From IBM comments on June 30, 2005 WD: How is this an accessibility
issue? It needs clarification. If this isn't an accessibility issue
than should remove this technique or provide justification.
Roberto Scano:
This is needed for colour contrast. Without defining a background or a
colour, browser will setup the default theme colour.
Johannes:
Yep, e.g.:
UA stylesheet:
color: #000;
background-color: #ccc
Author stylesheet (assuming a 'default' background-color: #fff):
color: #666
will result in
color: #666;
background-color: #ccc
which may not be enough contrast. The user will need to override the
colour in the author stylesheet by a user stylesheet. But customization
of user stylesheets is not very user-friendly in today's browsers.
