And when used as backgrounds for text, the results are unhappy. Sad but
true: many, many users are completely unaware that their "agent" has such
settings, and terms like "dither" and "gradient" are fairly specialized.
Requiring users to reconfigure their defenses for every overblown design is
friendly to neither users nor authors. It seems much more sensible to me to
empower authors to make better choices. I may well wish to specify a
gradient background if I know the display supports enough colors; failing
that, I'd like to specify one or more alternates for the UA to select based
upon my parameters - not the user, based upon his or her level of knowledge
and care.

To end users, there is no difference. Styles can now be parameterized with
@media, but the media types are far too coarse IMO, with at least as much
variation within media types as across them. I'd like to see media
specified in more descriptive, quantitative terms: physical, color, and
audio resolution, typographical rendering policies, connection throughput,
processing speed and available memory, and of course extensive user profile
information, captured in a user style sheet.

But first, a CSS1 implementation would be nice. <g>
