Sorry to be less technical than in general but something painful just happened to me while working on the CSS editor of BlueGriffon and I wanted to share that with the CSS community...
BlueGriffon is based on the source of Firefox 4. The
property is then implemented unprefixed in the rendering engine.
Even if BlueGriffon outputs styles for other rendering engines (using
Peter Beverloo's excellent list and my JSCSSP parser/serializer), I considered that one version
(the last public one) of each rendering engine is enough.
And I just got a mail from a user complaining that
From a user's perspective (hear web author's perspective), this is a perfectly fine request. From my software implementor's point of view, it's a nightmare.
If CSS vendor prefixes are useful for standardization and implementation of experimental features, they're harmful to the users' community and painful to software management. Our current situation wrt vendor prefixes is still suboptimal, to say the least.
I am not going to support in BlueGriffon prefixed versions of properties that are now unprefixed in the last public version of browsers. Example: I don't plan to support the WebKit gradients forever...
