With this, you're setting a very narrow (yet at the same time very wooly) set of criteria. You're suggesting that presentational aspects of default UA styling are, at least in part, "accessibility features", but don't actually pin down exactly which part of them. Then, you're suggesting authors may, essentially, only add/replace but never substract styles in order to "retain or enhance their effectiveness"? None of this can be normatively defined, I'd say. Unless you completely "outlaw" style changes, which of course would never fly with authors and would go against the reality of the web. > On the mobile platform for instance, I sometimes see that one is > unable to use the handwriting feature to input text into a form within > an application ... the developer has unknowningly done something that > has broken the handwriting feature.

But not for the case of presentational styling, at least not in the manner you suggest. P -- Patrick H.
