[wp-hackers] WP 2.5 gallery breaking xhtml 1.0

[Otto]

Do we really want to require themes to remove bits just to make it
work properly for themselves? That's my fundamental issue with all of
this, the core code should not be adding styles and other such
visibility things like that.

The gallery should put a simple unordered list of the pictures into
the post, with useful classes like gallery and such. Then it's up to
the themes to style those.

This is a perfectly acceptable way to do things, and themes and users
*will adapt to it*. We can just tell them to copy the gallery stuff
from the default theme's CSS into their own theme's CSS. There should
not be a need for any particular coding associated with this. All that
has to happen is to remove the styles from the gallery code and move
them into the theme's stylesheets. That's it. Finished.
