And again, I don't think it's necessarily a valid approach for web applications. Do web designers want a platform specific visual display, or one that's consistent across all platforms? The latter has traditionally been the favored approach with web pages and web applications. > > And since we're talking the web, I'm not sure a progress meter visually needs to reflect the OS. > > I would think that web page designers would prefer a platform agnostic visual effect. > > As with other elements that are typically rendered as UI controls, I think the > default rendering should match the platform, but styling should be able to > override to give a custom appearance. That gives Web developers the choice. > Some Web developers prefer a custom look for all controls, while others prefer > a platform-native appearance. They have that choice with <input type=button> > and we see things done both ways on the Web. > Then it seems to me that we're not really not adding enough new functionality that can't be implemented by existing technologies.
