Nope, that's exactly how it should be — when the gradients were unprefixed, the w3c changed the syntax, see [this article](http://blogs.msdn.com/b/ie/archive/2012/06/25/unprefixed-css3-gradients-in-ie10.aspx), for example:

> 0deg is a gradient line pointing to the top. Angles increase in a clockwise direction. Old angles can be converted to new angles using the formula `new = abs(old−450) mod 360`
