Not really. The unit identifier can only be omitted if the value is a <length> http://www.w3.org/TR/CSS21/syndata.html#length-units [quote] After a zero length, the unit identifier is optional. [/quote] or CSS3 values (editor draft): http://dev.w3.org/csswg/css3-values/#ltlengthgt If '0' is an e.g. an <angle>, the unit identifier is requried. In case of your gradients example, we're talking about a <color-stop>, which is basically a <length> http://dev.w3.org/csswg/css3-images/#color-stop-syntax so you can omit it, I think.
