proprietary extension to CSS that has a high performance cost. (CSS Expressions is also known as "Dynamic Properties.") Starting with Internet Explorer 8 Beta 2, CSS Expressions is no longer supported in Internet Explorer 8 Standards mode. CSS Expressions is still supported in Internet Explorer 7 Strict mode and Quirks mode for backward compatibility.

Ok, partial success, pity they didn't get rid of it completely (as well as that useless IE7 mode).
